Extron Electronics VN-Matrix 200 Series - Manual (Page 92)

Alarm Type
This drop-down menu lists the available alarm error conditions for all units. Alarm error
conditions are divided into two categories:
• Alarm errors that occur on an encoder
• 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 filters may be set for either a single, specific unit or for all VN 200 devices in the
system.
Alarm Severity
Alarms may be set to one of three severities.
Alarm Severity Description
Critical When triggered, a critical alarm will illuminate 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 traffic 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
Changes made to the Filter Settings may be applied from the Apply Filter Change
button.
Changes made will be lost after a power down unless the
Save All tab is used 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.
