The power supply does have a 5 pin PS AUX cable. Is Intel calling the PS AUX what others are referring to as the PMBus? If so, I should be able to make the connection between the PMBus specification and the BMI Sensor Tables in the Intel TPS to what information from the PMBus is being used by the BMI to determine the Power Unit Redundancy Status.
The Intel TPS does refer to PMBus being required but only for determine power consumption and use in Intel Node Manager. The current consumption entries in Intel Active System console show " no sensor found" . Based on that information, it appears that the PS Aux cable from the power supply isn't compatible with the motherboard or I am missing a setup step to make the motherboard monitor the PMBus. If it isn't compatible, it appears I currently have no way to determine where the issue is or who is at fault if the PMBus v1.2 specification is what determined the communication over the PS Aux cable.
Does anyone know of a certain procedure that is required for the BMI to use the PS Aux connection?
I am only aware of a re-flash of the firmware to make it re-scan sensors.
Is anyone aware of any utilities to view what is coming in the PS Aux interface from the EFI Shell or Windows (Other than through Intel Active System Console)?
Thanks,
Brady
