we prefer English language here, so I will reply in English. A short translation first of your issue:
If I want to add multiple network adapters (DHCP - Ethernet), the UCS always hangs on the second adapter. Example: Quad-port network card first port can be added immediately and without problems, second port UCS hangs with the message “Setting up IPvX network devices”.
Already tried several external (different) cards, the cards and NICs were all correctly detected and displayed during installation. When configuring the second NIC of a quadport card, however, it unfortunately never goes further.
Where can I find the UCS logs for the network settings I would have made?

Before checking if this is an issue of UCS I would try to configure the interfaces first manually.
Check the naming for your interfaces by
WARNING: systemd-networkd is not running, output will be incomplete.
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback n/a unmanaged
2 ens192 ether n/a unmanaged
3 docker0 ether n/a unmanaged
3 links listed.
Now you can configure your additional interfaces manually ie with ifconfig:
ifconfig ens193 192.168.192.42 netmask 255.255.255.0 up
Once it is up you should be able to
ping any host in this network which indicates the network card itself is running fine.
Once confirmed it is running fine you might configure your additional interfaces through ucs-variables as follows:
ucr set interfaces/eth1/address: 192.168.9.10
ucr set interfaces/eth1/broadcast: 192.168.9.255
ucr set interfaces/eth1/ipv6/acceptRA: false
ucr set interfaces/eth1/netmask: 255.255.255.0
ucr set interfaces/eth1/network: 192.168.9.0
ucr set interfaces/eth1/start: true
ucr set interfaces/eth1/type: static
Check documentation if you prefer to set one of the interfaces to use a DHCP-assigned address.
