Maintaining the Air Filter

Action

To maintain the air filter on M40, M40e, M160, and T320 routers and T640 routing nodes, follow these steps:

1. Check the air filter for dust, debris, or holes. If the air filter needs cleaning, clean it as described in the appropriate hardware guide.
2. If the air filter needs repair, replace it as described in the appropriate hardware guide.
   

   CAUTION: Because the impellers and fans are quite powerful, it is important to keep the air filter in place while the router is operating. The impellers and fans could pull in foreign material, such as bits of wire, through an unfiltered air intake, resulting in damage to router components.
