Hard Disk Drive LEDs (Front Panel)

NSS2000 Getting Started Guide

26

The ACT and Error LEDs associated with each of the installed disk drives indicate 
disk-drive activity, or an error condition.

The various states of the ACT LED indicates the drive activity: 

•

Solid Green: The disk drive is configured but is currently idle.

•

Flickering Green: The disk drive is configured, active, and not rebuilding. 
Flickers off with activity.

•

Blinking Green: The disk drive is configured and a RAID array is currently 
rebuilding to the disk drive.

•

Off: The disk drive is not configured (not part of a RAID or JBOD array and 
not exported).

The various states of the Error LED indicate that the disk drive is in an error 
condition:

•

Solid Red: The disk drive is in a failed state.

•

Blinking Red: The disk drive is predicated to fail (via S.M.A.R.T.). We 
recommend that you replace the disk drive to avoid the loss of data.

•

Off: The drive is OK.

The USB LEDs on the front panel indicate the status of the USB flash drive:

•

Solid Green: The USB flash drive is connected and is not safe to remove.

•

Blinking Green: The USB flash drive is connected and is being mounted or 
unmounted.

•

Off: There is either no USB flash drive connected to the NSS, or, if 
connected, the USB hard/flash drive is safe to remove.
