APPENDIX A
The 7H02-06 module uses Fast Ethernet Interface Modules
(FEPIMs) to provide front panel cable connections. The FEPIMs are
user-installable. See the section ‘Installing an FEPIM’ on page 3-1.
A.1 FE-100TX
The FE-100TX is 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 A-1 shows the pinouts for the
FEPIM-100TX in both positions.

A.2 FE-100FX
The FE-100FX shown in Figure A-2 supports multimode fiber optic
cabling. The FE-100FX is equipped with an SC style port.
Transmitter power specifications for the FE-100FX are listed in
Table A-1 on the following page.
