ChangWang Q670-8Bay NAS Mini ITX motherboard upgrade version

Hi,

I recently purchased and installed subject motherboard.https://cwwk.net/collections/nas/products/q670-8bay-nas-mini-itx-motherboard-upgrade-version-lga1700-supports-intel-12-14-generation-processors-8sata-4m-2-ddr5-dual-slots-5x-usb3-2-8-sata3-0-ports-i226lm-2-5g-with-vpro

While all is running as expected I have major trouble to setup AMT via VPro.

1. There is no information about which of the 2 LAN ports is the i226-LM.

2. It seems as one of the LAN ports is disabled or not functioning (might be the i226-LM).

The LAN port next to the HDMI ports working and I get network connection but, even though AMT is configured correctly in the BIOS my Unifi router is not picking up the manual assigned IP address for AMT.

As soon as I plug the LAN cable in the 2nd port (adjacent to the usb ports) I don't get any network connection at all, the port seems not functioning.

Which of the 2 LAN ports is the vPro-port and is it possible that this port is deactivated or the Bios being corrupt/faulty and disabling port?

Is there a newer BIOS version then the one I currently have installed?
