Appendix A Pin Assignments
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 and
Table A-1, respectively. 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.

U T P P o r t
The UTP port labeled MDI 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 page 7 Notes on MDI and MDI-X for details.
