Replacing the controller module hardware

To replace the controller module hardware, you must remove the impaired node, move FRU components to the replacement controller module, install the replacement controller module in the chassis, and then boot the system to Maintenance mode.
  1. Removing the controller module
    You must remove the controller module from the chassis when you replace a component inside the controller module.
  2. Moving the power supplies
    You must move the power supplies from the impaired controller module to the replacement controller module when you replace a controller module.
  3. Moving the fans
    You must move the fans from the impaired controller module to the replacement module when replacing a failed controller module.
  4. Moving the boot media
    There is one boot media device in the DG5000 under the air duct in the controller module. You must move it from the impaired controller module to the replacement controller module.
  5. Moving the DIMMs
    To move the DIMMs, locate and move them from the impaired controller into the replacement controller and follow the specific sequence of steps.
  6. Moving a mezzanine card
    To move a mezzanine card, which is also referred to as a host interface card (HIC), you must remove the cabling and any QSFPs and SFPs from the ports, move the mezzanine card to the replacement controller, reinstall any QSFPs and SFPs onto the ports, and cable the ports.
  7. Moving the NV battery
    When replacing the controller module, you must move the NV battery from the impaired controller module to the replacement controller module
  8. 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.
