The TYPE pins indicate to the Carrier Board the Pin-out Type that is
implemented on the module. The pins are tied on the module to
either ground (GND) or are no-connects (NC). For Pin-out Type 1,
these pins are don't care (X).

The Carrier Board should implement combinatorial logic that monitors
the module TYPE pins and keeps power off (e.g. deactivates the
ATX_ON signal for an ATX power supply) if an incompatible module
pin- out type is detected. The Carrier Board logic may also implement
a fault indicator such as a LED.

NC Pin-out R2.0
PD Pin-out Type 10 pull down to ground with 4.7K resistor
12V Pin-out R1.0
This pin is reclaimed from the VCC_12V pool. In R1.0 Modules this
pin will connect to other VCC_12V pins. In R2.0 this pin is defined as
a no connect for types 1-6. A Carrier can detect a R1.0 Module by
the presence of 12V on this pin. R2.0 Module types 1-6 will no
connect this pin. Type 10 Modules shall pull this pin to ground
through a 47K resistor.
