The chassis has a serviceable air filter mounted in a slide-out tray accessible from the front of the chassis just
below the lower card cage (as shown in the figure). The air filter removes dust from the room air drawn into
the router by the two fan trays. Once a month (or more often in dusty environments) you should examine the
air filter and replace it if it appears damaged or excessively dirty.
