Installation and safety considerations

Electrical considerations

To install and operate the switch successfully, ensure the following:

• 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 Table 6, “Power Supply Specifications” on

page 28 are met.

Environmental considerations

For successful installation and operation of the switch, ensure that the following environmental

requirements 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 maximum of 102 cubic meters/hour (60 cubic feet/minute) and a minimum of 74.8

cubic meters/hour (44 cubic feet/minute) 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° C (104° F) while the switch is operating.

Cabinet considerations

For successful installation and operation of the switch in a cabinet, ensure the following cabinet

requirements are met:

• The cabinet must be a standard EIA cabinet.

• Plan a cabinet space that is one rack unit (1U) high; 4.45 cm (1.75 inches) high and 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.

Recommendations for cable management

The minimum bend radius for a 50 micron cable is 2 inches under full tensile load and 1.2 inches

with no tensile load.
