Cabling a two-node switchless cluster

The optional data ports, optional NIC cards, and management ports on the controller modules are connected to switches. The cluster interconnect/HA ports are cabled on both controller modules.

Before you begin

You must have contacted your network administrator for information about connecting the system to the switches.

About this task

Be sure to check the illustration arrow for the proper cable connector pull-tab orientation.

Note: As you insert the connector, you should feel it click into place; if you do not feel it click, remove it, turn it around and try again.


  1. You can used the animation or the step-by step instructions to complete the cabling between the controllers and to the switches:
    Step Perform on each controller module
    Cable the cluster/HA ports to each other with the 100 GbE (QSFP28) cable:
    • e0a to e0a
    • e0d to e0d

    If you are using your onboard ports for a data network connection, connect the 100GbE or 40Gbe cables to the appropriate data network switches:
    • e0g and e0h

    If you are using your NIC cards for Ethernet or FC connections, connect the NIC card(s) to the appropriate switches:

    Cable the e0M ports to the management network switches with the RJ45 cables.

    DO NOT plug in the power cords at this point.
