RJ-45 ports

There are 6x 10/100Mbps auto-sensing ports for 10Base-T or 100Base-TX devices connection. The UTP ports will auto-sense for 10Base-T or 100Base-TX connections. Auto MDI/MDIX means that the switch can connect to another switch or workstation without changing straight through or crossover cabling. See the below figures for straight through and crossover cable schematic.
