The 9E106-06 Ethernet Switching Module provides one port per channel for Cabletron Systems EPIMs. EPIMs allow connecting to the 9E106-06 using different media types. Cabletron Systems offers a variety of EPIMs whose specifications are explained in the following sections.
Verify that the EPIM is the proper revision before installing it. See Installing the EPIM on page 2-4 for details.
EPIM-T
The EPIM-T is an RJ-45 connector supporting UTP cabling. It has an internal Cabletron Systems TPT-T™ 10BASE-T Twisted Pair Transceiver.
The slide switch on the EPIM-T 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-1shows the pinouts for the EPIM-T in both crossover positions.
The link distance is up to 100 meters on unshielded twisted pair cable as specified by ANSI TP-PMD.
