B-4Crossover Wiring

If the twisted-pair cable is to join two ports and either both por ts are

labeled with an “X” (MDI-X) or neither port is labeled with an “X”

(MDI), a crossover must be implemented in the wiring. (When

auto-negotiation is enabled for any RJ-45 port on this switch, you can use

either straight-through or crossover cable to connect to any device type.)

You must connect all four wire pairs as shown in the following diagram to

support Gigabit Ethernet connect ions.
