Hello,

is it possible to use a GPeR-repeater with one device POE out on the one side, and the other device with "nothing", I mean without any POE?

Al the diagram I see, they use on the one site POE out and on the other side POE in....

Yes, you can remove jumpers on PoE-out side and then it won't pass PoE further.
But there is a note, that it won't work if 802.3af/at is used - the power source device won't power the GPeR alone.

Great, thanks. All the information was there ;-)

Do you know guys why GPeR can't be powered by 802.3af/at itself? I'd like to extend the link between two switches, however in that situation it isn't possible to use GPeR.

You could use RBGPOE passive injector from one side to power GPeR ... I guess.
