Environments
C6CHASSI S
SYSTEMS ENGINEERED TO PERFORM®
The M2U-20A is designed to survive! Aircraft grade
alum inum construction, shock m ounted unibody drive
support, self locking stainless hardware, solid
construction, designed and m anufactured in the USA.
These system are ideal for high shock / high vibration
environm ents such as vehicular or aircraft m ount or
transit case installation. The short depth of 20 inches
allows it to fit virtually all transit cases. The rugged
construction and enhanced features will assure its
reliable operation in that challenging environm ent.

M2U-20A RUGGED MIL GRADE 2U ENCLOSURE
Prim ary construction is from high strength
aircraft grade .090-inch 5052-H32 alum inum alloy. The front panel is m illed from a
single piece of .250-inch alum inum . A
form ed and welded alum inum door covers
the drives and supports the air filter. An
integrated system is very light at only 2224 lbs depending on installed com ponents.
At only 20-inches deep, this m akes the
M2U-20A perfect for transit case installations.
System controls are m ounted behind the front
door and include power control, system reset,
and alarm reset. Mounted in the front panel is
the Power-on LED, HDD Access, Fan Failure
and Overtem p and 2 LAN LEDs. Two USB ports
are also provided behind the front door. Custom control and indicator configurations are
easily accom m odated.
For environm ental and em issions protection, the front panel provides an em bedded
EMI / environm ental gasket and m ultiple
captive fasteners on the door to secure the
system from contam ination.
A key feature for system survivability is the
use of 2-1/ 2” drives. Either standard hard
drives or Solid State Drives ( SSD) can be
installed. Both types offer exceptional survivability with the SSD type being virtually
indestructible. Rem ovable drives can be
populated. Also provided is a slim DVD
and floppy drive.
The overall effect is a very robust enclosure to protect the system in any foreseeable environm ental challenge.
Cooling is provided by three 80x38m m
high flow fans providing 80CFM each of
high pressure air flow. The front door is
provided with an easily serviced and washable air filter with various classes available.
A chassis over- tem perature alarm and fan
failure circuit m onitors chassis conditions.
Optional higher velocity fans and fan speed
control is available.
