The Critical, Major, and Minor alarm LEDs visible through the front door indicate whether a Critical,
Major, or Minor alarm is present anywhere on the ONS 15454. These L EDs mu st be v isib le so
technicians can quickly determine if any alarms are present. You can use the LCD to further isolate
alarms. See Chapter10, “Alarm Mon itori ng and Manage ment” for more information.
