When Installing the New Controller Board

1. Remove the NVRAMs from the old controller board.
2. Install them on the new controller board after you replace the controller board.
3. Replace the NVRAMs if the NVRAM on the old controller board is defective.

Make sure you print out the SMC reports ("SP Mode Data" and "Logging Data")
before you replace the NVRAMs.

Keep NVRAMs away from any objects that can cause static electricity. Static
electricity can damage NVRAM data.

Make sure the NVRAMs are correctly installed on the controller board.

Make sure that the DIP-switch settings on the old controller board are the same for
the new controller board. Do not change the DIP switches on the controller board
in the field.
