3.4 Chassis Components

Hard Drives

The SC946L JBOD chassis supports forty five 3.5" hard drives. They can be removed without
powering down the system if your operating system supports RAID. In addition, it supports
two 2.5" drives accessible at the rear of the chassis.

Hard Drive Carrier Indicators

Each hard drive carrier has two LED indicators: an activity indicator and a status indicator.
The status indicator functions in RAID configurations. For non-RAID configurations, it remains
off. See the table below for details.
