Introduction
The Cisco uBR Advanced RF Switch (Cisco UBR-RFSW-ADV) provides N+1 line card redundancy switching
for the Cisco uBR10012 universal broadband router also known as the Cisco CMTS. The
Cisco UBR-RFSW-ADV is a rack-mount unit controlled by the Cisco uBR10012 router.
• Overview, page 1
• Cisco UBR-RFSW-ADV—Hardware Components Description, page 5
• Interface Overview, page 16
Overview
The Cisco UBR-RFSW-ADV is located between the Cisco uBR10012 router and the cable plant. All the RF
downstream (output) and RF upstream (input) ports of the Cisco uBR10012 router are connected to one side
of the Cisco UBR-RFSW-ADV, while the cable plant is connected to the other side.
The Cisco uBR10012 router supports up to eight cable interface (RF) line cards. Each line card supports a
single downstream Universal Cable Holder (UCH) connector (five RF ports per connector) and two upstream
UCH connectors (ten RF ports per connector).
When supporting N+1 redundancy, the Cisco uBR10012 router allocates one of the eight line cards as a protect
line card.
There are 24 cards on the rear of the Cisco UBR-RFSW-ADV. Each card supports one UCH connector. These
cards are arranged in eight groups of three cards each. In the middle is the protect card group, which consists
of one downstream protect and two upstream protect cards (see Figure 2: Cisco UBR-RFSW-ADV—Rear
View (CMTS Side), on page 3). This protect card group connects to the Cisco uBR10012 router protect
line card. To either side of the protect cards are groups of switch cards—one downstream switch card and
two upstream switch cards per group. These groups of switch cards connect to the remaining line cards on
the Cisco uBR10012 router.
On the front of the Cisco UBR-RFSW-ADV are 21 interconnect cards. These cards are arranged in seven
groups of three cards each. Each group contains one downstream interconnect card and two upstream
interconnect cards. These interconnect cards connect to the cable plant.
When the Cisco uBR10012 router and Cisco UBR-RFSW-ADV are not in protect mode, each interconnect
card group is switched to a corresponding line card on the Cisco uBR10012 router. However, when the Cisco
Cisco uBR Advanced RF Switch Hardware Installation Guide

Introduction
Overview
uBR10012 and Cisco UBR-RFSW-ADV are in protect mode, the interconnect card group associated with the
failed cable interface line card is switched to the protect line card group instead.
The Cisco uBR10012 router manages all protect switching control plane events and system upgrades.
Cisco IOS Release 12.2(33)SCG and later releases for Cisco uBR10012 router are required for operation with
the Cisco UBR-RFSW-ADV. When the Cisco uBR10012 router determines that a cable interface line card
failure has occurred, it enters into protect mode and additionally commands the Cisco UBR-RFSW-ADV to
enter protect mode.
The Cisco UBR-RFSW-ADV supports the following line cards on the Cisco uBR10012 router:
• Cisco UBR-MC20X20V
• Cisco uBR-MC3GX60V
The Cisco UBR-RFSW-ADV enhances overall system usability by providing easy cabling using the same
quick-connect UCH system used on all Cisco uBR10012 router cable interface line cards.
The Cisco UBR-RFSW-ADV provides the following enhancements over the earlier Cisco uBR 3x10 RF
Switch units:
• One Cisco UBR-RFSW-ADV replaces two uBR 3x10 RF Switch units.
• UCH type connectors allow easy cabling and improved RF and electromagnetic interference (EMI)
performance.
• Image upgrade is improved.
• RF path performance is improved with significantly less insertion loss.
• 54 to 1002 MHz downstream frequency range.
• 5 to 85 MHz upstream frequency range.
• Fully-redundant control ports.

Interface Overview
This section describes the PRE AUX port interface on the Cisco CMTS router and its impact on the
Cisco UBR-RFSW-ADV.
PRE AUX Port Interface
The PRE AUX port is an RS-232 serial port with an RJ-45 style connector provided on all PRE cards shipped
with the Cisco uBR10012 router. It is available on the primary PRE as well as the secondary PRE. It is located
next to the console port on the PRE. If the AUX port is not used to control the Cisco UBR-RFSW-ADV, it
may be used as an alternate console connection to the PRE.

OL-24104-01
Introduction
PRE AUX Port Interface
The AUX port is used to interface with the Cisco UBR-RFSW-ADV. All commands are executed from the
PRE using this AUX serial interface. A command-control model is used where the PRE serves as a master
and the Cisco UBR-RFSW-ADV as the slave. All Cisco UBR-RFSW-ADV-related control operations and
status collection operations are initiated by the PRE. The PRE sends commands to the Cisco UBR-RFSW-ADV
over the RS-232 cable, using a proprietary protocol. The Cisco UBR-RFSW-ADV then responds with status
information.

General Safety Guidelines
General Safety Guidelines
When you install any component in a chassis, observe all caution and warning statements mentioned in this
chapter. For warning translations, see the regulatory compliance and safety documentation that came with
this product.
The following guidelines will help ensure your safety and protect the equipment. However, these guidelines
may not cover all potentially hazardous situations you may encounter during system installation, so be alert.
• Install your product in compliance with the national and local electrical codes. In the United States, this
means the National Fire Protection Association (NFPA) 70, United States National Electrical Code. In
Canada, Canadian Electrical Code, part I, CC22.1. In other countries, International Electrotechnical
Commission (IEC) 364, part 1 through part 7.
• Review the safety warnings listed in the regulatory compliance and safety documentation before installing,
configuring, or performing maintenance on the product.
• Disconnect power at the source before you install or remove a chassis.
• Do not attempt to lift an object you might find too heavy to lift safely.
• Keep the chassis area clear and as dust free as possible during and after installation.
• Keep tools and chassis components away from walk areas.
• Do not wear loose clothing, jewellery (including rings and chains), or other items that could get caught
in the chassis.
• Use the product in accordance with its marked electrical ratings and product usage instructions.
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly handled,
and can result in complete or intermittent failures. All line cards consist of a printed circuit card that is fixed
in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of
the carrier. Although the metal carrier helps to protect the cards from ESD, use an antistatic strap each time
you handle the modules. Handle the carriers by the edges only; never touch the cards or connector pins.
Caution
Always tighten the captive installation screws on all system components when you are installing them.
These screws prevent accidental removal of the module, provide proper grounding for the system, and
help to ensure that the line card connectors are properly seated in the backplane. Captive screws should
be torqued to 6-8 in-lbs to ensure proper grounding and mechanical support. Never use cordless or corded
drills to tighten screws; power screwdrivers and hand tools are acceptable.

OL-24104-01
Preparing for the Cisco UBR-RFSW-ADV Installation
Chassis-Lifting Guidelines
Static electricity can harm delicate components inside your system. To prevent static damage, discharge static
electricity from your body before you touch any of your system components. As you continue to work on
your system, periodically touch an unpainted metal surface on the computer chassis.
The following guidelines can prevent ESD damage:
• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before
removing a card from the chassis, connect the equipment end of the strap to the ESD plug at the bottom
of the chassis below the power entry modules. Ensure that the chassis or rack or both have a grounding
cable installed.
• Handle line cards by the faceplate and carrier edges only; avoid touching the card components or any
connector pins.
• When removing a card, place the removed module component-side-up on an antistatic surface or in a
static-shielding bag. If the module will be returned to the factory, immediately place it in a static-shielding
bag.
• Avoid contact between the modules and clothing. The wrist-strap protects the card from ESD voltages
on the body only; ESD voltages on clothing can still cause damage.
• When transporting a sensitive component, first place it an antistatic container or packaging.
• Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench
pads.
Caution
For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohms.
Chassis-Lifting Guidelines
This equipment is not intended to be moved frequently.
Warning
Note
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using
the handles on modules (such as power supplies, fans, or cards); these types of handles are not
designed to support the weight of the unit.Statement 1032.
This chassis is not intended to be depopulated at any time.
This chassis is a single person installable device.
When moving the equipment, use the following guidelines to prevent injury and damage to the equipment:
• Before you install the chassis, ensure that your site is properly prepared so you can avoid having to move
the chassis later to accommodate power sources and network connections.
• Because of the size and weight of the chassis, ensure that you safely lift and move the chassis without
causing injury or damaging the equipment.
• Ensure that your footing is solid, and that you balance the weight of the chassis between your feet.

Preparing for the Cisco UBR-RFSW-ADV Installation
Electrical Safety
• Lift the chassis slowly; never move suddenly or twist your body as you lift.
• Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis,
bend at the knees, not at the waist, to reduce the strain on your back muscles.
• Always disconnect all external cables before lifting or moving the chassis. In particular, verify that all
power to the chassis has been removed. Do not try to move a chassis that is connected to power or that
is powered on.
Electrical Safety
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last.Statement 1046.
Warning
Do not work on the system or connect or disconnect cables during periods of lightning
activity.Statement 1001.
Warning
Read the installation instructions before you connect the system to its power source.Statement 1004.
All system components are hot-swappable. They are designed to be removed and replaced while the system
is operating without presenting an electrical hazard or damage to the system.
Follow these basic guidelines when you are working with any electrical equipment:
• Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off
switch for the room in which you are working.
• Disconnect all power and external cables before moving a chassis.
• Do not work alone in potentially hazardous conditions.
• Never assume that power has been disconnected from a circuit; always check.
• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension
cables, and missing safety grounds.
Cisco UBR-RFSW-ADV—Site Requirements
This section provides information about environmental, power, cabling, and rack-mounting requirements. Be
sure that you have met all of these requirements before you install your product.
Cisco uBR Advanced RF Switch Hardware Installation Guide
22
OL-24104-01
Preparing for the Cisco UBR-RFSW-ADV Installation
Environmental Site Requirements
Warning
This unit is intended for installation in restricted access areas. A restricted access area can be
accessed only through the use of a special tool, lock and key, or other means of security. Statement
1017.
Environmental Site Requirements
To ensure normal operation and avoid unnecessary maintenance, plan your site configuration and prepare
your site before installation. After installation, make sure the site maintains an ambient temperature of 32
degrees F through 104 degrees F (0 degrees C through 40 degrees C), and keep the area around the equipment
as free from dust as is practical.
Planning a proper location for your equipment and the layout of your equipment rack or wiring closet is
essential for successful system operation. Maintain a minimum clearance of 5 inches (12.7 cm) on the front
and the rear of the Cisco uBR10012 chassis for cooling air and cable management.
Avoid placing the chassis in an overly congested rack or directly next to another equipment rack; otherwise,
the heated exhaust air from the other equipment can cause a high temperature condition inside the equipment.
In addition, chassis panels made inaccessible by poor equipment placement can make system maintenance
difficult. When you plan the location and layout of your equipment rack or wiring closet, you need to consider
how air flows.
In addition, allow for a minimum of 5 inches (12.7 cm) for cabling bend radii and approximately 3 to 4 ft
(91.44 cm to 121.92 cm) clearance at the front and rear of the chassis for cabling and normal system
maintenance.
To avoid problems during installation and ongoing operation, follow these general precautions when you plan
the equipment locations and connections:
• Use the show hccp channel-switch version command regularly to check the internal system status. The
environmental monitor continually checks the interior chassis environment; it provides warnings for
high temperature and creates reports on any occurrences. If warning messages are displayed, take
immediate action to identify the cause and correct the problem.
• Keep the Cisco UBR-RFSW-ADV off of the floor and out of areas that collect dust.
• Follow ESD prevention procedures (see Preventing Electrostatic Discharge Damage, on page 20) to
avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment
failure.
Temperature and Humidity Requirements
The table below lists the operating and nonoperating environmental site requirements. The ranges listed are
those within which the Cisco UBR-RFSW-ADV continues to operate; however, a measurement that is
approaching the minimum or maximum of a range indicates a potential problem. You can maintain normal
operation by anticipating and correcting environmental anomalies before they approach a maximum operating
range.

Power Guidelines
Warning
This product requires short-circuit (overcurrent) protection, to be provided as part of the building
installation. Install only in accordance with national and local wiring regulations.Statement 1045.
Warning
A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.Statement
1022.
For the AC input, the plug on the power supply cord is the disconnect device. The socket-outlet should be
installed near the equipment and should be easily accessible.
For the DC input, a readily accessible two-pole disconnect device in the fixed wiring is the disconnect device.
Follow these precautions and recommendations when planning power connections to the
Cisco UBR-RFSW-ADV:
• Check the power at your site before installation and periodically after installation to ensure that you are
receiving clean power. Install a power conditioner if necessary.
• Provide proper grounding to avoid damage from lightning and power surges.
• Use a 6-AWG (for NEBS-compliant grounding), copper ground conductor (minimum requirement)
when attaching the chassis ground to a central office or other interior ground system.

OL-24104-01
Preparing for the Cisco UBR-RFSW-ADV Installation
Plant Wiring Guidelines
Power Connection Guidelines for DC-Powered Systems
The DC-input power supply allows the Cisco UBR-RFSW-ADV to operate on either –48 or –60 VDC systems.
For system power specifications, including input voltage and operating frequency ranges, see Power
Requirements, on page 119
Warning
Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV)
requirements in IEC 60950 based safety standards.Statement 1033.
Plant Wiring Guidelines
When planning the location of the new system, consider the distance limitations for signaling, EMI, and
connector compatibility, as described in the following sections.
Warning
This product requires short-circuit (overcurrent) protection, to be provided as part of the building
installation. Install only in accordance with national and local wiring regulations.Statement 1045.
Interference Considerations
When wires are run for any significant distance in an electromagnetic field, interference can occur between
the field and the signals on the wires. This fact has two implications for the construction of plant wiring:
• Bad wiring practice can result in radio interference emanating from the plant wiring.
• Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers
and receivers in this equipment, and can even create an electrical hazard by conducting power surges
through lines and into equipment. (Review the safety warnings in the Preventing Electrostatic Discharge
Damage, on page 20.)
Note
To predict and remedy strong EMI, you may also need to consult experts in radio frequency interference
(RFI).
If wires exceed recommended distances, or if wires pass between buildings, give special consideration to the
effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy
phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you
have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and
shielding.
Cabling Guidelines
The size of your networks and the distances between connections depend on the type of signal, the signal
speed, and the transmission media (the type of cabling used to transmit the signals). For example, standard
coaxial cable has a greater channel capacity than twisted-pair cabling. The distance and rate limits in the
following descriptions are the IEEE recommended maximum speeds and distances for signaling; however,
you can usually get good results at speeds and distances far greater than these. For example, the recommended
Cisco uBR Advanced RF Switch Hardware Installation Guide
OL-24104-01
25
Preparing for the Cisco UBR-RFSW-ADV Installation
Rack-Mounting Considerations
maximum rate for V.35 is 2 Mbps, but it is commonly used at 4 Mbps without any problems. If you understand
the electrical problems that might arise and can compensate for them, you should get good results with rates
and distances greater than those shown here; however, do so at your own risk.
When preparing your site for network connections to the chassis, you must consider a number of factors
related to each type of interface:
• Type of cabling required for each type (fiber, thick or thin coaxial, foil twisted-pair, or unshielded
twisted-pair cabling)
• Distance limitations for each signal type
• Specific cables you need to connect each interface
The extent of your network and the distances between network interface connections depend in part on the
following factors:
• Signal type
• Signal speed
• Transmission medium
Rack-Mounting Considerations
The Cisco UBR-RFSW-ADV should be rack-mounted for proper operation and maintenance. The rack-mounting
hardware included with the chassis is suitable for standard four-post, 19-inch (48.26 cm) equipment racks.
Mounting Guidelines
Warning
The chassis should be mounted on a rack that is permanently affixed to the building.Statement 1049.
When planning your rack installation, consider the following guidelines:
• Install the Cisco UBR-RFSW-ADV in an open rack whenever possible.
Caution
To prevent overheating, never install the chassis in an enclosed rack or room that is not properly ventilated
or air conditioned.
• Allow sufficient clearance around the rack for maintenance. You need 24 in. (61 cm) of clearance to
remove and replace system components.
Caution
To prevent the rack from tipping when installing the switch, ensure that the rack is bolted to the floor and,
if necessary, anchored with appropriate fixtures.

Tools for Installation
Note
The reference design does not include the two-post telco rack-mounting option, and the suggested or
recommended cables may not reach or be adequate for this mounting design. Although, mounting holes
are located in the center of the chassis and an offset grounding lug is also provided for a center or mid-mount
scenario, it is not a recommended option to center mount the Cisco UBR-RFSW-ADV with the Cisco
uBR10012 chassis.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
unit in the rack.
• To mount the chassis between two 19-inch posts or rails, the inner clearance (the width between the
inner sides of the two posts or rails) must be at least 17.5 in. (44.5 cm).
• When mounting the chassis in 4-post 19-inch racks, be sure to use all the screws and brackets provided
to secure the chassis to the rack posts.
• Install the forward rack-mount brackets before you install the chassis in the rack; and then install the
rear brackets.
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment
in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable grounding is available.Statement 1024.

Rack-Mounting the Cisco UBR-RFSW-ADV
Mounting Two Cisco uBR10012 Universal Broadband Routers and Two Cisco UBR-RFSW-ADVs in a Single Rack
Cable-management brackets help in routing cables. The RF cables, on both sides of the Cisco UBR-RFSW-ADV
are routed in both, vertical and horizontal directions and tied to either side of the rack.
Mounting Two Cisco uBR10012 Universal Broadband Routers
and Two Cisco UBR-RFSW-ADVs in a Single Rack
The size of a Cisco UBR-RFSW-ADV when it does not include the optional Cisco UBR-RFSW-ADV cable
management system (that takes up 1 to 2 rack units [RU] depending on cable routing requirements) is 3 RU.
Hence, in a single rack, you can mount two Cisco UBR-RFSW-ADV and two Cisco uBR10012 routers.

describes how to remove and replace the field-replaceable units (FRUs) in the Cisco uBR Advanced RF
Switch (Cisco UBR-RFSW-ADV).
• Field Upgrades, page 47
• How to Remove and Install the FRUs, page 48
Field Upgrades
The Cisco UBR-RFSW-ADV supports field upgrades for both the operating software image and FRUs. It
handles system management of field upgrades, like hot swapping cards and micro-controller images. The
Cisco uBR10012 router initiates image download and facilitates access to the Cisco UBR-RFSW-ADV.
Software Upgrades
The Cisco UBR-RFSW-ADV supports online software image upgrades. The operating state (failover,
pass-through) is not changed during the download or upgrade process. The interface between the controller
card and the Cisco uBR10012 router via the RS-232 interface is functional during the image upgrade process.
Hardware Upgrades
All FRUs in the system are field-upgradable. The Cisco UBR-RFSW-ADV is responsible for managing all
image updates to the individual system cards. All cards support hot-swapping.
The following FRUs are present in the Cisco UBR-RFSW-ADV:
• Upstream switch cards
• Upstream protect cards

page 90
• Connecting the RF Cables From the Cisco UBR-RFSW-ADV to the Cable Plant, page 91
• Connecting the PRE With the Controller Card, page 91
Protection Scheme for the Cisco uBR10012 Router
The N+1 redundancy protection scheme you select for your system depends largely on the number and type
of cable interface line cards you have installed in your Cisco uBR10012 router. The 7 + 1 eight-card redundancy
scheme supports redundancy among the cable interface line cards installed in a fully populated Cisco uBR10012
router.
Note
The default protect line card slot in the Cisco uBR10012 router is subslot 5/1. However, you can configure
subslot 7/1 as the protect line card to better align the cables because this slot is directly below the PROTECT
section on the Cisco UBR-RFSW-ADV.
The protect cards slots are in the middle of the Cisco UBR-RFSW-ADV.

Connecting the RF Cables From the Working and Protect Line
Cards to the Cisco UBR-RFSW-ADV
Caution
The UCH2 must be used for all cable connections to the line card. Failure to use a UCH2 may cause
permanent damage to the line card connectors, resulting in low or no RF output in the downstream or low
or no RF input in the upstream.
Note
This procedure assumes that the RF cables are already installed in the UCH and mounted on the Cisco
cable interface line card. If the cables have not been installed in the UCH2 and mounted on the line card,
see the Cisco UBR-MC20X20V Cable Interface Line Card Hardware Installation Guide, or Cisco
uBR-MC3G60 Cable Interface Line Card Hardware Installation Guide depending on the cable interface
line card installed in the Cisco uBR10012 router.
Before You Begin
Have the following tool ready before performing this task:
• Slotted screwdriver
Procedure
Step 1
Step 2
Step 3
Step 4
Position the UCH2 so that the red line is on the same side as the red line on the card.
Align the end pins on the UCH2 with the pin holes in the faceplate. (See Figure 33: Installing the UCH2 on
the Faceplate, on page 91.)
Caution
When you are replacing the UCH2, be careful not to bend the cables in the holder at right
angles.
While holding the UCH2 and cables in place on the faceplate, use your fingers to tighten the leadscrew. If the
UCH2 and cables do not appear to settle securely in place on the faceplate, wiggle the holder to resettle the
connectors.
Use the slotted screwdriver to tighten the leadscrew. Turn the leadscrew clockwise until it can no longer turn
(10 in-lbs, maximum torque 15 in-lbs).
Caution
Torquing the leadscrew to more than the maximum of 20 in-lbs can cause the leadscrew to
fail.

Connecting the RF Cables From the Cisco UBR-RFSW-ADV to the Cable Plant
Note
As you turn the leadscrew clockwise, the outer shroud on the UCH2 moves to cover the red line on
the top and the black line on the bottom of the UCH2. The half circles on the edge of the shroud
appear to close as the shroud fits down over the UCH2. Full engagement is indicated by visible
metal-to-metal contact between the UCH2 and the faceplate (check the half circle cutouts).
Figure 33: Installing the UCH2 on the Faceplate
Step 5
Repeat Step 1 through Step 4 for the other two UCH2s.
Caution
To ensure proper installation and avoid poor connections, be sure that the cables are not positioned
at too acute an angle.

Powering the Cisco UBR-RFSW-ADV
This chapter explains the procedures to connect the power supply on the Cisco Next Generation RF Switch
Advanced (UBR-RFSW-ADV).
Warning
Before working on equipment that is connected to power lines, remove jewelry (including rings,
necklaces, and watches). Metal objects will heat up when connected to power and ground and can
cause serious burns or weld the metal object to the terminals. Statement 43.
Warning
This equipment is intended to be grounded to comply with emission and immunity requirements.
Ensure that the switch functional ground lug is connected to earth ground during normal use.
Statement 1064
Warning
This unit might have more than one power supply connection. All connections need to be removed
to de-energize the unit. Statement 1028
Before connecting power and turning on the Cisco UBR-RFSW-ADV, you must provide an adequate ground
connection for your system. Then see the following sections:
• Grounding the Cisco UBR-RFSW-ADV, page 95
• Connecting AC Power to the Power Supply, page 97
• Connecting DC Power to the Power Supply, page 99
• Powering On the Cisco UBR-RFSW-ADV, page 101
• Power Supply LED Behavior, page 101
Grounding the Cisco UBR-RFSW-ADV
Before connecting power and turning on the Cisco UBR-RFSW-ADV, you must provide an adequate ground

Before You Begin
Warning
Before performing any of the following procedures, ensure that power is removed from the DC
circuit. Statement 1003.
Warning
A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement
1022.
Warning
This product requires short-circuit (overcurrent) protection, to be provided as part of the building
installation. Install only in accordance with national and local wiring regulations. Statement 1045.
Caution
Each DC-input current is less than 1.8 A continuous and power is 30 W. Use a minimum of 14 AWG (2.5
mm²) wire for the input to each DC-input power supply. The power input must be protected by a 15 A
circuit breaker or fuse that is in compliance with your local electric regulations.
Note
The color coding of the DC-input power supply leads depends on the color coding of the DC power source
at your site. Typically, green or green-yellow is used for ground, black is used for +48 V (return), and red
or white is used for –48 V. Ensure that the lead color coding you choose for the DC-input power supply
matches lead color coding used at the DC power source.
Have the following tools ready before you perform this task:
• 14 AWG (2.5 mm2) wire
• 1/8-inch flatblade screwdriver
• Wire stripper
• AC to DC power source

Note
Blue
Indicates that the lower five ports are in protect mode.
Red
Alarm condition.
Only the upper LED is used for downstream switch cards.
Each upstream switch card has two LEDs and each downstream switch card has one LED to indicate the
working status of the port. The upstream switch module operates over the frequency range of 5 MHz to 85
MHz. The downstream (high-frequency) switch module operates over the frequency range of 54 MHz to 1002
MHz. During normal system operation, upstream switches all direct traffic to their respective default termination
interfaces.
The switch card should provide a minimum of 65 dB of isolation from connector port to connector port during
normal operation and more than 65 dB when operating in protect mode.
When an upstream or downstream switch module initially boots, the LEDs briefly cycle on in sequence.
