Environmental considerations
For successful installation and operation of the switch, ensure that the following environmental requirements are
met:
•
Because the Brocade VDX 6720 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
°
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.
•
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 maintains
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 multi-cabinet 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.
