Replacing the Air Filter
The router has one air filter that installs vertically in the rear of the chassis. The air
filter is hot-insertable and hot-removable.
The air filter is located in the rear of the chassis on the left side. The air filter weighs
approximately 1 lb (0.5 kg).

Removing an Air Filter

CAUTION: Do not run the router for more than a few minutes without the air filter
in place.
CAUTION: Always keep the air filter in place while the router is operating, except
during replacement. Because the fans are very powerful, they could pull small bits
of wire or other materials into the router through the unfiltered air intake. This could
damage the router components.
