Module type Signal Descriptions
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 and Type 10, these pins are not present
(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 an LED.
