Removing and Replacing Field-Replaceable Units
This section contains procedures to remove and replace all of the field replaceable
units (FRUs) for the Cisco 10005 ESR.
Replacing the Air Filter
If the air filter is dirty or clogged, the fan assembly might not be able to provide
sufficient cooling air flow through the chassis, causing the system to overheat. To
prevent an overheating problem, replace the air filter every 6 months. In dirty or
dusty environments, replace the filter more frequently.
Note
If you want to reuse the air filter, use a vacuum cleaner to remove the dust.
The air filter is accessible from the rear of the chassis. It occupies a vertical slot
on the left side of the chassis.
To replace the air filter:
Step 1
Use a flat blade screwdriver to turn the cam fastener on the air filter cover one half
of a rotation (180 degrees) (
Figure 3-1
).
