4. DISK ACCESS lamp
Lights green : the hard disk drives is being accessed.
5. POWER/SLEEP lamp
Lights green : the server is powered.

If the OS supports a power-saving mode, the green lamp flashes while the
server is in this power-saving mode. Pressing the POWER switch places the
server back in the normal mode.
6. DISK lamps
Each hard disk drive has a DISK lamp on its front panel. (1) in below figure
Figure 5: Disk lamp
Lights green : power is supplied to the hard disk drive.
Blinks green : the hard disk drive is being accessed.
Lights amber : the hard disk drive is defective in the RAID System
configuration.
Note:
While hard disk drives are in a RAID System configuration (RAID1/
RAID5, RAID6, RAID10, or RAID50), a single failed hard disk drive does
not affect the operation of the server.
However, we recommend you replace the failed hard disk drive and auto-
rebuild (reconfigure) the hard disk drives as soon as possible. (You can hot-
swap such a failed hard disk drive.)
Blinks amber : during the data rebuild operation; when the defective hard disk
drive is replaced with a new one in the RAID System configuration.
Blinks green/amber : the hard disk drive is being rebuilt (this status is not a
failure).
Off : when the rebuild is terminated normally. The LED goes on amber if the
rebuild fails.
Caution:
To abort a rebuild, power off the server. In such a 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.
