Replacing the controller module hardware

To replace the controller module hardware, you must remove the degraded controller, 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. Opening the system
    To replace the controller module, you must first remove the old controller module from the chassis.
  2. Moving the NVMEM battery
    To move the NVMEM battery from the old controller module to the new controller module, you must perform a specific sequence of steps.
  3. Moving the boot media
    You must locate the boot media and follow the directions to remove it from the old controller module and insert it in the new controller module.
  4. Moving the DIMMs
    To move the DIMMs, you must follow the directions to locate and move them from the old controller module into the replacement controller module.
  5. Moving a caching module, if present
    If your system has a caching module, you need to move the caching module from the old controller module to the replacement controller module. The caching module is referred to as the M.2 PCIe card on the controller module label.
  6. 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.
