Red Flashing
In the event that a drive fails, the Red indicator turns on and an alarm sounds. You can turn off
the alarm by unlocking the drive carrier.
The drive carrier lock acts as an On/Off switch for the drives and
provides security by preventing non-key holders from accessing the
drives.
To lock each carrier, insert the key and turn it in a clockwise
direction. To unlock a carrier, turn the key in a counterclockwise
direction.
Disk Status/ Rebuild Indicators
The upper indicator represents the top drive carrier, the lower indicator represents the bottom
drive carrier. If a drive fails, the appropriate indicator turns on and an audible alarm sounds.
You can turn off the audible alarm by unlocking the drive carrier.
The red indicator of the target disk will light up and blink while rebuilding.
Rebuilding Activity/ Error Message Indicator
Rebuilding Activity:
This row of eight indicators shows disks rebuilding activity. In normal operation, a green light
scans across the bank of indicators. If you are using the online recovery feature to rebuild a
drive, all the indicators will turn on at the same time. The left-side indicator blinks and then
turns off when 12.5% of the data has been mirrored. Then the next indicator blinks and turns
off when 25% of the data has been mirrored, and so on.
Error Message
The chart offers the all-possible error messages, and can help you to identify certain
problems.
