Hard Disk Drive Lamp

The disk lamp on the hard disk drive bay has different meanings depending on the display status.
3.5-inch hard disk drive
Lighting green

Indicates that the hard disk drive is accessed.
Lighting amber

Indicates that the installed hard disk drive is defected in the RAID System.
NOTE:
(RAID1, RAID5, RAID6, or RAID10), a single failed hard disk drive
(two hard disk drives in RAID6) does not affect the operation of the
server. However, it is recommended to replace the failed hard disk drive
and rebuild (reconfigure) the hard disk drives as soon as possible. (You
can hot-swap such a failed hard disk drive.)
Alternate lighting green or amber

Indicates that the hard disk drive is being rebuilt (this status is not a failure). If the
defected hard disk drive is replaced with a new one in the RAID System configuration, the
data is automatically rebuilt (auto rebuild function).
The lamp goes on green when the rebuild is terminated normally. The lamp goes on amber
if the rebuild fails.
IMPORTANT: Observe the following notes to use the auto-rebuild
feature.
Do not power off or reset the server.

When you removed a hard disk drive, wait at least 90 seconds

before installing the hard disk drive again.
Do not replace another hard disk drive while rebuilding is in

progress.
