Chassis SC822 User's Manual 3.3 Chassis Components Several components are accessable in the chassis. The following sections describe the method for each. Storage Drives for SC822T Chassis The SC822T chassis supports six 3.5" storage drives in drive carriers to simplify their removal from the chassis. These carriers also help promote proper airflow. Drive Carrier Indicators (SC822T model only) Each drive carrier has two LED indicators: an activity indicator and a status indicator. In RAID configurations, the status indicator provides information. In non-RAID configurations, the status indicator remains off. See the table below for details. 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 http://www. supermicro.com/products/nfo/files/storage/SBB-HDDCompList.pdf.
