About Line Card Chassis Airflow

Figure 3-1

Airflow Through the Cisco CRS 4-Slot Line Card Chassis

A replaceable air filter is located inside the chassis below the PLIM card cage at an angle. In addition,
there is a removable air filter on the front of the power tray air intake grille on the front (PLIM) side of
the chassis. (See

Figure 3-2

.)

Air Filter Replacement Frequency Recommendation

How often the air filters should be replaced depends on the facility environment. In a dirty environment,
or when you start getting frequent temperature alarms, you should always check the intake grilles for
debris, and then check the air filters to see if they need to be replaced.
