3.4 Chassis Components
This section provides instructions on installing and replacing system components. To assure
compatibility, only use components that match the specifications or part numbers given.
Installation or replacement of most components require that power first be removed from the
system.
Storage Drives
The SC819U supports four 3.5" storage drives in toolless drive carriers that simplify their
removal from the chassis. These carriers also help promote proper airflow.
Your server may or may not have come with drives installed.
Drive Carrier Indicators
Each 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.
