Ethernet
The kit features two 1Gbps copper Ethernet ports. While the first ethernet port is implemented fully onboard CL-SOM-iMX6 module, the second port is implemented onboard SB-FX6 using the PCI-Express port available with CL-SOM-iMX6. Both ports are exposed through the P9 Dual RJ45 connector.
Primary Ethernet
The primary Ethernet port (also referred to as CM Ethernet, SOM ETH or Module Ethernet) is available through the left side of the dual RJ45 connector P9 (also called (P9A).
Secondary Ethernet
The secondary Ethernet port (also referred to as SB Ethernet, SB ETH or 2nd Ethrnet) is available through the right side of the dual RJ45 connector P9 (also called P9B). The P31 jumper setting determines whether the CL-SOM-iMX6 PCI-Express interface is utilized for the secondary ethernet port (Ethernet is available through P9B) or for the P40 mini-PCIe socket (Ethernet is not available through P9B) onboard SB-FX6.
