2.2 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.
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
°
C
(122
°
F).
