FEPIM Specifications
The 9H423-28 SmartSwitch 9000 module uses a Fast Ethernet Interface Module (FEPIM) to provide front panel cable connections. FEPIMs are user-installable. See the section titled Installing an FEPIM in Chapter 2.
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.
