This is a working auto-integration file for RBS 6402 with Open5GS

Power on radio using a 48 volt power source, don't use PoE

Make sure there is an SFP installed in port B, and your computers IP is set to 10.1.1.0/24 Range. The radio MGMT interface is 10.1.1.11

You will need to follow the Auto Intergration instructions in the PDF, and genereate several certifaces and a trusted CA as well. 

After that you will use the combined XML file that goes with your radio. Fill out the information that you need. Mainly MCC/MNC, EARFCN, MME IP, NTP Servers. You will paste in your ssh key you generated
and you will set SFTP paths for your trusted CA and user cert. I use TinySFTP server for this. You will also need to have the firmware files in the SFTP server as well. 

Load the webui, and choose SFTP option, and enter the path to your SFTP server root that has the combined XML file.

It will load the file, if all goes well the intergrate button will ungrey, hit intergrate, it will restart, and if it worked you will have two solid green lights. 

This is the very short edition of how to do this. Read the PDF for better information.
