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
Do not use the port cover tabs to lift the module. They are not designed to support the weight of the module,
which can fall and be damaged.
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.
Cable Management
The minimum radius that a 50-micron cable can be bent under full tensile load is 5.1 cm (2 in.). For a cable under no
tensile load, that minimum is 3.0 cm (1.2 in.). 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
additional recommendations:
•
Plan for the required rack space 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 ICL 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 are connected.
•
Keep LEDs visible by routing port cables and other cables away from the LEDs.
•
Do not route the cables in front of air vents.
•
Use Velcro-type straps to secure and organize fiber-optic cables.
•
Route the cables away from LEDs to keep them visible.
•
The cable management comb attaches to the lower part of the chassis and allows for simple cable management. The
comb can be installed without service disruption.
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.
