Environmental considerations
For successful installation and operation of the switch, ensure that the following environmental
requirements are met:
IMPORTANT: Always use the plenum when installing the switch in a rack.
• At a minimum, adequate cooling requires installing the switch with the intake side, the nonport
side of the switch, facing the cool-air aisle.
NOTE: For switches with Port Side Air Intake, install the switch with the port side facing the
cool-air aisle.
• 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 airflow must be available for air intake.
• The ambient air temperature must not exceed 40°C (104°F) while the switch is operating.
Cabling considerations
You can organize and manage cables in a number of ways, such as using cable channels on the
sides of the cabinet or patch panels.
Before installing the switch, consider the following HP cabling recommendations:
• HP recommends using HP PremierFlex cables because they have a minimum bend radius of
2 mm (0.08 inch) compared to previous cables, which required a minimum 5 cm (2 inches)
bend radius for a 50-micron cable under full tensile load and 3 cm (1.2 inches) with no tensile
load.
• Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and
replace the switch, allows for inadvertent movement of the rack, and helps prevent the cables
from being bent to less than the minimum bend radius.
• If you are using ISL Trunking, consider grouping cables by trunking groups. The cables used
in trunking groups must meet specific requirements, as described in the Fabric OS
Administrator's Guide.
• For easier maintenance, label the fiber optic cables and record the devices to which they are
connected.
• Keep LEDs visible by routing port cables and other cables away from the LEDs.
• Use Velcro straps to secure and organize fiber optic cables.
CAUTION: Do not use tie wraps on fiber optic cables. The wraps are easily overtightened
and can damage the optical fibers.
