The Cisco 12016 series routers are equipped a user-serviceable air filter that 
removes dust drawn into the router. One time per month (or more often in dusty 
environments), examine the air filter for damage and cleanliness.

Damage to the air filter can restrict the airflow, cause overheating in the router, 
and degrade EMI performance. Be careful when cleaning and replacing the filter.

The following procedures describe how to replace the air filter on original series 
routers and enhanced series routers.
