Network path / four lanes

Three i226-V, one RTL8156B.

The PoE option sits on the same four-port stack; the 9–36 V rail feeds the board from a single DC jack.

Applications / network edge

Ports where the cabinet meets the network.

Network appliances and gatewaysThree i226-V ports and one RTL8156B separate WAN, LAN and service traffic.
Energy cabinetsThe 9–36 V input takes a wider rail; PoE can power a camera or access point from the same board.
Video analytics nodesFive COM headers and 8-bit GPIO connect meters, relays and panel signals.
