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.

cabling. The FE-100FX is equipped with an SC style port.
