Hard Disk Drive Lamp
The disk lamp on the hard disk drive bay has different meanings depending on the display status.
 Lit green
Indicates that power is supplied to the hard disk drive.
 Blinking green
Indicates that the hard disk drive is being accessed.
 Lighting amber
Indicates that 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.)
 Alternate lighting green or amber
Indicates that the hard disk drive is being rebuilt (this status is not a failure). If the defective hard disk drive is
replaced with a new one in the RAID System configuration, the data is automatically rebuilt (auto rebuild
function). During the rebuild operation, the LED blinks amber.
The LED goes off when the rebuild is terminated normally. The LED goes on amber if the rebuild fails.
IMPORTANT: 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.)
 Wait at least 90 seconds between the removal of a failed hard disk drive and the
installation of a new hard disk drive.
 Do not replace another hard disk drive while a rebuilding is already in progress.
