This is a classic symptom of port speed/duplex negotiation problems. To verify, hard-code the port speed and duplex settings on both the switch and the card. You might have to try all possible combinations of hard-coding (e.g. hardcode switch but not card, then card, but not switch,and finally both). If this stops your random disconnects, you've solved the problem.

Ethernet port speed and duplex negotiation can have serious compatibility issues even between devices from the same manufacturer. I have both HP switches and HP servers and regularly encounter this problem. You're lucky that you're getting such a clear symptom; often you only get crummy performance.
