Removing and Replacing the Air Filters
The Cisco XR 12406 router is equipped with two user-serviceable air filters that
remove dust drawn into the router by the blower module. You should examine the
air filters once a month (or more often in dusty environments). If the filter appears
dirty, you can either vacuum or replace it. If the filter appears worn or torn,
dispose of it in a responsible manner and install a replacement air filter.
Use the following procedure to clean or replace the air filters.
Step 1 Open the spring-loaded air filter door on the right side of the chassis and remove
an air filters by pulling the small tab on the edge of the filters (see
Figure 5-2 ).
Step 2 Visually check the condition of the air filters.
• If the filters appears dirty, you can either vacuum or replace them.
Caution Do not vacuum the air filter while it is installed in the housing.
• If the filters appear worn or torn, dispose of them in a responsible manner and
install replacement air filters.
