I just plugged a brand new server into a Bay Networks 10/100 24-port hub and the collision lights went crazy. I tried new cables and got the same thing. But when I move the cable to 2 or 3 specific ports, the hub looks fine with no collision lights. I have moved several other systems around on the hub but they do not cause any amber lights. Plugged the new system into a second Bay Networks hub (stacked with the first hub) and got collisions again.
Initially, I thought the NIC was bad (or headed that way) even though it was new. When problem wasn’t consistent on all ports, I thought I might have ports going bad on that hub. But when I got the same problem on a different hub, I went back to thinking it was a bad NIC.
Here’s the questions: 1) The server and its NIC look OK on a few ports; Is that normal and I should just find a port it works on and not worry? 2) The NIC is builtin on the motherboard and under warranty; should I have the motherboard swapped out before I build the server up?
