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.
