APPENDIX B
FE-100TX, FE-100FX, AND FE-100F3
SPECIFICATIONS
The 2E4X-27 supports three Fast Ethernet Interface Modules:
•
FE-100TX (
Section B.1
)
•
FE-100FX (
Section B.2
)
•
FE-100F3 (
Section B.3
)
This appendix provides the specifications for these modules.
B.1
FE-100TX
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.

NOTE
To ensure proper operation, use only Category 5 Unshielded
Twisted Pair (UTP) cabling that has an impedance between 85
and 111 ohms.
