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.
