4. Repeat for each cable and transceiver that you are replacing.
Installing a QSFP transceiver
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 QSFP that you are installing.
5.
Once all the cables are attached, see the Fabric OS Administrator’s Guide for the
configuration procedure.
6. Replace the chassis door (“Removing and installing the chassis door” on page
81).
Removing and replacing inter-chassis link (QSFP) cables
Use this procedure to remove and install ICL QSFP cables. Follow these guidelines
while removing and replacing ICL QSFP cables.
v
The QSFP ports on the core switch blades can be used only with an inter-chassis
link (ICL) license. After the addition or removal of a license, the license
enforcement is performed on the ports only when the
portDisable
and
portEnable
commands are issued on the ports. An ICL license must be installed
on all systems forming the ICL connection. Beginning with Fabric OS v7.0.1, up
to nine neighboring SAN384B-2 and SAN768B-2 chassis can be connected with
the QSFP cables. With Fabric OS v7.0.0, a maximum of six chassis can be
connected.
v An off-the-shelf QSFP cable up to 50 meters long can be used as an ICL cable.
v
If QSFP cables are not in use, make sure the rubber gaskets are in the QSFP
transceivers.
Table 16 on page 114 describes the ICL connector port LED patterns and the
recommended actions for those patterns.
