Hard Disk Drive Lamp (DISK Lamp)
The disk lamp on the 3.5-inch disk bay has different meanings depending on the display status.
„ Lighting green
The hard disk is installed and powered on.
„ 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/RAID5 or RAID0+1), 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.
