Hard Disk Drive Lamp
The disk lamp on the 3.5-inch hard disk drive bay has different meanings depending on the display
status.
 Lighting green
Indicates that the power is supplied to the hard disk.
 Blinking green
Indicates that the hard disk is accessed.
 Lighting amber
Indicates that the installed hard disk is defected in the disk array configuration.
NOTE: While hard disks are in the disk array configuration (RAID1 or
RAID5), a single failed hard disk does not affect the operation of the
server. However, it is recommended to replace the failed hard disk
and auto-rebuild (reconfigure) the hard disks as soon as possible.
(You can hot-swap such a failed hard disk.)
 Alternate lighting green or amber
Indicates that the hard disk is being rebuilt (this status is not a failure). If the defected
hard disk is replaced with a new one in the disk array configuration, the data is
automatically rebuilt (auto rebuild function). During the rebuild operation, the lamp is lit
green or amber alternatively.
The lamp goes off when the rebuild is terminated normally. The lamp goes on amber if
the rebuild fails.
IMPORTANT: To abort rebuilding, power off the server. In such a
case, restart the server, hot-swap the failed hard disk, 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 disks, the auto-rebuild feature will not start.)
 When you removed a hard disk, wait at least 90 seconds before
installing the hard disk back again.
 Do not replace another hard disk while rebuilding is in progress.
