If the twisted-pair cable is to join two ports and either both ports 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.
