Installing the controller

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


  1. If you are not already grounded, properly ground yourself.
  2. 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.
  3. Recable the console to the controller module, and then reconnect the management port.
  4. Connect the power supplies to different power sources, and then turn them on.
  5. With the cam handle in the open position, slide the controller module into the chassis and firmly push the controller module in until it meets the midplane and is fully seated, and then close the cam handle until it clicks into the locked position.
    Attention: Do not use excessive force when sliding the controller module into the chassis; you might damage the connectors.
    The controller module begins to boot as soon as it is fully seated in the chassis.
  6. Repeat the preceding steps to install the second controller into the new chassis.
  7. 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.
