Reinstalling the controller module and booting the system

After you replace a FRU in the controller module, you must reinstall the controller module and reboot it.

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. 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 system, as needed.
    If you removed the media converters (SFPs), remember to reinstall them if you are using fiber optic cables.
  4. Plug the power cord into the power supply, reinstall the power cable locking collar, and then connect the power supply to the power source.
  5. Complete the reinstallation of the controller module:
    1. If you have not already done so, reinstall the cable management device.
    2. 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.

    3. Rotate the locking latches upward, tilting them so that they clear the locking pins, and then lower them into the locked position.
    4. Interrupt the boot process by pressing Ctrl-C when you see Press Ctrl-C for Boot Menu.
    5. Select the option to boot to Maintenance mode from the displayed menu.
