TPIM Speciﬁcations

A.1 Overview

Token Ring Port Interface Modules (TPIMs) are media adapter cards which extend network connections onto a variety of media. When installed into Ring In and Ring Out ports, TPIMs support the expansion of a Token Ring from the host module into other devices. Each TPIM has a different type of cable port to support a different media connection. Table A-1 lists each available Cabletron Systems TPIM and its respective connector.

Table A-1. TPIMs and their Corresponding Media

TPIM	Media Type	Connector


TPIM-T1	Shielded Twisted Pair	DB9

TPIM-T2	Unshielded Twisted Pair	RJ45

TPIM-T4	Shielded Twisted Pair	RJ45

TPIM-F2	Multimode Fiber Optic	ST

TPIM-F3	Single mode Fiber Optic	ST

The LNK (Link) LED on the face of each TPIM indicates the following:

•Green - Inserting.

•Red (TPIM-T1/T2/T4 only) - No Link (Autowrapped)

•Off - No Link (Wrapped or Disabled)

All Cabletron TPIMs are interchangeable and hot-swappable.

A.2 Twisted Pair TPIM Pinouts

Each TPIM that supports Twisted Pair cabling has two operating modes: Ring In / Ring Out and Station. For use with STHI, the TPIM is switched to operate in Ring In/ Ring Out mode. The pinouts for TPIMs in station applications are different from pinouts for Ring In / Ring Out applications. Illustrations of the Ring In / Ring Out pinouts follow.
