External Alarm Settings 
This window is used to display and configure the external alarm settings. This is used to enable monitoring the 
external alarm source status or to configure external alarm message for a channel. The source of alarm is located 
outside of the Switch and is monitored via pre-defined connecting channels. Each channel represents a specific alarm 
event. The status of an alarm source can be either in the alarm state or in the normal state. If the source is absent or 
the source is present and in the normal state, the status will be normal. The status will be abnormal if the source is in 
the abnormal state. A notification will be sent when the monitoring status is changed. 
To view the following window, click Monitoring > External Alarm Settings, as shown below:
