Removing an inter-chassis link (QSFP) cable
Complete these steps to remove a QSFP cable.
1.
Remove the chassis door (“Removing and installing the chassis door” on page
81).
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, see “Removing a QSFP
transceiver” on page 112.
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 these 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, follow the instructions in “Installing a
QSFP transceiver” on page 113.
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” for one possible
configuration between two chassis.
5.
Replace the chassis door (“Removing and installing the chassis door” on page
81).
6.
Once all the cables are attached, see the
Fabric OS Administrator’s Guide
for the
configuration procedure.
Possible ICL configurations
Figure 45 on page 116 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.
