1. If the QSFP transceiver is being replaced, grasp the bail of the new QSFP and
push the QSFP into the connector on the blade until it is firmly seated. The
QSFP is keyed to fit into the connector in one way. The status LED initially
blinks amber after installation, then displays steady amber.
2. Grasp the QSFP cable by the rubber housing and push it into the QSFP
transceiver until it is firmly seated. The cable housing is keyed to fit into the
QSFP in one way.
The status LED displays steady amber until both ends of the cable are inserted
and the link is established. When the link is fully established, the LED displays
steady green.
3.
Repeat for each cable that you are installing.
If you are installing ICL cables for the first time, pay particular attention to the
configuration in which the cables must be installed. See “Possible ICL
configurations” for one possible configuration between two chassis.
4. Replace the chassis door (“Removing and installing the chassis door” on page
67 ).
5. Once all the cables are attached, see the Fabric OS Administrator’s Guide for the
configuration procedure.
Possible ICL configurations
Figure 47 on page 96 illustrates one possible QSFP cable configuration between two
SAN384B-2 or SAN768B-2 chassis. Each of two cores in one chassis should be
interconnected with each of two cores in the second chassis. This provides for
inter-chassis link (ICL) trunking between chassis, ensuring redundancy. Parallel
connections between core blades are recommended.
