Installing the controller

After you install the components from the old controller module into the new controller module, you must install the new controller module into the system chassis and boot the operating system.

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.
Note
The system might update system firmware when it boots. Do not abort this process.
A video for this task is available at:
  1. If you are not already grounded, properly ground yourself.
  2. If you have not already done so, close the CPU air duct.
  3. If you have not already done so, make sure the NVMEM battery is plugged into the controller.
  4. 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.
  5. Cable the management and console ports so that you can access the system to perform the tasks in the following sections.
  6. Complete the reinstallation of the controller module:
    If your system is in...Then perform these steps...
    An HA pair

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

    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. Tighten the thumbscrew on the cam handle on back of the controller module.
      Attention
      Do not use excessive force when sliding the controller module into the chassis; you might damage the connectors.

      The controller begins to boot as soon as it is seated in the chassis.

    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. When you see Press Ctrl-C for Boot Menu, press Ctrl-C to interrupt the boot process.
    5. Select the option to boot to Maintenance mode from the displayed menu.
