nonport side of the switch. The temperature inside the switch can be up to 80 ºC (176
ºF) during switch operation. If the internal temperature range exceeds the operating
ranges of the components, the LEDs, error messages, and Fabric W atch alerts indicate
a problem. Enter the tempshow or Fabric Watch command to view temperature
status.
NOTE:
For a complete list of environmental considerations, see Table 25 on page 136.
Rack specifications
If you are installing the switch in a rack:
• Plan a rack space tha t is one rack unit (4.45 cm or 1.75 in) high, 48.3 cm (19
in) wide, and at least 76.2 cm (30 in) deep.
• Verify that the rack is mechanically secured to ensu re stability in the event of an
earthquake or other natural disaster.
• Ground all equipment in the rack through a reliable branch circuit connection;

branch circuit, such as a power strip.
• Ensure that airflow and temperature requirements are met on a n ongoing basis,
especially if the switch is installed in a closed or multi-rack assembly.
• Verify that the additional weight of the switch does not exceed the rack’s weight
limits or unbalance the rack in any way.

The air is expelled through vents in the front (port side) of the chassis. HP
recomme
nds installing the switch so that air intake and exhaust for all components in
the rack
are flowing in the same front-to-back direction.
Follow
these guidelines to ensure proper airflow and to prevent component overheating:
• Install the switch with the nonport side (which contains the air intake vents) facing
the cool-air aisle.
• Ensure
that all equipment in the rack forces air in the same direction to avoid
taking in exhaust air.
• Ensure that a minimum of 24 cu ft/min of airflow is available to the air intake
vents
on the nonport side of the switch.
