Note - Rear storage drives are supported only in the twelve 3.5-inch storage drive and twenty-four 2.5-inch storage drive configurations. Rear storage drives are not supported in the eight 2.5-inch storage drive configuration.
The system might have blank filler panels covering unoccupied drive slots.
If you removed an existing drive from a slot in the system, you must install the replacement drive in the same slot as the drive that was removed. Drives are physically addressed according to the slot in which they are installed. See Rear Panel Components and Cable Connections for boot drive locations.
