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.
All three LEDs can be lit simultaneously.
