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.
