7. RJ-45 PIN ASSIGNMENT
When connecting your FNSW-3200 10/100Mbps Ethernet
Switch to another switch, a bridge or a hub, a straight or
crossover cable is necessary. Each port of the Switch supports
auto-MDI/MDI-X detection. That means you can directly con-
nect the Switch to any Ethernet devices without making a
crossover cable.
The following table and diagram show the standard RJ-45 re-
ceptacle/ connector and their pin assignments:
