Removing the Rear Air Plenum Covers
The cabinet contains an air plenum at the bottom of the rear compartment that provides air
flow to the rear equipment rack. Since the cabinet typically ships with no powered equipment
on the rear rack, the rear plenum is covered at the factory to keep cool air directed toward
the C7 shelf and not wasted on the rear rack.
However, if any powered equipment is to be installed on the rear rack, you must first remove
the air plenum cover to enable proper air circulation and cooling to the rear rack. Remove
the plenum cover as described below.
To remove a plenum cover
1.
Open the rear cabinet door.
2.
Swing the rear equipment rack into the open position.
3.
Using both hands, pull the plenum cover plate forward until the front lip of the cover
clears the front lip of the plenum.
4.
Lift the cover away from the plenum, taking care to disengage the two tabs on the cover
from the corresponding slots in the plenum.
5.
Discard the plenum cover or set it aside for future reuse.
