INSTALLATION REQUIREMENTS/SPECIFICATIONS

2.3EPIM SPECIFICATIONS

EPIMs let you connect the SEH to the main network using different media types. Cabletron Systems offers a variety of EPIMs. The following sections explain specifications for each EPIM.

2.3.1EPIM-T

The EPIM-T is an RJ45 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 cross-over 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 2-3 shows the pinouts for the EPIM-T in both cross-over positions.
