VN-Matrix 300 • Alarms and SNMP 61
Alarm Type
This drop down lists the available alarm error conditions for all units. Alarm error conditions
are divided into two broad categories
z Alarm errors that occur on an Encoder
z Alarm errors that occur on a Decoder
In addition there is one alarm error that only occurs on the device that is configured as the
system controller.
Alarm Source
Alarm lters may be set for either a single, specic unit or for all VN-Matrix 300 devices in
the system.
Alarm Severity
Alarms may be set to one of three severities.
Alarm Severity Description
Critical
When triggered, a critical alarm illuminates the red LED on the front
panel of the affected unit. In addition, the normally open contacts of the
relay accessed via the COMM 2 connector will be closed.
The traffic light indicator for the device (Device list) will be shown in red.
Warning When triggered, a warning alarm will result in the trafc light indicator
for the device (device list) showing in amber.
None
A setting of None effectively filters the alarm condition. The alarm will
still appear in the alarms list but it will not affect any colored indicators.
Alarm Reporting
An alarm condition may be either reporting or not-reporting.
A reporting condition will cause an SNMP trap to be sent to an SNMP client whenever that
alarm condition is triggered.
Applying Alarm Filter Settings
z Changes made to the filter settings may be applied by clicking Apply filter change
button.
z Changes made will be lost after a power down unless the Save all tab is clicked to
make these changes permanent.
Alarm List
The Alarm list provides information on all alarm events that are currently active. The list is
refreshed each time the Alarms tab is selected.
Alarm events that are listed may be sorted by Type, Raise time, and Severity.
Position the mouse pointer over the required sorting heading (Type, Raise time, or Severity)
and left click to change the list order. The list will be refreshed each time the sorting criteria
is applied.
