CABLES
Crossover Wiring
If the twisted-pair cable is to join two ports and either both ports are labeled with an “X” (indicating MDI-X) or neither port is labeled with an “X” (which indicates MDI), a crossover must be implemented in the wiring. (When auto-negotiation is enabled for any RJ-45 port on the 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.
