Description
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.
Description
Primary power input: +12V nominal (wide range 5 ~ 20V).
All available VCC_12V pins on the connector(s) shall be used
Ground - DC power and signal and AC signal return path.
All available GND connector pins shall be used and tied to carrier
board GND plane.
