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 Pinout 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 an LED.
