APPENDIX B
FE-100TX AND FE-100FX SPECIFICATIONS
The 8H02-16 supports two Fast Ethernet Interface Modules:
•FE-100TX
•FE-100FX
This appendix provides the specifications for these modules.
B.1 FE-100TX
The FE-100TX uses an RJ45 connector supporting Unshielded Twisted Pair (UTP) cabling.
The slide switch on the FE-100TX determines the crossover status of the cable pairs. If the switch is on the X side, the pairs are internally crossed over. If the switch is on the = side, the pairs are not internally crossed over. Figure B-1 shows the pinouts for the FE-100TX in both positions.
