DANGER
Use only optical transceivers that are qualified by Brocade Communications Systems
LLC. 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, Brocade strongly recommends cleaning 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, Brocade recommends using 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 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.
v
Plan for rack space required for cable management before installing the switch.
v
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.
v
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.
v
For easier maintenance, label the fiber-optic cables and record the devices to which they are connected.
v
Keep LEDs visible by routing port cables and other cables away from the LEDs.
v
Use hook and loop style straps to secure and organize fiber-optic cables.
Installing an SFP+ transceiver
About this task
The device supports only IBM-qualified transceivers. If you use an unqualified transceiver, the
switchshow
command output shows the port in a Mod_Inv state. Fabric OS also logs the issue in the
system error log. To insert an SFP+ transceiver, complete the following steps:
