Removing An Inter-Chassis Link (Qsfp) Cable; Installing An Icl Cable; Qsfp Cable And Transceiver (Bail Open) - IBM System Storage SAN384B-2 Installation, Service And User Manual

Removing an inter-chassis link (QSFP) cable

Complete the steps to remove a QSFP cable.
1. Remove the chassis door ("Removing and installing the chassis door" on page
67).
2. If you are replacing an ICL cable, note the cable routing, paying attention to
which cable end plug into which socket. Replace only one ICL cable at a time
to minimize errors.
3. Grasp the rubber housing on the end of the cable and pull it straight out of the
QSFP transceiver.
4. 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.

5. Repeat for each cable that requires replacement.
6. If you are not replacing the ICL cables, insert the rubber plugs into each QSFP
transceiver.

Installing an ICL cable

Complete the steps to install a QSFP cable.
1. Ensure that both cable and transceiver are clean prior to installation.
2. 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.
3. 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.
4. 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" on page 96 for one possible configuration between two chassis.
5. Replace the chassis door ("Removing and installing the chassis door" on page
67 ).
6. Once all the cables are attached, see the Fabric OS Administrator's Guide for the
configuration procedure.
