This sensor is only supported for systems that use PMBus-compliant power supplies.The BMC reads current for the main 12 V power rail coming out of the power supply andexpresses the reading as the percentage of max rated output current for the power rail.This monitoring capability is instantiated in the form of IPMI analog/threshold sensors.IPMI Sensor CharacteristicsEvent reading type code: 01h (Threshold)Sensor type code: 03h (Current)Rearm type: AutoConfigured thresholds: Upper critical/non-criticalEvent generation: Assertion/deassertion events for all supported thresholds3.27.2.3 Power Supply Temperature SensorThe BMC supports two Power Supply Temperature sensors for each system power supplymodule. One temperature sensor uses in standby mode, the other uses in active mode. Thestandby sensors would be available only when the system in standby mode, reading for thesesensors in power on state would result in "reading not available" state. The active mode sensorswould be available only when system power on more then 25 seconds due to BMC delays 25seconds after DC Power On to access these sensors. Reading for these sensors in standbystate and power on less then 25 seconds would result in "reading not available" state. Moreover,the standby sensors and active mode sensors have different thresholds.These sensors are only supported with systems that use PMBus-compliant power supplies. Thismonitoring capability is instantiated in the form of IPMI analog/threshold sensors. The location ofthe physical temperature sensor in the power supply helps to provide a measurement of inlet airtemperature to the power supply. These sensors are implemented as auto rearm.3.28 Power Unit ManagementThe BMC supports IPMI type 09h, power unit sensor, using the following offsets:Table 14. Power Unit Sensor OffsetsOffsetDescriptionEvent Logging00h Power off – Asserted whenever the system DC power is off. Assertion andDeassertion04h05hAC lost – Asserted momentarily for event generation when AC power isapplied to the system and the previous system power state was on.Soft power control failure – Asserted if the system fails to power-on due to thefollowing power control sources:Chassis Control commandPEF actionBMC Watchdog TimerPower State RetentionAssertion andDeassertionAssertion andDeassertion44Intel ConfidentialRevision 1.1
