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.
