Cabletron Systems TRXI-22, TRXI-42 Connecting a Twisted Pair Segment to the TPIM-T2 or TPIM-T4

INSTALLATION

3.8.4Connecting a Twisted Pair Segment to the TPIM-T2 or TPIM-T4

The TPIM-T2 supports UTP cabling and the TPIM-T4 supports STP cabling. The method for connecting an RJ45 connector to an RJ45 port is the same for both UTP and STP cabling. Before connecting a segment to the TPIM-T2 /T4, check each end of the segment to ensure the wires are pinned properly. To connect a segment to a TPIM-T2/T4:

1.Insert the RJ45 connector on the twisted pair segment into the RJ45 port on the TPIM as shown in Figure 3-14.
