I connected my Router 2503 to my Switch Cat 1900. I took the advice of several others in the room, by using a transceiver to the AUI port on the router and used a straight through cable to the Switch. Unfortunatly there was no green light. On the Router, I gave the port an ip address and typed no shutdown. Was there any configuration I needed on the switch. Aslo how can I get my laptop on to the Switch? Or any other nodes?
