Installation and safety considerations

DRAFT: BROCADE CONFIDENTIAL
•
The ambient air temperature does not exceed 40
°
C (104
°
F) while the switch is operating.
Table 2 lists the acceptable environmental ranges for both operating and nonoperating (such as
during transportation or storage) conditions.
Rack considerations
For successful installation and operation of the switch in a rack, ensure the following rack
requirements are met:
•
The rack must be a standard EIA rack.
•
A rack space that is two rack units (2U) high; 8.90 cm (3.50 inches) high and 48.3 cm (19
inches) wide.
•
The equipment in the rack 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 multirack assembly.
•
The additional weight of the switch does not exceed the rack’s weight limits or unbalance
the rack in any way.
•
The rack is secured 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.
Cables can be organized and managed in a variety of ways, for example, using cable channels on
the sides of the rack or patch panels to minimize cable management. Following is a list of
recommendations:
