AND
CONNECTIONS
CORRECT GROUNDING PROTECTION IS REQUIRED – Connect the ground studs,
located on the rear panel of the components, to a power system that has separate
ground, line and neutral conductors. Do not operate the system without a direct
connection to ground.
The rack must be connected to a suitable earthing connection at all times. You must
connect the rack ground bar to a suitable earthing demarcation point.
CORRECT AIR VENTILATION IS REQUIRED – In a rack system where there is high heat
discharge, provide forced-air cooling with top- or bottom-mounted fans or blowers.
Make sure there is adequate clearance inside the enclosure, especially at the sides, for
air circulation and ventilation.
Air temperature inside the rack enclosure should never exceed 50
°
C (122
°
F).
If there is any doubt, contact Comtech EF Data Product Support during normal
business hours.
Figure 4-2 shows an example of a complete CRS-500 1:N Redundancy System rack configuration.
The standard CRS-500 CSU is constructed as a 1RU-high, rack-mounting chassis that may also
be free standing. Rack handles are provided to facilitate removal and placement into a rack.
Install the CSU, using the front panel mounting holes
only, into the front of the rack.
The standard CRS-500 DSU mounts into the back or on top of the rack in one of four
configurations. As shown in Figure 4-3 and Figure 4-4, the user can use the KT-0000072
CRS-500 DSU Rack Mounting Kit (Figure 4-5) to install the DSU module as needed, positioning
or hinging the unit outward to permit convenient access to the RMIs/TMIs for cable connections
between the DSU, CSU, ISU, and the modems.
Mount the optional CRS-280/280L ISU into the back or on top of the rack.
Once you install all CRS-500 1:N Redundancy System components, the configuration is now ready
to be interconnected as specified in
