EPIMs

The 9E132-15 MicroLAN Switch Extension Module provides one port per channel

for Cabletron Systems EPIMs. EPIMs allow connecting to the 9E132-15 using

different media types. Cabletron Systems offers a variety of EPIMs whose

speciﬁcations are explained in the following sections.

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-1 shows 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.

Verify that the EPIM is the proper revision before installing. See Installing the

EPIM on page 2-4. for details.
