Indicates the statuses of the hard disks.

When using the RAID 5 function (*1), these indicators
will display the statuses as follows when an error
occurs.
Lights red:
Indicates that the respective hard disk is
the first drive that had an error.
Blinks red:
Indicates that the respective hard disk is
the second drive that had an error.
Lights red and orange alternately:
Indicates that the
respective hard disk is currently being recovered in
the RAID 5 mode (*1).

optional RAID card is installed and configured.

Basically, each indicator will indicate the status of

same status when a system error occurs.
Important:
When the indicator lights red, replace the
respective hard disk immediately.
If 2 HDD access indicators or more light/blink red, it
may be impossible to recover data on the respec-
tive hard disks.
