Fault Relay Alarm
The Fault Relay Alarm function provides the mechanism for warning when power or port
faults are detected. There is a set of relay contacts in the switch, and the contacts are
closed when either no fault alarms are configured, or the system is normal. With the
check boxes unchecked, the system won’t change the status of the relay when a fault
occurs. Please see the segment of ‘Wiring the Fault Alarm Contact’ for reference. With
both power input 1 and power input 2 installed and the check boxes of power 1/power 2
ticked, the FAULT LED indicator will then be possible to light up when any one of the
power fault occurs. As for the Port Link Down/Broken detection, the FAULT LED
indicator will light up when the port fault occurs.
Power Failure: Tick the check box to enable the function of lighting up the FAULT
LED on the panel when power fails.
Port Link Down/Broken: Tick the check box to enable the function of lighting up
FAULT LED on the panel when Ports’ states are link down or broken.
