•
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
•
Because the Brocade VDX6720 can be ordered with fans that either move air front to back
or back to front, be sure to orient your switch with the airflow pattern of any other devices
in the rack.
•
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.
•
The ambient air temperature does not exceed 40
•
The cabinet must be a standard EIA cabinet.
•
A cabinet space that is one rack unit (1U for VDX6720-24) or two rack units (2U for
VDX6720-60) high depending on the platform ordered; 4.45 cm (1.75 inches) or 8.90 cm
(3.50 inches) high and 48.3 cm (19 inches) wide.
•
The equipment in the cabinet is 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.
•
Airflow and temperature requirements are met on an ongoing basis, particularly if the
switch is installed in a closed or multicabinet assembly.
•
The additional weight of the switch does not exceed the cabinet's weight limits or
unbalance the cabinet in any way.
•
The cabinet is secured to ensure stability in case of unexpected movement, such as an
earthquake.
