Rack Installation Safety Guidelines
The Cisco ADE 2130 and 2140 Series appliance can be mounted in most 2-post, 4-post, or telco-type
19-inch equipment racks that comply with the Electronics Industries Association (EIA) standard for
equipment racks (EIA-310-D). The rack must have at least two posts with mounting flanges to mount
the appliance. The distance between the center lines of the mounting holes on the two mounting posts
must be 18.31 inches +/- 0.06 inch (46.50 cm +/- 0.15 cm). The rack-mounting hardware included with
the appliance is suitable for most 19-inch equipment racks or telco-type frames.
Figure 2-1 shows examples of 4-post and 2-post (telco-type) equipment racks, respectively.
Figure 2-1 Equipment Rack Types
Enclosed Rack (Do Not Use)
Figure 2-1a shows a free-standing, enclosed rack with two mounting posts in the front. The
Cisco ADE 2130 and 2140 Series appliance should not be installed in this type of enclosed rack, because
the appliance requires an unobstructed flow of cooling air to maintain acceptable operating temperatures
for its internal components. Installing the appliance in any type of enclosed rack—even with the front
and back doors removed—could disrupt the airflow, trap heat next to the appliance, and cause an
overtemperature condition inside the appliance.
4-Post (Open) Rack
Figure 2-1b shows a free-standing, 4-post open rack with two mounting posts in front and two mounting
posts in 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.
