Configuring alarm relays
Industrial rugged switches have hardware alarm ports that generate an alarm on internal or external
condition depending on alarm port wiring during system installation. The switch provides for 1x output
alarm port that could be wired to an external device. When an external device like an external alarm bell is
wired to the output port, configuring the event to output relay will trigger the bell to ring indicating the
event. These events could also be configured to send syslog messages and SNMP traps. The switch also
provides for 2x input alarm ports. An external device like a door or a sensor could be connected to the
switch which can be configured to trigger a syslog or SNMP. These could also be forwarded to the relay
circuit at the alarm output port.
To configure the alarm relays, refer to the following CLI commands.
For additional CLI and
software information, see the
Monitoring Guide
for your switch.
