Installation and safety considerations

Electrical considerations

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

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:
10
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
met.
•
At a minimum, adequate cooling requires that you install the switch with the cool-air intake
set to either the port or non-port side, so that the cool-air intake matches the airflow type
of the Power Supply/Fan FRU units present in the Brocade VA-40FC.
Refer to "Power supply/fan assembly FRU replacement"
on identifying the airflow type."
•
All equipment in the rack should force air in the same direction to avoid intake of exhaust
air.
•
A maximum of 49.3 cubic meters/hour (29 cubic feet/minute) and a minimum of 37.4
cubic meters/hour (22 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
•
The cabinet can be a standard EIA cabinet, or an EIA cabinet with 24" depth.
•
Plan a cabinet space that is one rack unit (1U) high; 4.45 cm (1.75 inches) 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.
