UTP Port Pin Assignments
The UTP ports use RJ-45 Unshielded Twisted Pair (UTP) cabling. Connector
pin numbers and pin wiring assignments are listed below in Figure A-1.
Twisted-Pair cables can be wired with either straight-through or crossover pin
assignments. Both wiring schemes are mentioned in "Appendix B Cabling
Guidelines" for reference in creating a twisted-pair cable.

The UTP port labeled 24= is a standard straight-through UTP port.
All other UTP ports are configured as MDI-X, or internally crossed.
By default, all repeating and switched UTP ports are generally
configured as MDI-X, unless otherwise specified. See Notes on MDI
and MDI-X for more details.
