Hard Drive Carrier Indicators
Each hard drive carrier has two LED indicators: an activity indicator and a status indicator. In
RAID configurations, the status indicator lights to indicate the status of the drive. In non-RAID
configurations, the status indicator remains off. See the table below for details.
