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:
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 ICL 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 Do not route the cables in front of air vents.
v Use Velcro
®
type straps to secure and organize fiber-optic cables.
v Route the cables away from LEDs to keep them visible.
v 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.
Note: Do not use tie wraps with optical cables because they are easily
overtightened and can damage the optic fibers.
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:
Note: Always use the pull tab to insert or remove 16 Gbps and 32 Gbps
transceivers as they might be hot.
Procedure
1. Perform one of the following steps, depending on your transceiver type.
v If transceiver has a pull tab (16- and 32-Gbps SFP+ transceivers), use the pull
tab to help push the transceiver into the port until it is firmly seated and the
latching mechanism clicks.
