4. Disconnect the fiber optic cables that connect the ASIC board to the
three Gate Driver boards at the Gate Driver board ends.
5. Disconnect the plug from the X6 connector on the ASIC board.
6. Make the following connections from a High Voltage DC Test Power
Supply to X6 on the ASIC board using a new connector plug.
