Watchdog
The CX-6p-PoE has a watchdog function which can be used to monitor up to four
network-connected devices for failure, and perform user-configurable actions when that
device fails to respond.
When the Watchdog feature is enabled, the CX-6p-PoE will send ping requests
to the target IP address at a frequency determined by the Interval setting. The CX-6p-
PoE will wait for a period of time determined by the Timeout setting for a response to
each ping message. If it does not receive a ping response for a ping, it will increment a
counter which records the number of consecutive failed pings. A single successfully
received ping response will set this counter to zero. When a number of failed ping
responses equal to the Failures setting has occurred, the unit will take some action as
determined by user settings. It will then wait for a number of minutes determined by the
Restart Delay setting before sending any more ping messages.
