networking

Hello,

Not sure if this is the right place to ask this question. But I have a router which connects to the internet. Now I have a switch connected to this router. I added a lot more computers so I added another switch and connected it to the first switch using a cross-over cable.

As soon as I connect it to the first switch, my lights in first switch start blinking like crazy and my entire network simply stops working. The minute I remove the second switch's wire, its all fine again.

What could be the problem?
