Replacing a QSFP transceiver
Complete the following steps to replace a QSFP transceiver.
1. 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.
2. 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.
3. Repeat for each cable that requires replacement.
Once all the cables are attached, refer to the Fabric OS Administrator's Guide for the configuration
procedure.

transceivers supported on the core blades.
Inter-chassis link (ICL) cable removal and replacement
Use this procedure to remove and replace ICL QSFP cables. Follow these guidelines while removing
and replacing ICL QSFP cables.
• 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 Brocade Backbones forming the ICL connection. Beginning with Fabric OS v7.0.1,
up to nine neighboring Brocade DCX 8510 series chassis can be connected with the QSFP cables.
Under Fabric OS v7.0.0, six chassis can be connected.
• For the Brocade DCX 8510 Backbones, an off-the-shelf QSFP cable up to 50 meters long can be
used as an ICL cable.
• For the Brocade DCX 8510 Backbones, if the QSFP cables are not used, make sure the rubber
gaskets are in the QSFP transceivers.
