Have developer license but need to use license on private lan server how to ?

Hi , i have nearly finished my project on my workstation.Which has license of objectdb activated because its internet connected.

But now i need to copy my project to LAN server which is private LAN.

So how to activate server license ? 

I have Site Licences

You can also run the activation process without an Internet connection. A link will be displayed in the console. Open this link on another computer that has Internet access to obtain an activation code for the offline machine.
