3.3 Chassis Components
The following sections describe procedures for installing or replacing chassis components.
Storage Drives
The chassis supports sixteen 2.5" hot-swap hard drives. Only SAS or enterprise SATA HDDs
are recommended. The drives are mounted in drive carriers to simplify their installation and
removal from the chassis. These carriers also help promote proper airflow for the drive bays.
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.
