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 power is supplied to the hard disk drive.
Blinking 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 RAID system, the data is
automatically rebuilt (auto rebuild function). During the rebuild process, the lamp is lit
green or amber alternately.
The lamp goes off when the rebuild is completed normally. The lamp goes on amber if the
rebuild fails.
IMPORTANT:
case, restart the server, hot-swap the failed hard disk drive, and restart
rebuilding. Observe the following notes to use the auto-rebuild feature.
Do not power off the server. (If the server is powered off before
rebuilding hard disk drives, the auto-rebuild feature will not start.)
When you removed a hard disk drive, wait at least 90 seconds
before installing the hard disk drive back again.
Do not replace another hard disk drive while rebuilding is in
progress.
