Step 2 For the Cisco ASR 9922 Router and Cisco ASR 9912 Router, remove the three air filters by pulling them off
the front of the chassis (Cisco ASR 9922 Router Chassis Air Filters) and (Cisco ASR 9912 Router Chassis
Air Filter ). Then, for each filter, loosen the thumb screws, rotate the inner frame out, and replace the foam
media (Removing the Cisco ASR 9922 Router Chassis Center Air Filter—Version 1 and Removing the Cisco
ASR 9922 Router Chassis Side Air Filter —Versions 1 and 2).
In the Cisco ASR 9922 Router (version 2 air filter) the center air filter, shown in Cisco ASR 9922
Router Chassis Center Air Filter—Version 2, does not contain replaceable foam media. The left
and right air filters are the same as version 1 and contain replaceable foam media.
