The Alarm LEDs on the CPM/CCM reflects the current status of the Facility Alarms:
The Critical Alarm LED (if available on the 7210 SAS platform), is lit if there is 1 or more active Critical Facility Alarms.
Similarly with the Major and Minor alarm LEDs (if available on the 7210 SAS platform).
The OT Alarm LED (if available on the 7210 SAS platform), is not controlled by the Facility Alarm module.
The supported alarm severities are as follows:
Critical (with an associated LED
Major (with an associated LED
Minor (with an associated LED
Warning (no LED)
Alarms inherit their severity from the raising event.
Log events that are a raising event for a facility alarm configured with a severity of "indeterminate" or "cleared" will result in those alarms not being raised (but clearing events are processed to clear alarms regardless of the severity of the clearing event).
Changing the severity of a raising event only affects subsequent occurrences of that event and alarms. Alarms that are already raised when their raising event severity is changed maintain their original severity.
