• Keep NVRAMs away from any objects that can cause static electricity. Static electricity can damage NVRAM data.

  1. Remove the controller box. (Controller Box)

  2. Remove the slot cover [A].

  3. Remove the controller board (PCB3) [A] with the BiCU (PCB2) [B].

     

    • Be careful not to damage the backside of the controller board (PCB3) [A] and the BiCU (PCB2) [B].

  4. Remove the controller board (PCB3) [A] from the BiCU (PCB2) [B].
  5. Remove the two guide rails [A] from the controller board (PCB3) [B].
  6. Remove the NVRAM [A] from the old controller board (PCB3) and install them on the new controller board  (PCB3).

  • Make sure the NVRAM [A] is installed at the correct mounting location and orientation. Install the NVRAM so that the indentation on the NVRAM corresponds with the mark [B] on the controller board (PCB3).
  • Incorrect installation of the NVRAM will damage both the controller board (PCB3) and NVRAM.
