13.1.6 ALARM SETUP
The alarm setup feature enables operators to customize their alarms either by setting a preferred severity
(overriding the default level of severity) or filtering the alarm.
Lists all modules with their corresponding slot numbers in brackets
Allows for selection of a particular port, depending on the module selected under Slot.
Lists all possible alarms for the selected module in Slot. These alarms are all registered by
each module in the system. If no specific module is selected, all alarms are listed.
There are five possible options here:
• Set severity: Notify – Overrides the alarm’s default severity to Notify
• Set Severity: Warning – Overrides the alarm’s default severity to Warning
• Set Severity: Major – Overrides the alarm’s default severity to Major
• Set Severity: Critical – Overrides the alarm’s default severity to Critical
• Filter – Filtering is based on slot, port and alarm type. If an incoming alarm does not
pass the filter, the alarm is discarded. In other words, the alarm is not visible in the
Active Alarms node, not recorded in Alarm History, and not indicated on the LED of
the module itself.
The alarm filter page lists all the relevant alarms for the card type selected (if no specific card is selected all alarms
are listed). When an alarm filter is removed any active alarms which are filtered will re-appear with the
timestamp according to when the filter was removed.
The alarms shown in the alarm drop down list are all alarms registered by each module in the system. A module is
most often represented by a card. From the below list the ADM module equals an ADM decoder card. When an
alarm is raised by the respective module detecting an error condition it is possible for the module reporting the
alarm to override the alarm description, in order to add some extra information.
In some cases, this may cause the alarm text displayed in the alarm filter not to match the actual alarm text; but it
should be obvious which alarm it is.
The Alarm Filter also applies for the SNMP trap system.
