Problem of RAID System

[?] Unable to rebuild the RAID array
 Is the capacity of the hard disk drive to be rebuilt correct?

Use a hard disk drive with the same capacity as that of the faulty hard disk drive.
 Is the logical drive RAID0?

RAID0 cannot be rebuilt because it has no redundancy. Replace the failed hard disk drive, reconfigure
the RAID array, and recover the drive using backup data.
[?] Unable to automatically rebuild the RAID array
 Did you wait for sufficient time until the hard disk drive was replaced?

Follow the steps below to use the auto-rebuilding feature.
(1) Remove a failure HDD.
(2) Wait for at least 90 seconds.
(3) Install a new HDD.
[?] The hard disk drive failed

Contact your sales representative.
[?] Additional battery is not found
 Are the cable between the battery pack and battery board and the control cable between the battery board
and battery connector connected correctly?

Connect the cables correctly.
 Is this message displayed after the battery is connected?

If the battery charging status is low, the battery is not found. If the battery is not found although 24 hours
has passed, restart the system once.
If the battery is not found although the above action has been taken, the additional battery may be faulty.
Contact your sales representative.
[?] DISK LED flashes
 Does DISK LED flashes frequently even while the hard disk drive is not accessed?

Ignore the flashing. When Patrol Read is running, the DISK LED flashes even if the hard disk drive is not
being accessed. If a SATA hard disk drive is used, the DISK LED stays on.
During the POST process, the controller is not visible or shows errors
[?]
