IBM SAN384B-2, Installation, Service And User Manual

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.
Removing and replacing inter-chassis link (QSFP) cables
Use this procedure to remove and install QSFP cables.
Note: ICL ports can be used only with an ICL license. After the addition or
removal of a license, the license enforcement is performed on the ICL 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. An
off-the-shelf QSFP cable up to 50 meters long can be used as an ICL cable.
Attention: If QSFP cables are not in use, make sure the rubber gaskets are in the
QSFP transceivers.
Table 15 describes the ICL connector port LED patterns and the recommended
actions for those patterns.
