3.2 3.5" Drive Hot-Swap Backplane Overview

Systems with 12-drive configurations have their own unique backplane. The backplanes mount to the back
of the drive bay assembly.
There are 12 hard disk drive interface connectors mounted on the front side of each backplane, each
providing both power and I/O signals to the attached hard disk drives.
