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.
Each UTP port is configured as "MDI-X", or internally crossed.
By default, all repeating and switched UTP ports are generally
configured as MDI-X, unless otherwise specified. The last UTP
port (port 5 on the KNS500/WG and port 8 on the KNS800/WG)
is linked to a cascade switch that allows it to support UTP
cabling in the straight-through (MDI) and crossover (MDI-X)
wiring configuration. See page 7 "Notes on MDI and MDI-X" for
details.
