Installing the controller module

After all of the components have been moved from the impaired controller module to the replacement controller module, you must install the replacement controller module into the chassis and then boot it to Maintenance mode.


  1. If you have not already done so, close the air duct:
    1. Swing the air duct all the way down to the controller module.
    2. Slide the air duct toward the risers until the locking tabs click into place.
    3. Inspect the air duct to make sure that it is properly seated and locked into place.

  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. Cable the management and console ports only, so that you can access the system to perform the tasks in the following sections.
    Note: You will connect the rest of the cables to the controller module later in this procedure.
  4. Plug the power cables into the power supplies and reinstall the power cable retainers.
  5. Complete the reinstallation of the controller module:
    1. Firmly push the controller module into the chassis until it meets the midplane and is fully seated.
      The locking latches rise when the controller module is fully seated.
      Attention: Do not use excessive force when sliding the controller module into the chassis to avoid damaging the connectors.

      The controller module begins to boot as soon as it is fully seated in the chassis. Be prepared to interrupt the boot process.

    2. Rotate the locking latches upward, tilting them so that they clear the locking pins, and then lower them into the locked position.
    3. If you have not already done so, reinstall the cable management device.
    4. Interrupt the normal boot process by pressing Ctrl-C.
