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

We recommend connecting all four wire pairs as shown in the following
diagram to ease an upgrade to Gigabit Ethernet.
