Removing and Replacing the Air Filter
The Cisco ASR 9001 Series Router, when used with the air plenum, has a serviceable air filter (Cisco PID
ASR-9001-PLNMFLTR=) that is accessible from the top of the of the air filter assembly (see the following
figure). The air filter removes dust from the room air drawn into the chassis by the fan trays.
Regularly check the air filter at least every three months. If used in a dusty environment, check the air filter
once a month. Replace it if it appears excessively dirty or damaged. Failure to replace a compromised air filter
can result in insufficient air circulation through the chassis.
To comply with Telecordia GR-63-Core standard air filter requirements for NEBS deployments, the air
filter must be replaced.
Note
The air filter can be removed from the air plenum assembly without removing the cables or the fan tray.Note
