Administration – Fault
The Fault tab under the Administration category provides configurable selections indicating the way to
notify when a Power, N-Ring Manager, N-Link fault, or Port Usage Fault occurs. The notification may
consist of any combination of the options: Show Web, Show LED, and Contact.
With a low voltage DC power supply installed, the Power signal faults will consist of V
1
and V
2
.
N-Ring Manager signal faults consist of: Broken, Partial Break (Low), Partial Break (High), and Multiple
Managers. N-Link Faults are reported by the N-Link Master and by the N-Link Slave. Port Usage Fault, if
enabled, triggers when actual usage is below the Usage Alarm Low setting, or above the Usage Alarm High
setting (see Port Configuration View and Port Utilization View).
The example below shows the Fault Configuration View on a switch with a low voltage DC Power supply
installed.
Note: V
1
and V
2
Power Faults are disabled in factory defaults on a low voltage DC power supply.
