of V

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).
Note: V

Power Faults are disabled in factory defaults.
