Cause : Pwr Brd Chksum1 comes when the checksum read from the EEPROM does not match the checksum that is calculated from the EEPROM data. The checksum read from the non-volatile storage does not match the checksum calculated. The data is set to the default value.
- Clear the fault or cycle power to the drive.
