The DPE-301GS Po E splitter is used with end devices such as wireless access points, IP cameras & Vo IP phones that don't natively support Po E, but rather require DC power input. It receives Po E power on a network cable from a Po E switch or midspan injector, and splits the Ethernet & DC power into two separate cables. One cable provides the DC power, and the other cable provides the Ethernet signal. The DPE-301GS Po E splitter has two 10 / 100 / 1000 RJ-45 ports. One port is for Po E input, which is the network connection & is usually connected to a remote Po E switch or injector. The other port is for LAN output, which is the connection that provides the Ethernet signal to the end device.
