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.)

Crossover Wiring

If the twisted-pair cable is to join two ports and either both ports are labeled
with an "X" (MDI-X) or neither port is labeled with an "X" (MDI), 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 straight-through
or crossover cable to connect to any device type.)
