Figure 2-2a shows a free-standing, enclosed rack with two mounting posts in the
front. The router should not be installed in this type of enclosed rack, because the
router requires an unobstructed flow of cooling air to maintain acceptable
operating temperatures for its internal components. Installing the router in any
type of enclosed rack—even with the front and back doors removed—could
disrupt the air flow, trap heat next to the chassis, and cause an overtemperature
condition inside the router.
Figure 2-2b shows a free-standing, 4-post open rack with two mounting posts in
the front and two mounting posts in the back. The mounting posts in this type of
rack are often adjustable so that you can position the rack-mounted unit within the
depth of the rack rather than flush-mount it with the front of the rack.
