Fault Page
The page provides configurable selections indicating the ways to notify when a Power, N-Ring Manager,
Port Usage, Temperature, or Configuration Device fault occurs. In each case, the notification may consist of
any combination of the options: Show Web, Show LED, and Contact.
Fault Contact:
Determines if the fault relay is normally open (Close on Fault) or normally
closed (Open on Fault).
