Technical data

a) Remove the plug from the port to be used.
b) Position a transceiver so that it is oriented correctly and insert it into a port until it is firmly
seated and the latching mechanism clicks.
For instructions specific to the type of transceiver, refer to the transceiver manufacturer’s
documentation.
NOTE
The transceivers are keyed to ensure correct orientation. If a transceiver does not install
easily, ensure that it is correctly oriented.
c) Repeat steps a and b for the remaining ports, as required.
2. Connect the cables to the transceivers.
The cables used in trunking groups must meet specific requirements. For a list of these
requirements, refer to the Fabric OS Administrator's Guide.
NOTE
A 50-micron cable should not be bent to a radius less than 2 in. under full tensile load and 1.2 in.
with no tensile load. Tie wraps are not recommended for optical cables because they are easily
overtightened.
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, refer to the cable manufacturer’s
documentation.
NOTE
The cable connectors are keyed to ensure correct orientation. If a cable does not install
easily, ensure that it is correctly oriented.
b) Repeat step a for the remaining cables as required.
Verifying correct operation and backing up the configuration
Perform the following steps to verify correct operation and back up the switch configuration.
1. Check the LEDs to verify that all components are functional. For information about LED patterns,
refer to LED activity on page 31.
2. Enter the portcfgpersistentenable command to activate the FC ports for FC operation.
3. Verify the correct operation of the switch by entering the switchShow command from the
workstation.
This command provides information about switch and port status.
