Brocade DCX 8510-4 Backbone QuickStart Guide
Publication Number: 53-1002178-01
Please note that the duplex clip on the mSFP end of the cable is black for easier recognition. See the appendix for a
listing of the qualified mSFP optical cables for the FC8-64 port blade.
If ISL Trunking is in use, group the cables by trunking group. The ports are color-coded to indicate which ports can be
used in the same ISL Trunking group: eight ports marked with solid black ovals alternate with eight ports marked
with oval outlines. See the appendix for a listing of supported cable speeds and distances.
Installing QSFP cables (optional)
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. Up to five
neighboring Brocade 8510 series chassis can be combined with the QSFP cables.
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.
The following table describes the connector port LED patterns and the recommended actions for those patterns.
Follow this procedure to install the QSFP cables. Refer to the
Fabric OS Administrator’s Guide
for the configuration
