Alarms & Events
TimeProvider 100 reports alarms and events related to hardware failures.
Non-alarm events are changes in system configuration and operational mode.
TimeProvider 100 records alarms and events in the Event Log. Up to a 1,000 entries
can be logged, and the oldest entry is deleted first when the log is full.
all alarms, events, and default settings. Event code number 20 (Configuration
Change) includes all the changes to system configuration that are not listed in the
table.
Level
Level identifies the severity of the alarm. It can be critical, major, minor, or event. If
the level is event, it is not reported, but it is recorded and logged. The events
defined in the table (code 20 and 24–29) cannot be changed to alarms. Alarm codes
0 –19 can be changed to events and back to alarms. If an alarm happens, and its
transient parameter is "no," it will be reported as an active alarm. A SNMP trap will
be generated, and the trap will be logged in the Event log.
