System testing must be performed to validate these conditionsand the specific system reactions are subject to change based on system testing.Note: If there is a fan fault on one PS, PMBUS FW would boost other fans on the faulty PS to100% PWM. Even if the fault is de-asserted, PMBUS FW would keep all fans at 100% PWM tillPS is reset either by AC cycle or removing and inserting back the PS.3.28.5 Power Supply Status SensorsFor each power supply, the BMC supports an IPMI type 08h power supply sensor using thefollowing offsets:Table 18. Power Supply Sensor OffsetsOffset00h01h02h03h06hDescriptionPresence detected – Asserted if power supply module is present. Eventsare only logged for power supply presence upon changes in the presencestatus after AC power is applied (no events logged for initial state).Event LoggingAssertion andDeassertionPower supply failure detected – Asserted if power supply module has failed. Assertion andDeassertionPredictive failure – Asserted if a condition that is likely to lead to a powersupply module failure has been detected, such as a failing fan.Power supply AC lost – Asserted if there is no AC power input to a powersupply module.Configuration error – Asserted if the BMC cannot access the servermanagement features due to a power supply type mismatch.Assertion andDeassertionAssertion andDeassertionAssertion andDeassertion3.28.6 Power Unit RedundancyThe BMC supports redundant power sub-systems and implements a Power Unit Redundancysensor per platform. A Power Unit Redundancy sensor is of sensor type Power Unit (09h) andreading type Availability Status (0Bh). This sensor generates events when a power sub-systemtransitions between redundant and non-redundant states, as determined by the number andhealth of the power sub-system’s component power supplies. The definition of redundancy ispower sub-system dependent and sometimes even configuration dependent. The BMC allowsredundancy to be configured on a per power-unit-redundancy sensor basis via the OEM SDRrecords. See Table 80 and Table 81.Revision 1.1Intel ® Confidential 49
