Fault
The Fault page provides configurable selections indicating the different ways to notify an administrator when a fault
occurs. In each case, the notification may consist of any combination: Show Web, Show LED and/or Contact.
Some fault configurations are only available under specific conditions. For example, Power AC is only available
when an AC power supply is installed in the switch. N-Ring
™
faults are only available when the switch is set to
N-Ring Manager mode. The page below is an example of what may be seen on the Fault dialog window.
Additionally, when a fault is triggered, an event may be generated at the severity selected by the user. The event
will be logged unless it is filtered by the Event Log Filter.
The event’s severity can be set to any of the following values.
Note:
These are based on the Event Log's Severity:
•
Emergency
•
Alert
•
Critical
•
Error
•
Warning
•
Notice
•
