10/100BASE-TX Fast Ethernet Switched Ports

Each switched port supports one connection to a LAN segments. Each segment is an independent shared network in one collision-domain. The connection can be to either a 10BASE-T or a 100BASE-TX device.

MDI-X and MDI RJ-45 Connectors

MDI-X jack is labeled [X] normally to indicate the jack is designed with internal crossover function. It allows a connection to an end station using straight-through UTP cable. MDI RJ-45 connector is provided for easy uplink via standard straight-through UTP to other device that supports MDI-X RJ-45 connector. The following table shows the pin assignments of MDI-X and MDI RJ-45 connector respectively:
