Tree ethernet shield in network

Hi guys, I have tree Arduino ethernet shield and I would Like to send all their informations in one computer. So i used one " Switch". My broblem are these:

  • shield does not communicate properly: sometimes communication light (3 orange led ) appear and disappear and cables are good.

  • how can I get all the tree IP address of every shield?

Note: the shield+Arduino is just used as transmitters !!

Need help, and I am open if you need more informations !!! Thanks
