1. Grasp the rubber housing on the end of the cable and pull it straight out of the QSFP transceiver.
2. If the QSFP transceiver also needs to be replaced, remove the QSFP transceiver by rotating the
bail down and using the bail to pull the transceiver out of the connector on the blade.
3. Repeat for each cable that requires replacement.

Replacing an ICL cable
Complete the following steps to replace a QSFP cable.
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.
Once all the cables are attached, refer to the Fabric OS Administrator's Guide for the configuration
procedure.
Possible ICL configurations
The following figure illustrates one possible QSFP cable configuration between two DCX 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.
