Watchdog failure actions
When the CX-6p-PoE fails to receive a number of consecutive pings from the
target device, it will trigger the AUX contact output for a time period determined by the
Aux Time setting. This output is intended to be used to trigger an alarm buzzer or light,
or to cycle power on a small DC-powered device. The contact is rated for 42 volts, up to
1 Amp current, and should not be used to switch line voltage or any device which draws
more than 1 Amp.
The CX-6p-PoE can also optionally send a TCP message of up to 40 characters
to a target address on the network. IP:PORT indicates the network IP address and port
of the target device. This may be up to 24 characters long and must consist of an IP
address in dotted-quad format, followed by a colon, followed by a port number in the
range of 0 to 32767. The default setting of “0.0.0.0
:23 ” indicates no action to be taken.
The TCP Message field holds a text message of up to 40 characters. When a
lack of ping response occurs, this message will be sent to the specified network address.
The Email Message field holds a text message up to 80 characters long which
will be sent to the email address specified in the IP Ethernet Setup screen. If a message
is specified here, it will be sent to this address when a watchdog failure occurs.
The watchdog function can also be configured to toggle power on one of the PoE
power providing ports on the CX-6p-PoE. When the specified device is not responding
to pings, the CX-6p-PoE will disconnect power to the device for 5 seconds. This can be
used to power-cycle a device which is being powered by the CX-6p-PoE.
The Test Restart button is used to manually trigger a Watchdog reset. This will
trigger the aux output to occur, and if specified will trigger a TCP message to be sent
and an Email notification to be sent.
