FE-100TX, FE-100FX AND FE-100F3
SPECIFICATIONS
The 6E12X-26 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-1
shows the pinouts for the FE-100TX in both positions.
