RJ-45 Pin Assignments
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.
