Up to 12 DNR I/O boards can be installed in the chassis; DNR I/O boards are
functionally identical to the corresponding DNA boards for the PowerDNA Cube.
The only differences between RACK and Cube I/O boards are the mounting
hardware. The DNA version I/O boards are designed to stack in a Cube chassis.
The DNR version I/O boards are designed to plug into the backplane of a RACK
chassis.
