Follow these steps to add the optical transceivers and cables to the Fibre Channel
ports.
1. Ensure that both cable and transceiver are clean prior to installation.
2. Position one of the optical transceivers so that the key is oriented correctly to
the port. Insert the transceiver into the port until it is firmly seated and the
latching mechanism clicks.
Transceivers are keyed so that they can only be inserted with the correct
orientation. If a transceiver does not slide in easily, ensure that it is correctly
oriented.
3. Position a cable so that the key (the ridge on one side of the cable connector) is
aligned with the slot in the transceiver; then, insert the cable into the
transceiver until the latching mechanism clicks.
Cables are keyed so that they can only be inserted with the correct orientation.
If a cable does not slide in easily, ensure that it is correctly oriented.
4. Repeat steps 1 and 2 for the remaining ports.
5. Organize the cables as required. For recommendations regarding cable
management, refer to "Managing cables" on page 44.
6. Verify the chassis and port status using the switchShow command.
7. Verify fabric connectivity using the fabricShow command.
Follow these steps to install the QSFPs and cables in the 16 Gbps core blades.
These transceivers and cables are used to form the inter-chassis links (ICL) with
neighboring SAN384B-2 and SAN768B-2 backbones. The transceivers should be
installed in the blades before connecting the cables. Because each QSFP contains
four 16 Gbps ports, be aware that any problems with one port could affect all four
ports in the quad if the QSFP has to be replaced.
1. Position one of the QSFP transceivers so that the key is oriented correctly to the
port. Insert the transceiver into the port until it is firmly seated. Transceivers
are keyed so that they can only be inserted with the correct orientation. If a
transceiver does not slide in easily, ensure that it is correctly oriented. When
the transceiver is correctly seated, the status LED will flash amber several times
and then turn solid amber.
2. Remove the protective cap from the special QSFP cable and insert it into the
transceiver until it is firmly seated. The cables are also keyed to fit into the
transceivers correctly. When the cable is correctly seated, the status LED will
change from amber to green.
3. Repeat steps 1 and 2 for the remaining ICLs.
4. Organize the cables (see "Managing cables" on page 44).
5. Verify the chassis and connector and port status using the switchShow -qsfp
command. A sample of the command output is shown below. The example is
from a SAN384B-2 with a core blade installed in slot 3. Note that the state
reported for an unconnected QSFP (shown QSFP 0 and Ports 0-3 below) is
No_SigDet. This is different from the State of No_Synch that is reported for
regular SFPs that are unconnected. QSFP 7 (ports 3/28-3/31, Index 748-751) in
the example shows the results for a connected QSFP.
