Note: The “+” and “-” signs represent the polarity of the wires that make up each wire pair.
C.1.2 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.)

C.1.3 Crossover Wiring
If the twisted-pair cable is to join two ports and both ports have the same indicator (MDI or MDI-X) 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 the straight-through or the crossover cable to connect to any device type.)

C.2 Pin Assignments for 1000BaseT Pin
All 1000BaseT ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.
