• Two NVRAMS on the controller board are labeled 2M-1 and 2M-2.
  • These NVRAMs are a set. When replacing the controller board, remove both NVRAMs, 2M-1 and 2M-2, and then attach them to the new board at the same locations. If this is not done correctly, the machine will issue SC195-00.
  • When you position the NVRAMS over the sockets, make sure that the circular notch is pointing in the direction embossed on the board as shown below.
  • NVRAM 2M-1 is inserted into socket FRAM-1, and 2M-2 is inserted into the socket FRAM-2. Make sure that the circular notches on the NVRAMs point in the direction of arrows embossed on the board.

  • If the NVRAMs are installed incorrectly, this could cause both the board and the NVRAMs to short out and permanently damage the board and NVRAMs.
  • After the board is replaced, check which ESA applications have been installed, and then follow the installation procedures to re-install each application.
