The ES-2008 has eight auto-negotiating,auto-sensing10/100Base-TX Ethernet RJ-45 ports. All these ports support auto-sensing, a built-in function that automatically recognizes the type (straight/crossover) of the attached cable. This feature effectively removes all wiring troubles caused by a cable type mismatch. Although a crossover cable is usually required to cascade a switch to another switch, auto MDI/MDI-X lets you use a normal straight cable to do the task.

The auto-negotiation feature allows the switch to detect the speed of incoming transmission and adjust appropriately without manual intervention. It allows data transfers of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
