Requirements
v A minimum air flow of 53 cubic meters per
hour (31 cubic feet per minute) available
in the immediate vicinity of the router
v Ambient air temperature not exceeding
40°C (104°F) while the router is operating
v A minimum of 5.1 cm (2 in.) airspace for
air intake and exhaust vents
v If cabinet mounted, install the router with
the nonport side, which contains the air
intake vents, facing the cool-air aisle.
v Ensure that airflow and temperature
requirements are met on an ongoing
basis, particularly if the router is installed
in a closed or multi-cabinet assembly.
v A minimum of one EIA unit high in a 19-in.
(48.3 cm.) cabinet.
v Ground all equipment in the cabinet
through a reliable branch circuit
connection and maintain ground at all
times. Do not rely on a secondary
connection to a branch circuit, such as a
power strip.
v Verify that the additional weight of the
router does not exceed the cabinet's
weight limits or unbalance the cabinet in
any way.
v Cabinet must be secured to insure stability
in case of unexpected movement, such as
an earthquake.
v Plan for cable routing and management
before installing the chassis. See
"Planning for cable management" on page
18 for more information. Allow at least 3U
of space below the chassis if you will be
routing cables under the chassis.
