Inter-chassis link (QSFP) cable removal and replacement

Inter-chassis link (QSFP) cable removal and replacement

Use this procedure to remove and replace a QSFP cable.
NOTE
The QSFP ports 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 Brocade
Backbones forming the ICL connection. Beginning with Fabric OS v7.0.1, up to nine neighboring
Brocade 8510 series chassis can be connected with the QSFP cables. Under Fabric OS v7.0.0, six
chassis can be connected.
NOTE
For the Brocade 8510 Backbones, an off-the-shelf QSFP cable up to 50 meters long can be used as
an ICL cable.
ATTENTION
For the 8510 series models, if the QSFP cables are not used, make sure the rubber gaskets are in
the QSFP transceivers.
