Switching off 6400 causes LAN disconnection problem

m5kvk

I'm putting together what will become a remote QTH. Key to that is a Teltonika RUT-951 industrial router which is connected to a Raspberry Pi Station Control Computer, Geek Mini IT8 Windows 11 machine, and the Flex-6400.

In my initial bench setup, the radio was some distance from the router and other computers. Now that I am assembling it as it will be when remote, I've noticed that when the Flex is turned off (using the back panel RCA connector), I lose comms to the Windows PC and the Pi.

The RUT-951 is configured to ping the Pi and reboot if it fails to a response 5 times over a 10 minute period, so the station recovers, but it is annoying.

Has anybody experienced this?

Is the router busy and hung up on dealing with a port that has gone away? Not usual switch behaviour, that’s for sure.

Maybe look at what the router is configured to do when a ports stops responding.

Also maybe a firmware update is available for the router?

Thanks, both

There's nothing in the router log - not even a report that the port disconnected. Firmware is current.
