Installing the controller module

After you install the controller module and any other components into the new chassis, you need to boot it to a state where you can run the interconnect diagnostic test.

About this task

For HA pairs with two controller modules in the same chassis, the sequence in which you install the controller module is especially important because it attempts to reboot as soon as you completely seat it in the chassis.

Steps

  1. Align the end of the controller module with the opening in the chassis, and then gently push the controller module halfway into the system.
    Note: Do not completely insert the controller module in the chassis until instructed to do so.
  2. Recable the console to the controller module, and then reconnect the management port.
  3. Repeat the preceding steps if there is a second controller to install in the new chassis.
  4. Complete the installation of the controller module
    1. With the cam handle in the open position, firmly push the controller module in until it meets the midplane and is fully seated, and then close the cam handle to the locked position.
      Attention: Do not use excessive force when sliding the controller module into the chassis to avoid damaging the connectors.
    2. If you have not already done so, reinstall the cable management device.
    3. Bind the cables to the cable management device with the hook and loop strap.
    4. Repeat the preceding steps for the second controller module in the new chassis.
  5. Connect the power supplies to different power sources, and then turn them on.
  6. Boot each node to Maintenance mode:
    1. As each node starts the booting, press Ctrl-C to interrupt the boot process when you see the message Press Ctrl-C for Boot Menu.
      Note: If you miss the prompt and the controller modules boot to ONTAP, enter halt, and then at the LOADER prompt enter boot_ontap, press Ctrl-C when prompted, and then repeat this step.
    2. From the boot menu, select the option for Maintenance mode.
