Connect the Cluster Cables

The cluster interface card provides three redundant links that enable two controllers to communicate with each other. The cluster I/O ports consist of two serial links (0,1) and an Ethernet link. Cluster cabling must be done before powering on either controller, and all three links must be established before configuration can proceed.

1. Locate the 3-port cluster interface card in PCIe slot 3.
2. Identify the three cluster cables provided for your engineered system.

   These are straight-through Cat-5-or-better Ethernet cables, and are typically 7 ft (2.15 m) in length.

3. Connect the cluster serial ports of each controller to form a crossover pattern:
   1. Connect one Ethernet cable between serial port 0 of one controller and serial port 1 of the other controller.
   2. Connect another Ethernet cable between serial port 1 of one controller and serial port 0 of the other controller.

      The cables between the serial ports form a crossover pattern.

4. Connect one Ethernet cable between the Ethernet ports of each controller.
