Installing Transceivers and Cables
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 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 (SFP+ or QSFP) 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 an SFP+ or QSFP connector,
make sure to keep the protective covering in place.
Managing Cables
The minimum bend radius for a 50-micron cable is 2 inches under a 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. Follow these recommendations:
NOTE
You should 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 proper 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 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 connect.
•
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.
Installing an SFP+ Transceiver
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
