4Cisco 7000 Air Filter and Chassis Blower Replacement Instructions
Caution:
Operate the system only if the blower is installed and functioning properly.
The blower prevents an overtemperature condition that can result in severe equipment
damage.
The air filter fits into the lower frame of the top front chassis panel (see Figure 3).
Maintaining a consistent air filter cleaning schedule helps to maintain normal system
operation. A dirty filter can prohibit the flow of cooling air into the chassis and may
cause an overtemperature condition.
You need only remove the bottom front chassis panel to access the filter. Although you
should not operate the system for more than a minute without the filter in place, you
can briefly remove the filter to vacuum it and immediately replace it. Vacuuming the
filter while it is still in the panel is likely to dislodge dust particles into the chassis interior.
You can also remove the filter and wash it in warm water, and replace it when it is
completely dry. While the filter is drying, install a spare filter or shut down the system.
