Installation and safety considerations
2
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 5 , “Power Supply Specifications” on page 29 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 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 page 26 for more information
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

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 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.
