With servers, it's always best to give them a static IP address when connecting to the network. This means that you have to set the appropriate server IP address as well as default gateway and domain name system. To do this, click on "Ethernet" and the Network Connection windows will open.
Choose the adaptor you wish to change the IP address on by double clicking on it. This will bring up the information page. Double-click on "Internet Protocol version 4". This will bring up another box where you can type in the correct details for your server's address.
