I am not sure if it has a DHCP address! Is there any way to identity its MAC address directly. I don't think it does - I set a fixed IP for the Ensemble and the C10 - but cannot see how to do that for the ID40. (I can remove everything else from the network, if I need to to work it out, I guess.)

When I reset the ID40 as per your earlier instructions, it said ID40 reset. The LED lights are flashing on the ethernet port too.
