I have a networked device (an old motion controller) that I have connected to my network via a switch. My PC is connected to the same switch. This configuration works as expected and I can ping and open TCP connections to the motion controller.
However, if I swap the switch with some other models then I can no longer ping/access the device. I've tried two other (otherwise working) switches and the device doesn't work with either. Generally speaking isn't a switch just a switch? What differences can I look for between the switches to troubleshoot this?
The switches I've tried (all gigabit) are:
