Reinstalling the controller module and setting time/date after RTC battery replacement

After you replace a component within the controller module, you must reinstall the controller module in the system chassis, reset the time and date on the controller, and then boot it.


  1. If you have not already done so, close the air duct or controller module cover.
  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.
    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 (QSFPs or SFPs), remember to reinstall them if you are using fiber optic cables.
  4. If the power supplies were unplugged, plug them back in and reinstall the power cable retainers.
  5. Insert the controller module into the chassis:
    1. Ensure the latching mechanism arms are locked in the fully extended position.
    2. Using both hands, align and gently slide the controller module into the latching mechanism arms until it stops.
    3. Place your index fingers through the finger holes from the inside of the latching mechanism.
    4. Press your thumbs down on the orange tabs on top of the latching mechanism and gently push the controller module over the stop.
    5. Release your thumbs from the top of the latching mechanisms and continue pushing until the latching mechanisms snap into place.
      The controller module begins to boot as soon as it is fully seated in the chassis. Be prepared to interrupt the boot process.
    6. Halt the controller at the LOADER prompt.
    The controller module should be fully inserted and flush with the edges of the chassis.
  6. Reset the time and date on the controller:
    1. Check the date and time on the healthy node with the show date command.
    2. At the LOADER prompt on the target node, check the time and date.
    3. If necessary, modify the date with the set date mm/dd/yyyy command.
    4. If necessary, set the time, in GMT, using the set time hh:mm:ss command.
    5. Confirm the date and time on the target node.
  7. At the LOADER prompt, enter bye to reinitialize the PCIe cards and other components and let the node reboot.
  8. Return the node to normal operation by giving back its storage: storage failover giveback -ofnode impaired_node_name
  9. If automatic giveback was disabled, reenable it: storage failover modify -node local -auto-giveback true
