Storage Drives; Drive Carrier Indicators - Supermicro SuperServer 420GH-TNGR User Manual

3.7 Storage Drives

A total of four NVMe/SATA/SAS hybrid drives may be housed in the CSE-428G2 chassis. All
four drive bays are hybrid.
The drives are mounted in drive carriers to simplify their installation and removal from the
chassis. (Both procedures may be done without removing power from the system.) These
carriers also help promote proper airflow.
Note: Enterprise level hard disk drives are recommended for use in Supermicro chassis and
servers. For information on recommended HDDs, visit the Supermicro website at
supermicro.com/products/nfo/storage.cfm

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.
