Converter Card states and -48V Input Feed states are aggregated and combined into a Converter Shelf
state.
Converter Shelf states and Fan Shelf states are aggregated and combined into a Converter system
state.
•
System Alarm State - the highest alarm state within the system, including Converter Shelves and Fan Shelves.
•
Shelf Alarm State - the highest alarm state within the shelf, including Converter Cards and -48V Input Feeds, Fan
Shelf state (if wired), and Alarm Card I
OK No alarms are active – all OK
PMN Minor alarms only are active

OK No Fan Shelves have alarms are active – all OK
Minor One Fan Shelf has alarm active
Major Two Fans Shelves have alarms active
•
