Under normal operation, you do not need to replace the air filter. Replace the filter only when an excessive amount of dirt and dust has collected over an extended period of time, or if a module has a lit Over Temp LED. See the Cisco VPN 5002 and 5008 Module Hardware Guide for more information about resolving a high temperature condition. Cisco Systems provides an extra filter with each unit to minimize the concentrator's down time.

Complete these steps to change the filter.
Step 2 Remove 12 screws from both sides of the chassis, removing the brackets if present.
Step 3 Remove the top panel from the chassis and remove the filter from its slot.
Step 4 Put the supplied replacement filter in the slot and replace the top panel.
Step 5 Fasten the top panel and the mounting brackets, if present, to the chassis with the screws you removed in Step 2.
Step 6 Return the chassis to its mounting according to the"Rack-Mounting the Chassis" section or the "Wall-Mounting the Chassis" section.
Step 7 Wash the old filter in warm, soapy water and allow to completely dry.
You can reuse the old filter the next time you change the filter. If either of the supplied filters is worn out or cannot be thoroughly cleaned, you can order a replacement filter from Cisco Systems.
