Installing a QSFP 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.
4. Once all the cables are attached, see the Fabric OS Administrator's Guide for the configuration procedure.

Possible QSFP cable configurations

The following figure illustrates one possible QSFP cable configuration between two 8510 series chassis. Up to six
neighboring 8510 chassis can be connected as long as each of two cores in one chassis is interconnected with each
of two cores in the next chassis. This provides for inter-chassis link (ICL) trunking between chassis, ensuring
redundancy. Parallel connections between core blades are recommended, but both parallel and mesh cable
arrangements are supported.
