"status: no carrier" when you do an ifconfig indicates a layer 1 or 
physical problem. You need to try plugging in each of the other ethernet 
ports on that server and checking ifconfig to see if the status changes. 
As obvious as this seems (and sorry if you've already tried this) I have 
some supermicro servers with Intel nic's and FreeBSD 5.3-R has them 
mixed up. The ports are labeled 1 and 2 on the case but FreeBSD calls 
ethernet port 2 em0 and ethernet port 1 em1. Maybe that is what you are 
seeing here.
