2.2.2 The Ethernet Connections
Auto-Sensing 10/100Base-TX RJ-45 Ports (Auto MDI/MDIX)
The ES-2008 has eight auto-negotiating, auto-sensing 10/100Base-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.
Auto-Negotiating 10/100Base-TX RJ-45 Ports
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.
