RJ45 Ports
RJ45 Ports (Auto MDI/MDI-X): The RJ45 ports are auto-sensing for 10Base-T, 100Base-TX, or
1000Base-T connections. Auto MDI means that the switch can connect to another switch or workstation
without changing the straight-through or crossover cabling. See the figures below for straight-through and
crossover cabling schematics.
