# Alarm Status Levels

The system's alarm status is displayed on the top-left corner of the System Administration screen. The time and date next to the alarm status indicates when the last alarm was raised or cleared. The date and time may not be related to the alarm status. Alarm status is also indicated on the front of the controller. The 3300 ICP controllers use a single tricolor LED. The colors are defined below.

There are four classes of alarms: CRITICAL, MAJOR, MINOR and NONE. Some of the alarm threshold levels are programmable. The following describes the various alarm classes. The color in brackets [color] indicates the color for single alarm LED systems.

Critical LED - [Red] | This is a total loss of service which demands immediate attention. A critical alarm invokes system-fail transfer. This LED is on when there is a critical Alarm, during Power Up, Reset or initialization, or when the license violation level is Critical or System Lock.
Major LED - [Orange] | This is a fault which affects service to many users. This may result in a major degradation in service and needs attention to minimize customer complaints. This LED is on when there is a major alarm, during Power Up or Reset, or when the license violation level is Major. NOTE: An alarm level Major (Unreachable) indicates that the MiVoice Business system element is down.
Minor LED - [Yellow] | A minor alarm is any fault which does not fall in either of the above two classes. Whenever the system is not 100% operational, a minor alarm is raised. This may require the attention of a crafts person but is not urgent. Examples of a minor alarm include the loss of a single line or trunk circuit or the loss of one circuit switch link. This LED is on when there is a minor Alarm, during Power Up or Reset, or when the license violation level is Minor.
All off - [Off] | No active alarm, or when the license violation level is Clear or Warning.

NOTE: A minor Fan, Power Supply, or RAID alarm in the MXe III means that only one of the components has failed. A major alarm means that both of the components has failed.
