Complete set for wide range of network products such as Access Points, Routers, IP cameras, modems,switches, embedded computers or other network devices such as D-Link, Ovislink, Senao, Wline, RouterBOARD, WRAP boards and other devices using passive POE injection.

It is very simple to connect a passive PoE. On the lower part, we connect the Ethernet
RJ connector of passive PoE to the PC, Hub or Switch and connect the power adapter to the power socket.

On the opposite end (RJ socket) we connect the Ethernet cable leading to the far end.

At the far end, we connect the end of the Ethernet cable to the RJ socket and connect the power connectors and the Ethernet to the powered equipment. The equipment is now connected by them.
