APPENDIX B

FE-100TX, FE-100FX AND FE-100F3

SPECIFICATIONS

The 6H122-08 supports three Fast Ethernet Interface Modules:

FE-100TX

FE-100FX

FE-100F3

This appendix provides the specifications for these modules.

B.1 FE-100TX

The FE-100TX uses an RJ45 connector supporting Category 5 Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms.

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-1shows the pinouts for the FE-100TX in both positions.
