Installing Transceivers and Cables
The device supports only transceivers that are qualified for Brocade products.
For current information on qualified transceivers supported by this device, refer to the
Brocade Transceiver Support Matrix
and the Brocade Transceiver Modules webpage on www.broadcom.com.
Precautions Specific to Transceivers and Cables
DANGER
All fiber-optic interfaces use Class 1 lasers.
DANGER
Use only optical transceivers that are qualified by Broadcom and that comply with the FDA Class 1 radiation
performance requirements defined in 21 CFR Subchapter I and with IEC 60825 and EN60825. Optical products
that do not comply with these standards might emit light that is hazardous to the eyes.
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.
Cleaning the Fiber-Optic Connectors
To avoid problems with the connection between the fiber-optic transceiver and the fiber cable connectors, clean both
connectors each time you disconnect and reconnect them . Dust can accumulate on the connectors and cause problems
such as reducing the optic launch power.
To clean the fiber cable connectors, use a fiber-optic reel-type cleaner. When not using a connector, make sure to keep
the protective covering in place.
Managing Cables
The minimum bend radius for a 50-micron cable is 2 in. under a full tensile load and 1.2 in. with no tensile load. Cables
can be organized and managed in various ways, for example, using cable channels on the sides of the rack or patch
panels to minimize cable management. Follow these recommendations:
NOTE
Do not use tie wraps with optical cables because they are easily overtightened and can damage the optic fibers.
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 the rack space required for cable management before installing the switch.
•
Leave at least 1m (3.28 ft) of slack for each port cable. This slack 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 that are used in
trunking groups must meet specific requirements, as described in the
Brocade Fabric OS Administration 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 style straps to secure and organize fiber-optic cables.
