The UTP/STP ports will automatically sense for Fast Ethernet (10Base-T/100Base-
TX) or Gigabit Ethernet (10Base-T/100Base-TX/1000Base-T) connection. Auto MDI/
MDIX means that the port can connect to another switch or workstation without
changing straight through or crossover cabling. See the figures below for straight
through and crossover cable schema.
