Extron Electronics VN-Matrix 250 User Guide - Manual (Page 44)

Alarms can have three degrees of severity indicated by the alarm icons in the device list and
the alarm status messages at the top of each page:
z
Critical is shown in red and usually means the service has failed. If the device has a
critical alarm it illuminates the red LED on the front panel and activates the closure relay
accessed by the rear panel connector.
z
Warning is shown in amber and indicates a less severe error has occured. Often a
Warning is raised when there is an expectation that another Critical alarm shows the
root‑cause of the problem.
z
Setting the severity to None effectively filters this alarm ‑ it still appears in the alarms list
but does not affect the colored indicators.
Alarms can also be Reporting or Not-Reporting. A Reporting alarm will cause an
SNMP trap to be sent to any registered SNMP client when the alarm is raised. Setting
Not‑Reporting prevents these traps from being sent.
Alarms can be filtered for all devices or for just a single device. This is achieved by Selecting
the
Alarm-Type , Alarm-Source , Alarm-Severity , Alarm-Reporting and clicking
Apply Filter Change . Note that if a global change is made this will not affect any devices
which are created after this time. All devices are always created with default severities and
reporting.
Alarm logs tab
From the Alarms tab, click the Alarm Logs tab:
Figure 23. Alarms Logs Tab
An Alarm Log is a record of when an alarm condition was raised and when it was cleared.
Alarm Logs are paired so an Alarm Log with both a raise time and clear time describes a
historic alarm condition.
