This enumerated field records which, if any, of the configured alarm thresholds for the blade motherboard input voltage/current values in this row have been crossed — such as an upper- or lower-non-critical or -critical voltage threshold configured in the associated power fault policy — and is what actually drives a UCS Manager fault or SNMP trap rather than the raw value alone. An admin watching this field can tell at a glance whether a number that looks high is still within the configured normal range or has already tripped a minor/major/critical threshold that needs a service ticket. For example, this field flipping from a normal state to an upper-critical indication is what would actually page an on-call engineer, even before they look at the raw measurement.
