2 Types of Alarm Indicators
When the OAM system is configured as described in Chapter 3 of the iMAP User Guide, indicators for faults
or potential faults are easy to generate, store, and output. The OAM system produces the following event and
alarm indications: logs, Traps, and LED alarm indicators. These events are described in more detail below.
2.1 Alarm Severity
Allied Telesis system alarms are organized by order of severity level. They are Critical, Major, and Minor. Each
level is described here.
2.1.1 Critical
Critical is the highest, most severe level of alarm. An alarm with a severity level of critical means that system service is being
detrimentally affected. It requires the user’s immediate attention.
When a critical alarm conditions is raised, the CRIT LED on the CFC faceplate will be illuminated. An LED on a card face-
plate may also be illuminated.
A log indicating a critical alarm will be prefaced by “*C” as the first two characters in the first line of text. An example of a
critical alarm log is shown below.

2.1.2 Major
Major is the second highest level of alarm. An alarm with a severity level of major means that system service may be affected.
The user must immediately investigate a major alarm.
When a major alarm conditions is raised, the MAJOR LED on the CFC faceplate will be illuminated. An LED on a card face-
plate may also be illuminated.
