Environmental Considerations; Recommendations For Cable Management; Items Included With The Brocade 300 - Brocade Communications Systems 300 Hardware Installation Manual

Environmental considerations

For successful installation and operation of the switch, ensure that the following environmental requirements are met:
• At a minimum, adequate cooling requires that you install the switch with the non-port side, which contains the air intake vents,
facing the cool-air aisle.
• A minimum of 30.6 cubic meters/hour (18 cubic ft/min) and a maximum of 39.1 cubic meters/hour (23 cubic ft/min) of air
flow is available to the air intake vents on the non-port side of the switch.
CAUTION
Make sure the airflow around the front, and back of the device is not
restricted.
• Ensure that temperature requirements are met.
CAUTION
Do not install the device in an environment where the operating ambient temperature might exceed 40°C (104°F).

Recommendations for cable management

The minimum bend radius for a 50 micron cable is 5.08 cm (2 inches) under full tensile load and 3.05 cm (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:
NOTE
You should not use tie wraps with optical cables because they are easy to over tighten.
CAUTION
Before plugging a cable into any port, be sure to discharge the voltage stored on the cable by touching the electrical
contacts to ground surface.
• Plan for rack space required for cable management before installing the switch.
• 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 Brocade 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 hook and loop straps to secure and organize fiber optic cables.
