Forced power on
To test and measure the voltages of power supplies of the PXIeCOMe, the chassis power supply should be turned on. This can be accomplished using PS_ON#.
This PS_ON# signal is however fully controlled by the COM Express module and so should be installed on the PXIeCOMe v0.4. So currently it is not possible to turn the power supply on when the PXIeCOMe is without a COM Express module. This could be changed in a future update of the PXIeCOMe, by adding a jumper connector between PE_PS_ON_N and GND (see PXIeCOMe schematic page Power Management On/Off/Standby and SMBus).
