[CAUSE] A tmnxSasAlarminput3StateChanged notification is sent when status of the alarm input on pin three(3) changes. When this notification is sent, the field tmnxSasAlarmInputNotifyMessage is populated with either the tmnxSasAlarmInputTriggerMessage when the alarm is raised, or the tmnxSasAlarmInputClearMessage when the alarm is cleared. The trigger or clear actions depend on the polarity of the input as defined in tmnxSasAlarmInputPolarity. [EFFECT] A desirable or undesirable event has occurred in the external equipment connected to the alarm input. Hence the characteristics of effect and the associated risks vary depending on the nature of the external equipment being monitored over the alarm input. [RECOVERY] Check the external equipment, connected to the alarm input pin three(3), that resulted in this alarm and rectify the problem.
