D57 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.
This is a Type 2
