This read-only CucsEquipmentFexPsuInputStatsThresholded field is the 'thresholded' property of the 'FexPsuInputStats' managed object in Cisco UCS Manager's equipment-inventory schema for the FEX (Fabric Extender) subsystem indicating which of this PSU's monitored input fields crossed a configured alarm threshold. This narrows down exactly which of the PSU's input readings triggered an alarm, so an admin investigating a PSU fault knows immediately whether it was overcurrent, undervoltage, or overpower rather than having to check all three fields. A Thresholded value with only the voltage bit set points to an input undervoltage or brownout condition on that PSU's feed, even while its current and power stayed within range.
