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

  1. Remove the controller box cover. (Controller Box Cover)
  2. Remove the controller bracket [A].
  3. Remove the controller board (PCB11) [A].
  4. Release the upper and lower locks and remove DIMM [A].

  5. Remove the used NVRAM [A] from the old controller board and install them on the new controller board.

    • Make sure that the NVRAM is placed at the right position and orientation when attaching to the new board.
    • Incorrect installation of the NVRAM will damage both the controller board and NVRAM.

  • When replacing the controller board (PCB11), first check if the SDK applications have been installed. After replacing the controller board, re-install the SDK applications by following the installation instructions for each application.
  • After reinstalling the SDK applications, print the SMC (SP-5-990-024/025 (SMC: SDK/Application Info)). Then open the proximity sensor cover. Store the SMC sheet and the SD card(s) that was used to install the SDK application(s).
