Hello Guys,
Thank you all for your replies.

I'm only using Options for the Default Gateway, DNS-Server and Domain-Name. I don't use Option 43 or 125.

In the Server.log file there was only this one line written:
2017-09-12 09:09:00,271 ERROR [com.ets.netsight.inv.server.webapps.monitor.InventoryDwr] Error retrieving Device Records for DeviceType: null ex:null
which lead me to the following KB article:
https://gtacknowledge.extremenetworks.com/articles/Solution/Unable-to-find-Saved-device-configuratio...
Since this is about ZTP and not ZTP+ I think I can ignore this Error.

I should have done everything according to this article.
I Pre-registred the Device but in EMC the Status field in the Discovered Tab won't Change form ZTP+ Staged.
Kind Regards
Michael
