6.3 Ethernet Connectors (ETH1/ETH2) (J8)
The KTA70M supports two 10/100/1000Mb Ethernet RJ45 connetors in a stacked dual LAN connector, type
Ude RMT-123AGF1F or sililar. Both ports are driven by Intel® Pearsonville WGI211AT PCI Express controller.
Ethernet connector 1 (ETH1) is mounted above Ethernet connector 2 (ETH2).
