RJ-45 Port Pin Assignments
All RJ-45 ports on the Gateway support automatic
MDI/MDI-X configuration. This means that the pin signals
in use will depend on whether the port is operating in MDI
or MDI-X mode.
Figure B-1 illustrates how the pins on the RJ-45 connector
are numbered. Be sure to hold the connectors in the same
orientation when attaching the wires to the pins.
