Description
PCI Express Graphics lane reversal input strap.
Pull low on the Carrier board to reverse lane order.
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 (5 ~ 20V wide input).
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.
