Figure 2-2 Equipment Rack Types

Enclosed Rack

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.

Open Rack

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.
