Reinstalling the controller

After you replace a component within the controller module, you must reinstall the controller module in the system chassis and boot it.


  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. Complete the reinstallation of the controller module:
    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.
      Attention: Do not use excessive force when sliding the controller module into the chassis; you might damage the connectors.
    2. Tighten the thumbscrew on the cam handle on back of the controller module.
    3. If you have not already done so, reinstall the cable management device.
    4. Bind the cables to the cable management device with the hook and loop strap.
    5. Reconnect the power cables to the power supplies and to the power sources, and then turn on the power to start the boot process.
  5. If your system is configured to support 10GbE cluster interconnect and data connections on 40GbE NICs or onboard ports, you must convert these ports to 10GbE connections with the nicadmin convert command from Maintenance mode.
    Note: Be sure to exit Maintenance mode after completing the conversion.
  6. Return the node to normal operation:
    If your system is in... Issue this command from the partner's console...
    An HA pair storage failover giveback -ofnode impaired_node_name
    A stand-alone configuration None required
  7. If automatic giveback was disabled, reenable it: storage failover modify -node local -auto-giveback true
