EPIM Speciﬁcations

Introduction

The 9C300-1 Environmental Module provides a port for Cabletron Systems EPIMs. EPIMs let you connect to the main network 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.

Position X (crossed over)

1. RX+	5. NC
2. RX-	6. TX-
3. TX+	7. NC
4. NC	8. NC

Position = (not crossed over)

1. TX+	5.	NC
2. TX-	6.	RX-
3. RX+	7. NC
4. NC	8. NC
