I'd say run lanscan to find the unit number of the card, and then run ifconfig to configure the card. (if you want to keep both cards in the machine).
You're going to have to take the server offline anyway (unless you are keeping both cards), so you could just replace the original card, then use ifconfig to configure it (lan0). If you're keeping both cards, configure it with another IP address, and connect it to the network. All depends on your network services.
Either way, man ifconfig, man lanscan, etc.
Also, you might need to edit /etc/rc.config.d/netconf
