An enumerated code identifying which temperature-threshold condition, rising above or falling below upper critical or non-recoverable limits, triggered this notification, for either analog airflow sensors or digital power-supply sensors. It tells the admin whether a temperature alarm is from an inlet or outlet airflow sensor or a power supply's internal digital sensor, and how severe the crossing is. A trap carrying csOrionTemperatureEvent equal to tempRisingAboveUpperNonRecoverableThreshold(3) signals an admin that a power-supply digital sensor hit its most severe temperature limit, warranting immediate shutdown consideration.
