Removing the Air Filter

This section describes removing the air filter. The air filter is located in the bottom of the chassis behind the plastic grill.


Note

The Cisco NCS 4009 chassis can have two types of air filters, depending on the fabric cards it houses.

  • If the installed fabric card is, NCS4009-FC2-S, the air filter is NCS4009-FTF.

  • If the installed fabric card is, NCS4009-FC2F-S, the air filter is NCS4009-FTF-2.

The air filter prevents dust from the air in the room, to be drawn into the chassis by the fan tray. If it is damaged, dirty, or clogged with dust, they must be replaced with a new air filter. Failure to replace a compromised air filter can result in insufficient air circulation through the chassis and temperature-related environmental alarms.


Caution

Never operate the Cisco NCS 4009 chassis without an air filter. Operating a Cisco NCS 4009 chassis without a filter for an extended time can result in damage to the chassis hardware.


Note
