Brocade Communications Systems DCX 8510-4 manual Qsfp cable insertion

Inter-chassis link (QSFP) cable removal and replacement 5

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.

Table 10 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 procedure and requirements.

Figure 31 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.
