Intel® Telco Alarms Manager 2.3 Modes, Models, and MappingAppendix A: Glossary
Revision 1.7 9
• Most Severe Alarm Model – Only the most critical alarm LED is illuminated. For
example, if a minor alarm is present and a major alarm occurs, the minor alarm data will
be retained in the alarm database; only the major alarm LED will be illuminated. If the
condition that set the minor alarm previously still exists when the major alarm is cleared,
the minor alarm will once again become illuminated. The “Most Severe” model is the
default alarm model.
• All Severities Alarm Model – All alarm LEDs for which alarm data exist will illuminate.
This behavior facilitates the illumination of multiple LEDs simultaneously.
5.3 Alarm Severities
Severity modifications are dependent upon the Event Agent’s configuration. The Event Agents
analyze events from the hardware and software applications, and map the sensor severity to a
Telco Alarm severity. The Event Agents then make calls to the TAM with the alarm information
for alarm table entry and LED illumination. Table 1 lists descriptions for each alarm panel LED.
Table 2 lists how the ISM, ISMS, and SNMP Event Agents’ severities map to TAM LED
severities.
Table 2. TAM LED Descriptions
TAM Alarm Panel LEDs Description
MINOR (MNR)
A non-service-affecting condition.
Corrective action should be taken in
order to prevent a more serious fault.
MAJOR (MJR)
A service-affecting condition that
requires an urgent action.
CRITICAL (CRT)
A service-affecting condition that
requires an immediate action.
POWER (PWR)
Only active for power or voltage
events.
DISK (DSK) Activated during disk activity.
(NIC) Activated during network activity.
(ON)
Activated when system is powered
on. Not activated when system is
powered off.
