Straight-Through Wiring
If the twisted-pair cable is to join two ports and only one of the ports has
an internal crossover (MDI-X), the two pairs of wires must be
straight-through. (When auto-negotiation is enabled for any RJ-45 port on
these switches, 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.
