Environmental considerations

For successful installation and operation of the switch, ensure that the following environmental
requirements are met:

Cabinet considerations

For successful installation and operation of the switch in a cabinet, ensure the following cabinet
requirements are met:

Recommendations for cable management

The minimum bend radius for a 50 micron cable is 5.08 cm (2 inches) under full tensile load and
3.05 cm (1.2 inches) with no tensile load.
Cables can be organized and managed in a variety of ways: for example, using cable channels on
the sides of the cabinet or patch panels to minimize cable management. Following is a list of
recommendations:
6
The primary outlet is correctly wired, protected by a circuit breaker, and grounded in
accordance with local electrical codes.
The supply circuit, line fusing, and wire size are adequate, as specified by the electrical rating
on the switch nameplate.
The power supply standards provided in
on page 24 are met.
•
At a minimum, adequate cooling requires that you install the switch with the non-port side,
which contains the air intake vents, facing the cool-air aisle.
•
All equipment in the rack should force air in the same direction to avoid intake of exhaust
air.
•
A minimum of 30.6 cubic meters/hour (18 cubic ft/min) and a maximum of 39.1 cubic
meters/hour (23 cubic ft/min) of air flow is available to the air intake vents on the non-port
side of the switch.
•
The ambient air temperature does not exceed 40
•
The cabinet must be a standard EIA cabinet.
•
Plan a cabinet space that is 1 rack unit - 4.45 cm (1.75 inches) high, 48.3 cm (19 inches)
wide.
•
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.
•
Ensure that airflow and temperature requirements are met on an ongoing basis,
particularly if the switch is installed in a closed or multicabinet assembly.
•
Verify that the additional weight of the switch does not exceed the cabinet's weight limits
or unbalance the cabinet in any way.
•
Secure the cabinet to ensure stability in case of unexpected movement, such as an
earthquake.
