Replacing the CPU or power supply board
You may have to replace a circuit board if there is damage to one of its
components. Before replacing a circuit board, check the troubleshooting
flowcharts or call VEGA Field Service to be sure a replacement is
necessary.
The sensor EEPROM contains a backup of the CPU board EEPROM. After
replacing the CPU board, you must perform a memory backup to update the
CPU board’s EEPROM with the information in the sensor board EEPROM.
