You need to define static IP's in darcut format ‎on the kernel boot command line now since 7. Look at the kickstart instructions for fedora for details.
Right or wrong the idea behind it is that with IPv6 ‎coming in the future every one should be using DHCP every where.

Peter,

Did you solve your problem? I'm going to be doing an http install of 
CentOS 7 tomorrow on a subnet with no DHCP server, and I'll see where 
configuring the static IP is in the installer (I'm pretty sure I know 
where it is; there is a configure button on the Network & Hostname page 
of the installer, and configuring a static IP is done there).

There is no dhcp available in that environment (Hetzner root server in Germany). With previous installation I remember the installation started nevertheless and I could configure a static IP configuration as part of the installation process. Unfortunately, I didn’t found any opportunity to define a static IP prior to the installation process aborting.
