APPENDIX A
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.
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.
