4.1Dual-Speed Functionality, and Switching

The LP004A Series Power over Ethernet (PoE) Switch provide four switched ports (three ports in the front and one on the rear). The architecture supports a dual speed switching environment, with standard auto-negotiation capability.

The switched RJ-45 ports are full- or half-duplex auto-sensing for mode and speed, and auto-cross for plug polarity. When the connected device is 10 Mbps, the LP004As obeys all the rules of 10 Mbps Ethernet configurations. The 10 Mbps users can “communicate” with 100Mbps users as well as other 10 Mbps users through the switch. Similarly, the 100Mbps traffic obeys the rules of 100Mbps Ethernet, and can communicate with 10 Mb and 100Mb users.
