So does this mean that if the MAC internal network card is set to 1G, under the network setup last tab - and a 1G switch is used, then the whole network will run at 1G?

What happens about Artnet wanting to run at 10M? - will the switch automatically compensate?

Essentially we need the ability to move large files over a small network of catalyst servers using 1G speed, but also maintain the Art-Net control of the servers.

- Do I assume that a 2nd 1G network card is not needed? - and it's simply a case of changing the network settings to force 1G in conjunction with a 1G switch

Cheers
