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.
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.
NOTE
Do not use tie wraps with optical cables because they are easily overtightened and can damage the optic fibers.
Installing an SFP+ Transceiver
NOTE
For current information on qualified transceivers supported by this device, refer to the Brocade Fibre Channel
Transceiver Support Matrix and Brocade Transceiver Modules on www.broadcom.com.
The device supports only Brocade-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:
NOTE
Always use the pull tab to insert or remove 16Gb/s and 32Gb/s transceivers since they might be hot.
1. Perform one of the following steps, depending on your transceiver type.
•
If the transceiver has a pull tab (16Gb/s and 32Gb/s SFP+ transceivers), use the pull tab to help push the
transceiver into the port until it is firmly seated and the latching mechanism clicks.
