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.
