Installing the Air Plenum Kit in an ETSI Two-Post to Four-Post Rack
The air plenum kit is assembled and mounted in the rack before the Cisco ASR 9001 Router is installed.
Note
To install the air plenum kit in an ETSI four-post open rack, follow these steps:
Procedure
Step 1 Place the plenum base on a flat and stable surface. Secure the left and right adapter plates to the front of the
plenum base using two Cisco supplied M5x10mm screws rack-mounting screws in the top and bottom screw
holes on the plenum base.
Step 2 Attach the left and right air baffles to the plenum base using the Cisco supplied M5x10mm screws (four for
each air baffle). The keyholes on each side of the plenum base will help to guide the air baffles into position
