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.
