System Installation
Most of the system plug-in cards have highly sensitive components that could be damaged by
static electricity. Whenever you handle any system cards, be sure to observe local electrostatic
discharge (ESD) precautions.
The mounting brackets supplied with the chassis are needed for tabletop installation. The top
and bottom of each chassis also must be clear of objects to ensure proper air flow through the
chassis.
The system chassis can be installed on an 19-inch or 23-inch equipment rack, attached to a
wall, or placed on a tabletop or other level surface. First though, make sure the desired surface
can support the weight of a fully equipped chassis.
The system specifications section in this manual lists the maximum power consumption of
each system card. Use this table to calculate the total system power consumption.
The system specifications section in this manual also lists some typical current measurements
for each card at all DC operating voltages.
Be sure to locate the system near all external equipment to which you will connect it. Cable
lengths and physical/electrical characteristics are critical to system operation, especially for
data signal interfaces. Generally, higher data rates require shorter cables than lower data rates.
Also, you must use E1-grade cables for all system connections to those networks. For best
results, use the cables supplied by your supplier when connecting your system to the
associated external facilities. For more information on system cabling, call your supplier.

Rack Installation Tips

When installing the chassis in a rack, allow at least 2 inches (5.1 cm) of space between the
chassis and the equipment above and below it for proper ventilation. Use the mounting
brackets and attachment hardware furnished with the chassis for this purpose, as outlined in
the next section. If you use other mounting hardware, you may damage the chassis or circuit
boards installed in it.
Also route all cables to their destinations through conduits to enhance electromagnetic
compatibility (EMC) performance and facilitate future system troubleshooting. When routing
cables, be sure not to obstruct any chassis vents.

Wall-Mount Installation Tips

To mount the chassis on a wall, first obtain a piece of standard, marine-grade plywood (3/8
inch diameter, typical) and bolt it firmly to the desired mounting surface. This board must be
long and wide enough to cover the entire chassis length and height. The surface must be able
to support the total weight of the system (chassis plus plug-in cards).
