TWISTED-PAIR CABLE AND PIN ASSIGNMENTS

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 this switch, you can use either straight-through or crossover cable to connect to any device type.)

You must connecting all four wire pairs as shown in the following diagram to support Gigabit Ethernet connections.
