Sensitive Winemaking Equipment Controls Protected By NEMA 4X
Non-Metallic Enclosure
The goal at Carlsen and Associates is to provide the ultimate
in functional, quality winemaking equipment to the wine industry. One of our more popular products is the Waukesha 130
wine and must pump. It is a pump that will do virtually all phases of wine production.
“Our customers purchase our
products because they know they will
perform properly especially during
the peak grape harvesting season,
said David Halstead, general manager,
Carlsen and Associates. “However,
they might not understand the design
work that needs to be done for us to
offer them a quality product. For
instance, our selection of a protective
enclosure for electrical controls was
extremely methodical. During our
research to find the best enclosure
for the Waukesha 130 Electrical
Controls we discovered that we really
needed a NEMA 4X enclosure to
ensure reliable protection from
impact, rain, snow, sleet, windblown
particles and corrosive agents.
Enclosure cabinets typically used
in industrial applications fall under standard NEMA, UL or
CSA guidelines. NEMA 250 is a standard that can provide
assistance for the designers in understanding what the performance requirements are for various physical or environmental conditions.
The internal electrical controls that Carlsen needed protected inside a NEMA 4X enclosure, included variable frequency
drives and control switches. Externally the enclosure had to
work with a removable remote control connector, power cord
and a speed control cord.
“Once we identified the manufacturers that offered NEMA
4X enclosures we narrowed the list down to those who offered
composite non-metallic ones,” said Halstead. “We wanted to
use composite enclosures because we
knew they could handle the constant
wash downs by our customers, were
lightweight to help reduce the weight
of our machines and are a lower cost
option compared to stainless steel.
Carlsen’s next challenge was
selecting an enclosure that had aesthetic appeal. They choose Stahlin's
Classic and J series enclosures to
meet their needs. One of the key
deciding factors was that all Stahlin
fiberglass enclosures are molded
with SolarGuard, a specialized nonhaloginated SMC formula that
guards against damage from constant UV exposure.
Additionally, Stahlin met another
practical need, the ability to modify
enclosures to Carlsen’s exact specifications. Through their ModRight factory-based modification program, Stahlin drilled holes in the
enclosures to the company’s exact specifications thereby saving
time, money and headaches.
Stahlin also recently purchased a Belotti 5 Axis CNC
router that increased accuracy, improved quality from less
handling of parts during the routing process, and gave them
significant machining and routing capabilities from increased
power and versatility. Turnaround time for these custom
enclosures was thus reduced.

Zonex Enclosures Meet Safety Requirements per European ATEX
Directive 94/9/EC
Hoffman has released its ATEX-certified Zonex enclosures, designed for use in potentially hazardous locations where allowable protection methods include increased safety
per ATEX Directive 94/9/EC. Zonex enclosures are suitable for use in Zone 1 and Zone 2,
EEx e, increased safety applications and provide the installed components with
IP66/NEMA 4X environmental protection.
“‘Increased safety deals with controlling (limiting)
the arc or spark of components installed so as to
eliminate the possibility of igniting a gas or dust in
the environment, as well as controlling the surface
temperature of the enclosure,” said Greg Quick,
Hoffman product manager. “Zonex enclosures that
are factory populated with terminal blocks and ATEX
Certified have limits on the number of terminal
blocks installed. By limiting the number of terminal
blocks installed, the amount of heat generated by
the wire and installed components is controlled.
Controlling the temperature rise maintains the enclosure surface temperature below
defined limits, which eliminates spontaneous combustion due to the known flash points
of certain gases and dusts.”
Zonex enclosures are fabricated from Type 316 stainless steel, which provides corrosion resistance in most environments, and the silicone gasket offers added sealing
and temperature performance. Side mounted slotted mounting brackets allow oneperson mounting and installation. Standard enclosures with either one or three gland
plates allow for easy modification and wiring, and a lift-off door allows full access to
components inside.

Nextreme Awarded Seminal Patent in Nanotechnology to Boost Efficiency of Thermoelectrics
Nextreme Thermal Solutions has been awarded US Patent 7,342,169 for "PhononBlocking, Electron-Transmitting Low-Dimensional Structures"
technology that has the potential to impact energy conservation and thermal management. Nextreme's newest patent represents the culmination of work carried out by RTI
International more than seven years ago in the area of nanostructured thermoelectric materials. Nextreme acquired all of
RTI's intellectual property in thermoelectric materials and
devices in 2004.
Thermoelectrics are used to convert waste heat into electrical power, and also for cooling electronics. Numerous
researchers in North America have reported significantly
enhanced efficiencies in thermoelectrics using nano-structured
materials. This includes work on superlattices at RTI
International and MIT that started in the 1990s and more
recently at MIT and Boston College using nano-particles.
The nano-approach uses a commonly available thermoelectric material called
Bismuth Telluride, constructed on a nanoscale to create an assembly that researchers
Orion Fans Develops Dual Voltage Cooling Fans for
Worldwide Applications
Providing electronic and industrial equipment designers
with a cooling fan capable of worldwide use, Orion Fans has
developed a comprehensive line of dual voltage AC fans
designed for electronic equipment and industrial enclosures.
Designated the OA109AP-11/22 series, the 120 by 38 mm
fans can be configured to operate on either 115 V or 230 V.
"As more customers are building products for worldwide
markets, they have been looking for dual-voltage components," said Kevin Knight, marketing manager, Orion Fans.
"We are one of the only suppliers in the industry to develop a standard series of dual
voltage fans for this market and the 120 by 38 mm frame size makes them well suited
believe blocks the transmission of phonons, which carry heat, and enhances the transmission of electrons, which carry electrical energy.
The result is a radical boost in material efficiency with
reports of 40 to 140 percent improvement.
"This patent award is the culmination of years of research
from a pioneer in the field of thermoelectrics," said Dr. Seri
Lee, CTO, Nextreme. "Nano-structured materials hold great
promise for significantly enhanced cooling and energy conversion performance."
Nextreme is already using thin-film thermoelectrics in the
electronics industry by integrating thermoelectric materials
into commonly used electrical interconnects called copper pillar bumps to create a thermal bump. This approach has provided a scalable and inexpensive pathway for integrating thermal management functionality directly into electronic packaging and has enabled Nextreme's OptoCooler module, the world's smallest thermoelectric cooler and the industry's first device to offer a heat pumping density in excess of
70 W/cm2.
for use in fan trays in industrial control cabinets, electronics enclosures and telecommunications equipment applications.
Three standard models of the OA109AP-11/22 series fans are available. These come in
3,000 rpm by 110 cfm airflow at 15 watts, 2,300 rpm by 71 cfm airflow at 11 watts and
1,600 rpm by 51 cfm airflow at 8 watts. All are constructed from die cast aluminum and
all have UL94V-0 glass fiber reinforced thermoplastic impellers.
Typical OEM pricing for 100 pieces of the OA109AP-11/22 series is less than $16 each
with stock available immediately from Orion or Orion authorized stocking distributors.
Smaller, Lighter and Higher Performing IGBT Power
Semiconductor Cooling from Vette Corp.
Vette Corp (Vette) has released its Aluma-Cop liquid cooling device for insulated gate
bipolar transistors (IGBT). Vette's liquid cooling flat tube design enables a smaller and
lighter solution to cooling IGBT power semiconductors across demanding applications.
IGBTs are high efficiency and fast switching
power semiconductor devices and cooling them
to insure their reliability is critical for electric
vehicles and hybrid cars, where IGBTs control
the AC motors and generators connected to the
car's batteries. IGBT power semiconductor applications also include power supplies and uninterruptible power supplies, air-conditioners and
digital amplifiers.
"What makes Aluma-Cop liquid cooling
unique is how we designed the tube,” said Chris Cutaia, president of Vette Corp North
American Power Division. “The flat tube forms a larger, wider cold surface area against
the devices or modules that require cooling. It has a cross-sectional aspect ratio of
greater than four to one with internal integral forged fins creating a flow channel optimized for both fin pitch and fin height to width ratios. This achieves much greater cooling performance than typical designs that simply press a smooth bore round copper
tube into an aluminum carrier block."
Aluma-Cop cooling solutions can provide cooling to an IGBT power semiconductor
device without an aluminum carrier block. In addition to weight and size reductions, this
enables the end user to position the IGBT semiconductor modules by simply loosening
clamps and sliding the modules into their desired position at any time during the product assembly sequence. Vette designed Aluma-Cop tubes to connect together via manifolds to support all sizes of IGBT power semiconductor applications.
New Air Conditioners Designed for NEMA 4 and 4X Enclosures

BTU/H, these NEMA 4/4X Rated air conditioners are well suited for both indoor
and outdoor applications where weather
and corrosion resistance is required
Epoxy-coated condenser coils and
painted galvanized sheet metal in the
Profile Guardian models allow them to
be used in corrosive and other hostile
environments. The NEMA 4X interface
makes these models suitable for applications such as processing plants, where
Government Clean-in-Place (CIP) procedures require routine high pressure wash
downs, and electronic systems need to
be housed in NEMA 4/4X rated enclosures.

Tripp Lite’s New Switched and Metered PDUs Feature
Centralized Configuration and Monitoring Software
Tripp Lite has expanded its line of power distribution units (PDUs) to provide new
options in power capacity, form factor and management. Most new models feature Tripp
Lite's built-in network interface that allows users to remotely monitor and control indi-
vidual outlets and connected
devices via SNMP, Web or Telnet.
"The new PDUs demonstrate
our commitment to provide customers with the highest level of
network functionality," said Rich
Feldhaus, Tripp Lite product specialist. "The switched PDUs allows
network managers to remotely control individual outlets and connected devices by
remotely rebooting locked devices. Users can also extend runtime of critical devices by
remotely turning off non-essential devices during a power interruption. These features
will no doubt greatly reduce the number of costly service calls."
The Tripp Lite PDUs come in some 13 different configurations, four of which are 120
V models that come in varying levels of amps, mounting styles and outlets. The remaining units come in either 208 V or 208 V to 230 V with the same level of customization in
regards to mounting, outlets and amps.
For greater functionality, Tripp Lite offers free PowerAlert network management software to centrally monitor and control power for up to 250 UPS systems or PDUs on
their network. PowerAlert allows managers to mass-configure multiple remote device
settings from a single location and can also be set to auto-discover UPS and PDU
devices in specific network segments or IP address ranges. This software-only solution
saves network managers the installation costs normally associated with other solutions
that require additional hardware or license purchases.
PowerAlert software extends PDU capability beyond central monitoring and power
control. Using Tripp Lite's Environmental Sensor and a SNMP Web card, managers can
also monitor external temperature/humidity and contact closure inputs.
New Surge Protective Devices from 40,000 to 200,000 Amps
Phoenix Contact's Valvetrab-SQ surge protective devices (SPD) offer safe, reliable
surge protection from 40,000 to 200,000 amps. The
NEMA-style product series includes approximately 50
part numbers in three different mountable designs designated by control cabinet (CC), sub-panel (SP) and service
entrance (SE) identifiers.
The VAL-SQ CC series offers an economical method of
protecting electronic equipment in light commercial,
light industrial and residential environments. It has
40,000 amps of surge current rating, and its compact
design is well suited for installation in a control cabinet
or directly to critical equipment.
A multi-phase SPD and noise filter, the VAL-SQ SP
series protects sensitive equipment even in the worst
environmental conditions. It can be installed adjacent to sub-panels or directly to sensitive equipment. It provides 80,000 or 120,000 amps of surge current rating per phase.
The VAL-SQ SE series provides maximum surge protection for the service entrance
and remote locations in industrial, medical and commercial applications. Available with
120,000, 160,000 and 200,000 amp surge current ratings, it can be mounted near the circuit breaker, reducing connecting leads and improving performance.
In addition to surge protection, the Valvetrab-SQ line includes status LEDs, audible
alarms, sine wave tracking filtration and function monitoring. All of the SPDs comply
with UL 1449 2nd Edition, 2007 requirements.
A4BQ Fuses Offer UL-Listed Product Choices for Lower
Ampere-Rated Applications
Ferraz Shawmut has introduced its newly UL-listed Amp-Trap 2000 A4BQ 100 to 600
Amp Fuses, for applications needing Class L fuse dimensions with ampere ratings of less
than 601. Plant and specifying engineers and consultants can use the flexible A4BQ to
comply with OSHA regulations and NEC standards.
Suitable for branch circuit protection, and with Class J
fuse performance, the A4BQ 100-600 fuses meet three specific applications, ensuring flexibility on new construction
projects and future expansions, providing an acceptable
and safe solution for facilities that reduce power consumption by downsizing or consolidating, and meeting arc flash
mitigation needs.
The A4BQ fuses were designed dimensionally for oneway interchangeability, meaning a Class L fuse of any lower
ampere rating can be substituted for a given Class L fuse.
The A4BQ fuses reduce the risk of change orders and save
time and money by using a single fuse class, switch or
holder for all development plans. This minimizes excess
inventory and part numbers.
"In some cases non-listed fuses are being installed into service entrance equipment
and switchgear because there aren't any alternatives," said Bob Lyons, product manager,
Low Voltage Fuses.
"UL standard 248-10, Class L Fuses, doesn't include fuses with ratings of less than 601
amps, and Ferraz Shawmut's A4BQ 100 to 600 Amp Fuses solves this problem."
Similarly, downsizing and consolidation often results in reduced power consumption,
forcing facilities to install unlisted products into existing switchgear or replace existing
service equipment. Ferraz Shawmut enables facilities to replace existing 601 to 6,000 A
Class L fuses with A4BQ 100 to 600 fuses and retain a UL listing.
The A4BQ fuses also provide optimal overcurrent protection to service entrance
equipment, large motors, feeders and other circuits. They reduce the magnitude and
duration of faults for better arc flash mitigation.

access and exclusive access assignments including
master key management, across a range of units.
This ability to mix-and-match key codes among
multiple latch styles answers specific needs across
a variety of industry applications. Industrial enclosures and self-service equipment benefit where
access to specific compartments needs to be limited to authorized individuals.
ther improve the crosstalk behavior ERNI
Electronics has optimized the signal routing
and the pressfit termination of the female
connector. To benefit from the maximum performance of the new ERmet ZD plus the
usage of backdrilling is recommended.
Decreasing via stub length and the related
"stub effect" by backdrilling significantly
reduces the reflections and the overall BER
(Bit Error Rate) of the interconnect.
The first product of the ERmet ZD plus
family is the four-pair right angle female connector with pressfit termination. The ERmet
ZD plus female connector is mating compatible to the existing ERmet ZD male connector. This means, that existing backplane designs do not need layout changes on the
backplane side, if customers want to upgrade their systems. Of course the layout on the
daughter cards has to be modified if using the new ERmet ZDplus female parts.
ERmet ZD connectors were specially developed for differential high-speed signal transmission in telecom applications with data rates of up to 10 Gbit/s. This modular connector system is also very well suited for use in combination with the 2 mm HM (IEC 610764-101) ERmet line of connectors. The special design of the signal and ground contacts
ensures simple and economic conductor track routing. The ERmet ZD connector utilizes
an optimal grid construction that reduces signal interference and offers more room for
conductor track routing. Its optimized design and effective shielding allow the ERmet ZD
system to exhibit superb performance when faced with crosstalk and reflections. Signal
and ground contacts have different connection levels, ensuring reliable mating.

Silicon Diode Array Improves Communication Line Protection
From ESD and Other Overvoltage Threats
Littelfuse, Inc. has expanded its SP72x series of SCR Diode Arrays for electrostatic discharge (ESD) and other overvoltage protection of telecomm and datacom interface circuits. The SP725 is particularly well suited for protection of microprocessor/logic inputs,
data bus lines, analog device inputs and many
other voltage clamp applications.
The thyristor-based design of the SP725 silicon diode array utilizes two bipolar
SCR/diode structures to protect each of the
four inputs (typically external signal or bus
lines). Its operation is similar to what is
known as a steering diode, but it has lower
capacitance and leakage current for a given
impulse rating. This means less chance of
communication signal distortion.
Each SCR structure is triggered on by any current that biases the SCR into conduction against the supply rails. These internally triggered SCRs offer improved impulse
protection compared to conventional diode offerings and will serve a broader range
of applications.
Transients are diverted around the SP725 silicon diode array input lines to the power
supply rails, or ground. Once the discharge current falls below the forward bias levels,
the device stops conducting and returns the input lines to their previous condition. This
design can protect up to 30 V and will protect at around one volt beyond the supply
rail voltage (V+ or V-). The closest competing device protects only at its breakdown
voltage of 18 V.
The SP725 series silicon diode array circuit protection device is available in an 8-lead,
narrow body SOIC package, which can be supplied in tape and reel assemblies. It is
RoHS compliant and fully lead-free, in contrast to competitive units that still use lead
solder for attachment of the IC to heat dissipaters. The SP725 also meets the test
requirements of IEC 61000-4-2 for 8 kV direct discharge and 15 kV air discharge. It also
meets the requirements of MIL-STD-3015.7 for 25 kV testing.
ESI Group’s New PAM-CEM Solutions Handles Realistic
Industrial Models and Accesses Real Electromagnetic MultiScale Phenomena
ESI Group has released the
new version of its PAM-CEM
Solutions software package. This
product is aimed at performing
realistic and predictive electromagnetic compatibility (EMC)
simulations in various industries
including aerospace and defense, electronics, transportation and telecommunications.
When dealing with industrial models, conventional strategies usually rely on either
global, with standalone full-wave Maxwell modeling or local approaches with specialized
tools focusing on induced effects on wiring. PAM-CEM Solutions is able to mix both with
3-D time domain simulations well suited to reflected or diffracted phenomena and
CRIPTE and a dedicated Transmission Lines tool for cable networks. The new version also
pays special attention to the management of large-scale models including several-dozen
million elements (STL or NASTRAN files) and hundreds of wires (close to the real
model), for 3-D computations featuring billions of unknowns.
Key enhancements to PAM-CEM Solutions include improved management of large STL
models and NASTRAN files featuring several-dozen million elements, with a faster
importing stage, easier management. Full interactive addressing of cable networks,
including dynamic allocation, management of different loads on terminal connectors,
full specification of voltage and current generators and generation of all data files with
the display of cross sections and tubes content,
has also been included.
In order to allow an efficient management of
large-scale fully equipped models, the 3-D computational stage was also upgraded and CPU optimized, together with more post-processing capabilities, such as surface currents display, extended
multi-frequency output of all relevant results starting from one single 3-D run, modeling of lossy
dielectric grounds through dedicated PML (perfectly matched layers) boundary conditions, etc.
PAM-CEM Solutions is available on Windows XP
or UNIX platforms (HP, SUN and IBM) and for
LINUX kernels (32- and 64-bit versions).

Leveler’s iPURE Power Conditioner Protects High Performance
A/V Electronics
Leveler Protective Technology has introduced the iPURE AV2400 power conditioner,
which is designed for proper protection of audio/video electronics. The patented technology of the AV2400 controls voltage while it dissipates excess amperage and diverts no energy to ground,
the backdoor or the guts of electronics. The iPURE features noise and
surge filtration that treats all AC
power lines simultaneously – line,
neutral and ground.
Designed to deliver pure, constant
power to sensitive electronics, the iPURE eliminates 99 percent of AC line noise. This
translates to better pictures on a plasma, mirror projection or LCD HDTV and the lowest
possible sound floor in a commercial movie theater or home theater.
Importantly, the iPURE can improve by 30 percent the power efficiency of electronics
systems. The result is increased electrical capacity and more power readily available for
big A/V component demands. This power conditioner also cuts energy waste by converting harmonics that cause damaging heat build-up into usable energy.
Cool-running iPURE uses no energy to perform its functions, requires no maintenance and meets or exceeds all safety standards. Leveler is an Energy Star Partner and
designs and manufactures the iPURE in the USA.
Shipping now, the iPURE AV2400 has a sleekly designed, black steel and aluminum
enclosure and is available in rack-mount or stand-alone models. At 20 amps, it has 10
outlets in two isolated 10-amp banks that separate audio and video power sources so
harmonic crossover is not possible.
turn off subsystems to draw less current," said Gary Whitman, vice president and general
manager of Agilent's System Products Division. "Engineers in R&D and manufacturing are
challenged to find a power supply that can accurately and quickly measure their DUTs'
sleep mode and leakage current, without inducing troublesome voltage glitches. Agilent's
patented technology can measure microamp currents to enable better designs and faster
test times of cell phones, Internet appliances, radios and other portable electronics."
Agilent's N6700 family of power supplies with microampere current measurement
technology have fast transient response at high currents and are capable of fast, accurate,
low-level current measurements. These power supplies can make small current measurements faster because they do not need to wait for large internal capacitors to charge and
signals to settle. The patented design does not induce voltage disturbances (glitches),
making it easier to apply and safe for the DUT. This technology, available as option 1UA
to the Agilent N6760 Precision DC Power Modules, allows microampere current measurements to be made in a few milliseconds with only 100 nA of offset error, while still meeting transient response time of less than 50 microseconds for currents of 2 amperes.
Because these Agilent power supplies can measure low currents quickly, manufacturing
test system engineers do not have to wait for current measurements, increasing system
throughput, which is critical to maximize the use of expensive ATE equipment. These
same power supplies can be used in R&D applications where the measurements need to
accurately characterize total device power consumption and impact design decisions.
Agilent N6760 Precision DC Power Modules are supported in the Agilent N6705A DC
Power Analyzer for R&D and in the Agilent N6700 Low-Profile Modular Power System
for ATE. These products are all part of the Agilent Modular Power System family.
New Digital Infrared Temperature Sensor for OEM Usage
HL-Planartechnik has introduced a new member of the
IR sensor family, the TSEV01P. The benefit of this OEM
module is a strong integration leading to a radical reduction of the outer dimensions of the sensor combined
with a strong reduction of the power consumption.
HL Planartechnik has long been developing and manufacturing MEMS infrared temperature sensors. These so
called thermopiles are used to measure temperature in a
very fast, precise and contactless way. The sensor, housed
in a TO metal can, provides an electronic voltage
depending on the incoming infrared radiation. Additional
electronics are applied for analogue and digital signal
processing in order to compute the surface temperature
of the object of interest. With HL Planartechnik’s product family TSEV, all of these functionalities have been integrated to an electronic assembly on one PCB.
Thus TSEV01P is well suited for consumer and handheld applications including mobile
phones, PDAs, battery operated (non-medical) thermometers, toys and many industrial
devices which have limited room. The calibrated and temperature compensated sensor
system TSEV01P is equipped with a digital interface in order to provide straightforward
integration to any systems.

What's on Your Old Hard Drive? A Look at Digital Security in
Hard Drive Disposal
Justin C. Lauzet, Marketing Associate
WiebeTech – A Brand of CRU-Dataport
There is, despite a number of tools available, a socially lax attitude regarding hard
drive disposal. This article discusses common myths about "deleted" data, the disadvantages of software disk erasing tools, and the lax security regarding hard drive disposal.
I. The Immediate Problems and Myths About
File Deletion
The first problem is clearly a lack of knowledge
about how operating systems handle hard drives. The
second problem is that users of computers (thus hard
drives) are failing to recognize that they have personally
identifiable information worth securing. Knowing what
is on your hard drive and how to erase it can help prevent identity theft, credit card fraud or even personal
photographs and embarrassing online conversations (as
examples) from being discovered and exploited.
As a digital culture we worry more about network
security than we do about security in hard drive disposal. Firewalls and network passwords mean little if the
data being protected is not erased properly when the
hard drive is no longer used.
Myth 3) There's Nothing Interesting on My Drive (There Probably is)

II. Software Solutions vs Hardware Solutions
There are plenty of software drive wiping utilities that are available, some of them free and
most are capable of multiple passes. In many
cases, they work just fine. However, software solutions do have inherent problems, listed here:

Many users disposing of a single Hard Drive on their own could be well suited with
the right software utility. They're clearly better than not using anything. However, we
believe slow speeds and a required dedicated computer to be the cause for so many
drives failing to be erased properly.
III. DoD Specs, Gutmann's Research, and What is "Good Enough" for Most Users
The specifications from the Department of Defense (DoD) and Peter Gutmann's 1996
research are considered benchmarks in the disk erasing industry for qualifying hardware and software.
Unlike most users, the Department of Defense considers the sensitivity of the drive's
contents. One pass of data to all bits across the disk is good enough to "clear" a drive,
according to the DoD. Remember that the Department of Defense deals with classified
and top secret information. Before June, the DoD would allow "sanitization" with hardware and software, with various algorithms depending upon where you looked. As of
June 28, 2007, however, "sanitization" of classified data requires degaussing machines, which will almost surely damage the drive beyond repair,
or more obvious methods of destruction of the disk [1].
Gutmann's research, titled "Secure Deletion of Data from Magnetic
and Solid-State Memory", has since caused a stir in the industry. Many
software applications make mention of Gutmann's research, and claim
that an incredible 35 passes are necessary for secure erasures. What is
not traditionally reviewed, however, is what would actually be necessary
to read data back with more than one pass, according to Gutmann. From
Gutmann's paper, "Magnetic force microscopy (MFM) is a recent technique for imaging magnetization patterns with high resolution and minimal sample preparation. The technique is derived from scanning probe
microscopy (SPM)" [2].
In the 11 years that has passed since the paper's debut, we've witnessed ever increasingly small (physically small) block sizes. And with bits
that small, data being spread out between four read/write heads, and
wide number of available disk formats, the specific knowledge and cost
involved in such a technique are overwhelming, and the actual success of
which comes into question.
The laboratory required for such a technique is very expensive, and
the knowhow is rare. While the common computer user should worry
about how they dispose of hard drives, they should limit their worry. The
conclusion, here, is that for most people 35 passes is unnecessary. For
the few people who it is necessary for, it's simply easier to destroy the
drive - those people obviously have more important things to do. "Good
enough," for most people, is one (or several, for the more concerned)

IV. Conclusion - What is Necessary Before Releasing Ownership of a
Hard Drive
Most people should consider the following recommendation adequate.
It can be done quickly, and with relatively little expense. It's not too little
and it's not too much:
At least one erasure pass across the drive, with
data being written to every bit, properly handling
HPAs/DCOs and a quick check that it worked.
If we cannot trust the hard drive to read back
what was last written to it, then we would not be
able to trust it as a storage device. A drive's single
job requirement is to read back data that was
written to it before. Thus, writing data to every bit
of the drive ensures that future reads will not
somehow read back old copies of the data. The
technique to read old data (data already written
over) requires a magnetic force microscope.
Answer this question: Do you know anyone
with a magnetic force microscope - or do you
think the data stored on your drive is worth
someone obtaining one? If yes, destroy the drive.
There are plenty of techniques for this. Otherwise,
you can rest comfortably that software programs
are not going to be able to reconstruct your data
if you've followed the recommendation.
As discussed, when it comes to hard drives,
many users have a false sense of security while
doing nothing or trusting basic techniques which
do not do anything to our data. Further, those
who know how to erase drives properly with software might not do so correctly because of the
amount of time required for each drive. While we
do not have to go overboard with 35 passes, we
do need to worry.

Proactive Vandalism Abatement and Prevention Saves
Dollars and Makes Sense
Dirak gmb&H & Co. KG
Modern vandalism presents a tangible problem for law
enforcement agencies and companies. Public buildings,
outside facilities and facades frequently are victims of
unmotivated destruction. For example, annual vandalism against railroad systems in any given country can
equate to double digit figures (in the millions), and the
trend is intensifying.
This increasing phenomenon stems from rising copper
prices which are causing a spike in copper theft. The US
is the world’s second largest consumer of copper.
Therefore, it is not surprising that the more expensive
copper becomes, the more copper theft rises. Freestanding junction boxes or telecom network boxes are
inviting targets for criminals. Even though no large
amounts of copper are being used, the destruction and
service interruption are significant, with considerable
financial implications.
Copper-Theft and Vandalism
Nearly everyone is aware that vandalism and coppertheft are the result of social problems and global economical structural changes. For vandals, network boxes,
transformer stations and other publicly located distribution equipment are easy prey. Enclosures are easily
accessible and are rarely secured, so offenders usually
go unnoticed. Manufacturers and operators can no
longer be complacent and rely solely on police protection. They must proactively be involved in vandalism
abatement and prevention.
Security Priority
“The rise of vandalism is a sad phenomenon of our
times”, said Georg Huebner, product manager for Dirak.
“We can’t fight against the social background and circumstances which are the root problem. Those that rely
on us for their industrial hardware also rely on us to
provide products with the highest security and vandalism resistance”.
Currently, there are no international standards to address
this issue. Subsequently specifications are geared
towards those used in residential construction for windows and doors. Burglary prevention continues to be of
the highest priority.
The basic idea is as simple as it is logical, handles and
latching systems that offer serious resistance against burglars provide an insurmountable obstacle for the less professionally equipped vandals and copper-thieves. Using
this as a design benchmark for the swinghandle equates
to a resistance rating of two. This norm represents the
time that residential locks have to resist criminal energy.
The logic implies that the longer a burglar is unavailingly
tampering with a door, the sooner he/she will give up.
Vandals that attempt to crack through secure systems will
often give up. The deterrence factor stems from superior
systems that provide protection. With such systems,
equipment damage is minimized.
“We need to put ourselves in the shoes of these modern
day vandals,” said Huebner. “While their motives and
actions are very obscure, destructiveness usually follows
the path of least resistance. Power equipment or a traffic
light system typically show insufficient protection and
become likely targets versus an enclosure that provides
massive resistance against petty thieves.
Levers, Hinges and Multi-Point-Latching Systems
A security concept is based on
several elements. For starts, use
a time-tested key locking system. In outdoor applications,
these have widely replaced simple latches that basically just
prevent a door from staying
open. Dirak often increases the
lock’s protective function by
using it in conjunction with a
swinghandle. By restricting
access to the actual latch, the
burglar’s starting-point is
removed. Flush-mounted
latches also make gaining
access difficult for vandals,
because these latches don’t
offer a starting-point for a
screwdriver, which is quite
often the only tool they carry.
Multipoint latches with rodlatches can also be effective against forcible door access
attempts. They latch the door securely in several places
for protection against unauthorized access. There are
also a variety of hinges available as well. For sensitive
outdoor applications, concealed hinges are ideal, because
they don’t provide a starting-point to force open a door.
Subsequently, vandals usually give up.
Product materials also play
an important role in good
security and should not be
underestimated when trying to prevent vandalism.
Stainless steel handles and
latches provide massive
resistance against most
simple tools.
The initial costs of these
systems are part of our
company’s security commitment. The additional
costs for increased security
are nominal when considering the overall application cost. Therefore, it is
recommended to equip all
outdoor systems with

enormous direct and indirect damage associated with vandalism, an investment of
this kind is worthwhile – particularly for power distribution equipment, data and network cabinets.
Controlling Indoor Vandalism and Protecting Data
Theft is Another Challenge
In today’s world of information technology, it is crucial
for financial institutions, medical facilities and government agencies to safeguard personal data. Personal data
theft and identity theft is a huge liability, thereby requirement huge financial investments to safeguard critical data
and personal information.
Chances are that such data is stored on servers that are
housed in enclosures in data centers. Since there is a
substantial amount of foot traffic in and out of data
centers each day, it is equally important to
secure individual enclosures in addition to the
perimeter doors of the data center.
Electromechanical Swinghandles Provide
Added Security for Individual Enclosures.
Items that can help combat indoor vandalism and
reduce data theft include electromechanical
swinghandles that protect each individual enclosure. Only authorized individuals will be granted
access to a specific enclosure(s) at any given

moment. Because each transaction is captured, there is
an electronic paper trail of who entered a specific cabinet
and at what time.
Each swinghandle serves as a user-friendly and reliable
method for monitoring access to server cabinets via the
swinghandle and master control software. With each system, the user is able to monitor the entire access system
of server cabinets from a single workstation. Cabinets can
be locked from this central point to prevent unauthorized
access. Since everything is captured electronically, there is
a documentation trail of each attempt. Systems such as
this can also alert users if a cabinet has inadvertently
been left open for an extended period of time.
Let’s say that everyday at a specific time, a backup of the
data is done. These systems will allow the user to temporarily lock out all users between certain times, so that
the data backup can be done without interruption. If
there is a loss of power, access can still be granted. In some cases, the system can be set-up to
require two individuals be present before the system grants access to a specific cabinet.
Conclusion
As vandals become more sophisticated in their approach
to data theft, it is crucial for companies to be aware of
the many options available on the market to help prevent
the ever increasing liability of data theft. An upfront
financial investment is minimal in comparison to what is
at stake and what it would cost to have to undo the damage done by vandals. Electromechanical swinghandles
provide added security and peace of mind to those individuals who are responsible for the daily safeguarding of
data centers and the information that they contain.
It is a given that vandals will continue to find new ways to
destroy equipment and steal things such as copper wire
and confidential data. However, there is comfort in
knowing that there are a number of standard systems as
well as customized solutions available on the marketplace
that can help deter vandals and reduce theft.

These systems are designed to be compatible with
each other to ensure the optimum network structure, despite different local conditions. Since
everything is electronic, there are no keys
involved, which eliminates the need to make new
keys should one be lost.
An active-direct system is well suited for the integration of cabinets, which can be located in multiple geographical locations, rooms or buildings.
The system uses an active key for the authorization of access at the swinghangle. This key enables
the user access to other safety systems as well.
By configuring the automatic login and logout at
the sever and PC, authorized users are granted
access as soon as they enter the work area. When
the users leave the work area, the users are automatically logged off. The installation expenditure
is minimized, because of the linking of the system
via TCP/IP.
Software tracks cabinet entry and exit, as well as
automatic login at the server or PC to authorize
access to the work area. The entire system can be
linked via a TCP/IP connection.
Other basic options can help when integrated into
an existing security access control system with a
hardware interface. This can be used in combination with e.g. RFID-systems, biometrical systems,
rack monitoring, combination locks and other systems. These systems can be linked to the existing
security system via dry contacts that are located
on the control box.
Wireless-Active integration is also feasible by
installing additional hardware that allows the system to be linked to the TCP/IP network. The
wireless gateway acts as an interface for the wireless communication between the swinghandles
and the wired network. This system is ideal to use
if minimum wiring is desired. An active key is
required to gain authorization to any enclosure.
Other options would include HID which is recommended when there is a large amount of enclosures to link and secure.

FEATURE
Switches & Circuit Breakers: To Hermetically Seal or Not
Ken Schwinn, Director of Engineering
APM Hexseal
Not every unsealed or sealed panel switch, potentiometer, or circuit breaker needs environmental exposure protection from adverse conditions on the ground,
in the air or on or under the water. But, for those controls that must operate where dust, dirt, moisture, water,
lubricants, fungus, snow, ice and extreme temperatures
prevail, there is a definite need to protect (armor) them
from contaminant invasions that interfere with their ability to perform reliably. There may also be RFI/EMI spurious
signals seepage that must be prevented from migrating
through the control mechanism enclosure and mounting
hole cut out.
It isn’t just contact-corrosion or fungus build-up that is
problematic. Actuator freedom must be maintained during all operating conditions. Water or snow turning to ice,
and/or dust, dirt and other material build-up in a toggle’s
bushing cavity are just two conditions that can prevent
smooth toggle, pushbutton or rocker operation.
Individually or together, these negative factors can greatly
affect the life, performance and reliability of these unprotected controls.
Do Sealed Switches Need Sealing Boots? Yes & No.
Why do many specifiers of hermetically sealed switches
and circuit breakers also specify silicone rubber sealing
boots? At first glance, this may seem counter intuitive,
but there are several very compelling reasons for this.
In the real world, even “sealed” switches frequently
require additional external sealing. For example, these
sealed switches can suffer from exposure to high-pressure
wash-downs, or extreme hostile weather conditions. Ice
or other material build up in the actuator cavity can easily
happen, preventing toggle movement and interfering with
operational reliability.
The one sure way to completely protect them is to
mount an elastomeric non-gassing silicone rubber hermetic sealing boot with molded-in mounting-nut over
their exposed surface. It is important to note that the silicone rubber is a high performance, non-gassing type that
conforms to A-A-59588 or type ASTM D-1418 . This prevents the possibility of silicone molecules from reaching
and coating sensitive contact surfaces.
The control’s panel mounting hole cut-out is also an
accident waiting to happen. Spilled soda, coffee or any
liquid, lubricant, dust or moisture can easily penetrate the
switch/breaker mounting hole and contaminate sensitive

developed for the US Navy soon after the end of World
War II. They have since become standard military equipment in a wide variety of combat and non-combat applications, from missile launch control systems to night
vision goggles to construction vehicle electrical systems,
effectively preventing invasion of a wide variety of environmental attacks from salt air & spray to high pressure
wash-downs. Industry has benefited from this military
experience. Today millions of these hermetic sealing
boots are in use throughout the world mounted on a
myriad of communications equipment and instrumentation, commercial marine, medical, process industries and
wherever hostile conditions exist.
The anatomy of a hermetic sealing boot
For sealed switches that don’t require the total environmental benefits of a sealing boot, APM developed a
special reusable switch-breaker bushing sealing washer
that solidly locks into the bushing, and can replace any
O-Ring or conventional
washer. This specially
designed stainless steel
washer has a bonded hightear strength silicone sealing ring, strong enough to
effectively stop hostile contaminates and wash-downs
from penetrating the
panel. An inside I.D. finger
Bushing seal for sealed switches
locks into the vertical bushing groove preventing rotation.
The final determination of which sealing technology, if
any, is required is generally based on product experience
with the selected switches/breakers - beyond and including environmental lab testing. When a specified component does not meet the desired NEMA/IP rating, Hexseal
hermetic boots provide the added protection required;
plus the other desirable benefits.
Finally, factored into every decision are the equipment
warranty period and the cost of field servicing, and the
prospect of unwanted recalls. Hexseal sealing boots are a
reasonable cost solution. Hexseal sealing boots were first

Applied Math Modeling Partners with ANSYS to Distribute and
Support CoolSim
Applied Math Modeling, Inc. has entered into an exclusive agreement with ANSYS,
Inc. for the distribution, support and ongoing development of CoolSim, a product
focused on modeling the thermal environment of data centers. CoolSim is a hosted
product that utilizes ANSYS CFD solvers to compute the temperature, pressure and airflow within a data center.
"According to the EPA, companies can achieve up to 30 percent greater energy efficiency simply by improving the airflow within the data center, said Paul Bemis,
CEO,Applied Math Modeling. With data centers consuming an estimated $4.7 billion
according to the EPA's most recent report to Congress, the opportunity for cost savings
and improved efficiency is significant. The market opportunity is significant, and we are
pleased that ANSYS has chosen us as a strategic partner to help IT organizations solve
these important challenges.”
CoolSim uses a graphical interface to enable users to create a model of their data
center. The model is then automatically submitted to a hosted server for processing
where results in the form of HTML output reports and 3D visual images are produced
and sent to the user. This mechanism allows users to perform multiple "what-if" studies
of their data centers to determine the optimal placement of equipment, or the effect of
adding equipment to an existing data center.
"We are very pleased to enter into this relationship with Applied Math Modeling for the
distribution, support and ongoing development of CoolSim," said Chris Reid, vice president
of marketing, ANSYS. "This will enable the ANSYS CoolSim solution to reach a much
broader audience by providing additional focus and domain expertise in the key target
application of data center thermal modeling."
Pelican Products Canada Awarded Contract for Military
Transport Case
The Canadian Military has awarded a contract for 33,000 co-polymer cases from Pelican
Products, Inc. The cases are to be issued to every soldier in the Canadian Forces to transport personal and military equipment.
The enclosure is an advanced design of Pelican’s 1630 Protector Case, and was
designed and tooled with needs of the Canadian Military in mind. Kevin Deighton, V.P. of
New Product Development, led the development team. “We have intimate knowledge of
the superiority of our co-polymer injection molded products. That means we will invest
in a 12,000 pound tool with confidence that we will win the target contract, in this case
the Canadian M.O.B. Case.”
Because of its versatility, the Canadian Forces have designated the case as the MultiOperations Box (M.O.B.). In addition to the light weight polymer wall material, the case
has wide, ball bearing wheels for transport over rough terrain and an extending tow handle with memory that flexes on impact. A key attribute of the case is the use of an o-ring
sealing lid that closes tight with a tongue-and-groove fit. This, in combination with a
Gore-Tex membrane pressure equalization valve, makes the M.O.B. case watertight.
With more than 8,250 cubic inches of usable storage space, the 1630 MOB Case is
well suited for safely transporting and protecting operational and follow-on equipment
including the standard Canadian Forces C7-A2 military issue rifle which stows inside the
case without the need for complete weapon breakdown.
The 1630 MOB Case is designed with unique Canadian Forces requirements including a
specially formulated (Federal Standard) brown case color, hot-stamped Canadian flag decal,
and two removable 4 by 6 inch clear identification document holders. These
are just a few of the features
required by the Canadian Forces
to support military deployments
throughout the world.
Stego, Inc. Current suppliers, including Adalet, Meriam, Hammond and Vynckier have
also increased their product offerings.
A special emphasis was placed creating an easier-to-navigate layout to ensure customers
found their products quicker and easier. Because of this, AD Products customers will
notice the increased functionality and easier navigation starting right at the home page.
Customers can begin their search for products via a number of ways: by product categories, brand, or keywords via a "Quick Search Box." Catalog searches can be done using
multiple filters at the same time, i.e. category, keywords, brand, price, etc. For those
searching specifically for enclosures, the enclosure dimensions can be inputted and all of
the options meeting those criteria will be available, no matter the material type.
With the new site, many features are accessible in just one click. This includes account
updates and management to accessing previously placed orders for reordering. The
enhanced site will send e-mails to customers to let them know their order is received,
processed and shipped. The AD Products site also features quantity discounts, free ground

DATA CENTER SOLUTIONS
CPI Passive Cooling Solutions: A Simple,
Efficient Choice
Chatsworth Products, Inc. (CPI) Passive Cooling
Solutions provide thermal management to reduce data
center operating costs, maximize cooling unit efficiency
and minimize environmental
impact, making them the a efficient choice. Used with CPI’s
TeraFrame family of cabinets,
CPI Passive Cooling Solutions
present techniques to maximize
airflow throughout the data
center without the need for
additional CRAC units, in-row
air conditioners or risky liquid
cooling solutions. From small
applications with heat loads of
2 kW per cabinet, to large
applications with heat densities
beyond 20+ kW, CPI Passive
Cooling Solutions provide
advanced thermal control with
zero points of failure, thus
delivering a Tier IV solution.
CPI passive cooling solutions benefits Include lower
construction costs relative to active cooling solutions with
no additional power or plumbing requirements necessary
and a reducation in operational costs by completely isolating hot exhaust air from cool supply air, maximizing
cooling unit efficiencies.
The cooling solutions reduce energy consumption by
providing 100 percent HVAC utilization of cool supply air.
Thi reduces energy costs up to 40 percent over the standard open air return methods (hot aisle/cold aisle), and
up to 90 percent with certain types of economizers when
utilizing “free cooling” days.
Passive cooling allows for raised set points (thermostat
setting) on cooling units, lowering energy consumption
and costs.The system also blocks by-pass airflow around
equipment, reducing wasted cooling capacity. This helps
allow for higher Delta T’s between the data center\cooling air and exhaust air, which maximizes cooling
unit efficiencies.
CPI’s system permits higher heat densities/power densities based on maximizing cooling efficiency. It also permits chilled water temperatures to be increased providing
means for more economizer days.
Additional features include Tier IV operation with no
moving parts that require redundant systems, as well as
the elimination of dependence on close proximity of
perforated floor tiles to cabinets by creating a consistent
air temperature throughout the room.

New Real-Time Infrastructure Monitoring
Extends the Life of Data Centers and
Forecast Requirements
Aperture has added real-time monitoring technology to
its data center management system, Aperture VISTA. The
new solution, Aperture Vista Infrastructure Monitoring,
provides data center management with an IT view into the
data center while monitoring and managing the status of
the entire physical infrastructure in real time.
The solution addresses a set of fundamental problems
faced by data center management across IT and data center facilities functions. Vista Infrastructure Monitoring provides the IT organization with the information needed to
right-size infrastructure resources to meet business
demands, proactively manage data center capacity and
improve energy efficiency. By providing real-time information on power consumption, data centers can reclaim overprovisioned resources and extend the life of data centers.
The solution also improves energy efficiency though
improved measurement accuracy. Aperture Vista
Infrastructure Monitoring provides real time information
down to the rack level, enabling organizations to determine key energy efficiency metrics such as the Energy
Efficiency Ratio (EER) as defined by the EPA. With worldwide energy costs rising rapidly, data center management is on the lookout for any opportunity to improve
energy efficiency.
Aperture VISTA Infrastructure Monitoring also alleviates
the daunting challenge faced by data center management
that currently relies on multiple management consoles for
alerts and alarms. The solution provides an alternative, with
a vendor-neutral, real-time and single view of the data center infrastructure though a “single pane of glass”.
Correlated with the Vista configuration repository, this provides the impact analysis required to determine the potential effect on the business of an alarm.
Aperture Vista Infrastructure Monitoring is the result
of Aperture’s acquisition of The Advantage Group (TAG)
in July 2007. TAG’s vendor-neutral monitoring technology
has been fully integrated into Aperture’s VISTA solution
to create a comprehensive data center infrastructure
management system that spans strategic activities such as
capacity planning, impact assessments, cost analysis and
management reporting, and day-to-day operational activities such as monitoring and alerting.
“Aperture VISTA Infrastructure Monitoring is a vital
component of our solution, both for us in terms of our
company strategy and vision, and for our customers in
terms of the serious challenges they are facing as data
centers become more expensive and complex to manage,” said Bill Clifford, CEO, Aperture. “Our customers
increasingly need one overarching solution to help them
to manage the data center at lowest cost, while still
meeting business objectives today, and to plan and budget accurately for future data center expansion. That is
what we can now deliver.”
Aperture VISTA Infrastructure Monitoring is the first
commercially available data center management application that allows equipment from different vendors to be
monitored in real time from one single, web-based console, saving time, effort and software integration and
maintenance costs.

Degree Controls Enhances Data Center
Efficiency Offerings
Degree Controls, Inc. (DegreeC) has unveiled the
AdaptivCool Room Scale Intelligent Cooling (RSIC), a
full-service thermal management solution that
reduces data center
energy consumption
and cooling costs.
AdaptivCool RSIC is
the next-generation
version of
AdaptivCool, which
entered the market
in 2006, helps customers reduce data center energy
consumption and increase computing load without
deploying additional cooling capacity.
AdaptivCool RSIC’s temperature sensors send information to a cooling resource manager that calculates
minute-by-minute cooling demand and controls data
center airflow dynamically via floor and ceiling-mounted air movers. Cool air is optimally directed to equipment that requires it and hot air is returned back to
the air-conditioning unit reducing over-cooling, eliminating hotspots and reducing electrical consumption
for data center cooling by up to thirty percent.
An AdaptivCool RSIC installation begins with CFD
modeling, which produces a thermal map of the customer’s data center. From the model, DegreeC develops a tailored RSIC configuration for the data center.
Features for the RSIC include a real time monitoring and control GUI that provides a real-time display
of hardware status, individual sensor readings and
thermal history and trends. These conditions can also
be monitored securely online.
Notification alarms can be sent by the RSIC if one
there’s a CRAC failure or warning, high CRAC return
temperature, high CRAC supply temperature, high
room temperature, high rack intake temperature, RSIC
equipment malfunction and network communication
errors. These alarms can be redirected to AdaptivCool
personnel for evaluation, analysis and prompt action.
“Our research over the last two years shows that
today’s data center and IT managers face a growing
number of challenges, not the least of which is rising
energy costs. They are looking for cost-effective
solutions to ensure that their data center is running
as efficiently as possible, and in many cases looking
to add additional computing loads,” said Coy Stine,
AdaptivCool’s engineering manager. “AdaptivCool
RSIC allows customers to monitor their data center
heat load in real time and make intelligent decisions.”
RackSolutions Launches New LAN and
Power Assembly System
RackSolutions has released two new systems that
work together to create a new standard in network
and power management for computer servers. The
system consists of a Local Area Network (LAN)
Assembly and Power Assembly that keep a high density of cords organized and out of site, providing a
clean LAN and power management system.
When used together, the LAN Assembly and Power
Assembly provide complete power and LAN ports for
ultra-dense server installations, eliminating messy cabling
issues associated with other installation methods.
May/June 2008
With the new LAN Assembly system, the installer has the flexibility
of using the exact number of ports,
the exact type of port, and the
exact location of the port for ideal
cord management. The ports are
color coded and labeled for quick
identification of different Network
segments. The main cable trunk is
routed from the overhead cable
tray directly into the LAN
Assembly. Each cable is punched
into the standard Keystone Jacks
and is hidden inside the product.
A variety of different Keystone
Jacks, that can be purchased separately, makes this a perfect solution
for Voice over IP (VOIP) installations. Additionally, the
product connects the servers to the network with the
shortest possible cable through a cable management arm,
eliminating unnecessary cable disarray.

Easi-Set Industries
Easi-Set® originated the concept of a Transportable Precast
Concrete Building. For years the Easi-Set® and Easi-Span
Buildings have led the industry as the precast buildings of choice.
The patented post-tensioned building system provides even greater
weather-tightness and impact resistance for the precast roof and
floors.
Easi-Set Buildings provide durability, flexibility, convenience, costeffectiveness and long lasting security. Easi-Set Buildings are
installed in a day, require no foundation and are relocatable! EasiSet buildings are used for Storage, as Pump Buildings, for Power
Substations, to house Communications Hardware, by Utility
Companies, for HazMat Storage, as Restrooms (wet and dry), as
Concession Stands, for Classrooms, and many Custom
Applications. Where larger buildings are required, Easi-Span provides clear span sizes up to 40' x 200'.
Easi-Set and Easi-Span Buildings are manufactured nationally by
local producers and are a licensed product of Easi-Set Industries.
Used in conjunction with the LAN Assembly, the Power
Assembly also reduces cord confusion by cutting down
the distance the power cable from the server must travel
to plug into the power receptacle. The power receptacles
are located exactly where they need to be in the rack and
there is no need for extra or non useable receptacles.
This Power Assembly requires a licensed and bonded
electrician to install. This method has the capability of
providing a tremendous amount of power to a server
rack. Most power strips are available with 15 A or 20 A
breakers and between eight to 24 outlets. With the
Power Assembly, it is possible to provide 3.75 A per Rack
Unit, which equates to 187.5A in a 50U Server Rack. To
achieve this amount of power would require 13 to 15 A
power strips.
The LAN Assembly and Power Assembly are currently
available in two sizes, the 44U, which comes with 80 ports
and the 50U, which comes with 100 ports, at a suggested
retail of $349 each. Customers can also purchase these
two systems separately, in both the 40U and 50U sizes.
Additional ports and power kits are also available.
