Installing Qsfp Cables (Optional) - Brocade Communications Systems PowerConnect B-DCX Quick Start Manual

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 six 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.

The figure below shows an QSFP cable and transceiver. The QSFP connectors on the core blades are labeled by
trunk group (trunking is optional) for ease of installation. The subsequent figures shows acceptable cabling
configurations for the ICL feature. The recommended topology is the parallel type where there are four QSFP cables
connected between any pair of Brocade 8510 series chassis.The full mesh configuration is also supported.
