L860 module uses PCIe interface. According to the PCIe specification, the PCIe Vmain should be used as
the +3.3V power source, not the Vaux. The Vaux is the PCIe backup power source and it is not sufficient
as the power supply. In addition, the DC/DC power supply other than PCIe ports should not be used as
the external power cannot control the module status through the PCIe protocol.
