Note: Each SFP has a 10-pad gold-plated PCB-edge connector on the bottom.
Insert SFPs into the upper row of ports with this gold edge down. Insert
SFPs into the lower row of ports with the gold edge up.
4. Connect the cables to the transceivers. The cables used in trunking groups must
meet specific requirements. For a list of these requirements, see the Fabric OS
Administrator's Guide.
Note: The cable connectors are keyed to ensure correct orientation. If a cable
does not install easily, ensure that it is correctly oriented.
a. Orient a cable connector so that the key (the ridge on one side of the
connector) aligns with the slot in the transceiver. Then, insert the cable into
the transceiver until the latching mechanism clicks. For instructions specific
to cable type, see the cable manufacturer's documentation.
b. Repeat step a for the remaining cables.
5. Check the LEDs to verify that all components are functional. For information
about LED patterns, see "Interpreting LEDs" on page 31.
6. Verify the correct operation of the switch by entering the switchShow
command from the workstation.
Managing cables
Attention: The minimum bend radius for a 50 micron cable is 2 in. under full
tensile load and 1.2 in. with no tensile load.
Cables can be organized and managed in a variety of ways, including using cable
channels on the sides of the cabinet or patch panels to minimize cable
management. Following is a list of 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 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 straps to secure and organize fibre optic cables. Do not use
tie wraps on fiber optic cables, because wraps are easily overtightened and can
damage the optical fibers.
Verifying the correct operation of the switch and backing up
the configuration
To verify the correct operation of the switch and to back up the switch
configuration, complete these steps:
1. Check the LEDs to verify that all components are functional. For information
about LED patterns, refer to "Interpreting LEDs" on page 31.
2. If necessary, log on to the switch by Telnet, using the admin account.
3. Run the portCfgPersistntEnable command to activate the FC ports for FC
operation.
