A major alarm (red) indicates a critical error condition that requires immediate action.

A minor alarm (amber) indicates a noncritical condition that requires monitoring or
maintenance. A minor alarm that is left unchecked might cause interruption in service
or performance degradation.

NOTE: The amber glow of the Alarm LED that indicates a minor alarm closely
resembles the red glow that indicates a major alarm.

All three LEDs can be lit simultaneously.
