I am trying to hook up a Cisco 2950 Catalyst switch. I have run cat5e straight-through from the router to the switch. I toned and tested the cabling. It is working fine. However, when I plug it into the switch, the server can't see the network. I tried plugging the Ethernet into port 1, then into the console port on the back of the switch. No network. But if I plug it directly into a workstation, I can immediately get onto the Internet. I've tried replacing the switch, but that didn't help either. Any ideas?
Because you are connecting from the 3Com hub to the Cisco switch you will need a cross over cable to connect these two devices.
From router to hub can be straigh-thru then from hub to switch make it a cross-over.
