Installing into a Rack Enclosure
The CRS‐311 is constructed as a 2RU‐high, rack‐mounting chassis. Rack handles are
provided to facilitate removal and placement into a rack. When mounting the
CRS‐311 into a rack enclosure (Figure 2‐2):
•
PROPER GROUNDING PROTECTION IS REQUIRED. The equipment must be
connected to the protective earth connection at all times. It is therefore imperative
that the setup is properly grounded – e.g., use the ground studs provided on the
modem rear panels – during installation, configuration, and operation.
•
PROPER AIR VENTILATION IS REQUIRED. The CRS‐311 CANNOT have rack slides
mounted to the sides of the chassis – air flow must not be impeded. In a rack
system where there is high heat discharge, provide forced‐air cooling with top‐
or bottom‐mounted fans or blowers.
For information about custom rack enclosures, contact Comtech EF Data
Customer Support during normal business hours or visit Comtech EF Data's Web
site (www.comtechefdata.com/support.asp).
Review the Installation and Operation Manual carefully to become
familiar with operation.
Proceed to Sect. 2.2 Installing into a Rack Enclosure.
o Make sure there is adequate clearance inside the enclosure, especially at
the sides for air ventilation.
o Air temperature inside the rack enclosure should never exceed 50
°
(122
F).
