Ethernet Ports
RJ-45 Ports
(Auto MDI/MDIX)
The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX or
1000Base-T devices connections. Auto MDI/MDIX means that
the switch can connect to another switch or workstation
without changing the straight-through or crossover cabling. See
the figures as below for straight-through and crossover cabling
schematics.
