How Do I connect a device, that has no screen, to my network?

[settingsun]

I assume a production server has no screen (headless). I've been building a server with a laptop. I installed fedora on it, gave it a static ip address and an ifcfg-eth0 configuration file, etc, and did all my work using its screen.

I'm going to buy production hardware, and set up the headless production server locally, using my home network - then send it to the co location host.

I used the laptop's screen to configure the laptop to connect to the network. I assume I will use the laptop screen to contact the headless server and configure it.

How is this done? How do I connect ( assign static ip, etc, so the network can talk to it) a server to my network when the server has no screen?

Thanks
