Table 11. Facility requirements
Type Requirements
Electrical
v Primary AC input 100-240 VAC, 2.0A,
47-63 Hz; switch autosenses input voltage
v
Adequate supply circuit, line fusing, and
wire size, as specified by the electrical
rating on the switch nameplate
v
Correctly wired primary outlet, with
circuit protected by a circuit breaker and
grounded in accordance with local
electrical codes
Thermal
v
A minimum air flow of 24 cubic ft/min
available to the air intake vents on the
nonport side of the switch.
v Ambient air temperature not exceeding
40° C (104° F) while the switch is
operating
v At a minimum, adequate cooling requires
that you install the switch with the
nonport side, which contains the air
intake vents, facing the cool-air aisle
v
All equipment in the rack should force air
in the same direction to avoid intaking
exhaust air
v
Ensure that airflow and temperature
requirements are met on an ongoing basis,
particularly if the switch is installed in a
closed or multicabinet assembly
Cabinet (when rack-mounted)
v One rack unit in a standard EIA 19-in.
(48.3 cm) cabinet
v
All equipment in cabinet grounded
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 Additional weight of switch not to exceed
the cabinet’s weight limits
v Cabinet secured to ensure stability in case
of unexpected movement, such as an
earthquake
