Chapter 5: Chassis Setup and Maintenance
5-3 Installing and Removing Hard Drives
The SC827 chassis contains four individual motherboards in separate node draw- ers. Each motherboard node controls a set of three hard drives. Note that if a motherboard node drawer is pulled out of the chassis, the hard drives associated with that node will power down as well.
