Hard Disk Drive Lamp (DISK Lamp)

The disk lamp on the 3.5-inch disk bay has different meanings depending on the display status.

DISK lamps

„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.
