Cleaning and Replacing the Air Filter Assembly
Cleaning the Air Filter
Perform the following steps clean the air filter with a vacuum cleaner:
Step 1
Move the air filter away from the lower card cage opening.
Step 2
Vacuum the surface of the filter thoroughly.
Caution
Do not vacuum the filter while it is installed or near the lower card cage opening;
doing so can dislodge substantial amounts of dust, which could be drawn into the card cage
assembly. Never wash a filter and install it in the system. Moisture drawn into the system
can damage the components.

Removing the Old Air Filter Assembly
The following procedure guides you through the removal of the old air filter assembly.
Caution
To prevent damage, do not place any tools on the air filter tray or inside the card
cage. Laying tools inside either the card cage or on the air filter tray could restrict the air
flow and cause an overtemperature condition in the Cisco 12012.
Warning
There might be exposed line or fabric cards. Extreme caution is advised when
working around an open card cage.
Step 1
Set the old air filter aside.
