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 connections.
