Inter-chassis link (QSFP) cable removal and replacement 5
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 requires replacement.
4. Once all the cables are attached, see the Fabric OS Administrator’s Guide for the configuration
procedure.
Possible ICL configurations
Figure 33 illustrates one possible QSFP cable configuration between two 8510 series 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.
