Cause : HiHp Bus CRC Er comes when Bus Communication CRC Error - too many Cycling Ring Checksum (CRC) errors have occurred in the communication bus.
- A fast power cycle may cause the 700S Main Control Board to attempt to communicate with the ASIC Board before the ASIC Board is energized.
- Check fiber-optic connections between the Power Interface Circuit Board and Voltage Feedback Circuit Board.
- Wait five minutes before re-energizing the drive
