No network after fresh install

[mammutserver]

Hello community, I installed Proxmox on a Supermicro CSE-826 but the network connections doesn't work...
The link and active led's are not lighting up/blinking and I can't get any network connection. I tested the networkcable with my pc and it is definetly working. I also did some research on Google and found no solution for my problem.
Can anyone assist?

- add these lines to '/etc/modules':

vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd

- After changing anything modules related, you need to refresh your initramfs.
On Proxmox VE this can be done by executing:

# update-initramfs -u -k all

- reboot host (maybe twice)
