CHAPTER 1

INTRODUCTION

The

Twisted Pair Switching Media Interface Module (TPXMIM)

is a

switchable multi-channel Ethernet repeater that resides in a Multi Media

Access Center

(MMAC) hub. This manual explains how to:

• install the TPXMIM

• connect the module to an existing network

• troubleshoot any installation/operational problems.

In addition, Appendices contain TPXMIM and Ethernet Port Interface

Module (EPIM) environmental and operational speciﬁcations.

This manual serves as a simple installation and troubleshooting reference

guide for the TPXMIM. To gain a full understanding of this device and its

capabilities, and to help eliminate any potential problems during or after

installation, please be sure to read and understand all of the instructions

and information in this document and in the release notes.

1.1 USING THIS MANUAL

You should have a general working knowledge of Ethernet or IEEE 802.3

type data networks prior to installing the TPXMIM. The following

summarizes the organization of this manual.

Chapter 1,

Introduction

, discusses TPXMIM features, and provides an

overview of the device’s capabilities. This chapter concludes with a list of

related documentation and how to obtain additional support related to

TPXMIM installation and operation.

Chapter 2,

Speciﬁcations/Requirements

, provides speciﬁcations and

network requirements to consider before installing the TPXMIM.

CHAPTER 1:

INTRODUCTION

Page 2

TPXMIM Installation Guide

Chapter 3,

Installation/Conﬁguration

provides instructions/guidelines

on how to install the TPXMIM into an MMAC-FNB, set the board or

individual ports to a speciﬁc MMAC Channel, install/replace an optional

EPIM, and connect segments to your device using an optional EPIM.

Chapter 4,

Testing/Troubleshooting

, provides some testing procedures to

ensure the TPXMIM is working properly before installing it into your

network. This chapter also details the TPXMIM LANVIEW

LEDs that

enable you to quickly diagnose network/operational problems and

includes a troubleshooting checklist.

Appendix A,

Twisted Pair Wiring Tables

, provides the wiring tables to

assist in using a punchdown block to wire twisted pair segments.

Appendix B,

EPIM Speciﬁcations

, lists the speciﬁcations for each

optional EPIM available for the TPXMIM.

1.2 TPXMIM FEATURES

LANVIEW

Cabletron provides a visual diagnostic and status monitoring system,

called LANVIEW, with the TPXMIM. LANVIEW LEDs help you

quickly identify device, port, and physical layer problems.

“Switching”

The TPXMIM brings “bank switching” and individual “port assignment”

to the MMAC chassis. Using any multi-channel management module

(i.e., the EMME or EMM-E6), you can assign either the entire board

(bank switching) or each individual port (port assignment) to any of the

three Ethernet channels on the MMAC-FNB (i.e., Channel A, B, or C).

Connectivity

The TPXMIM series offers four connector versions:

• TPXMIM-20 — nine RJ45 ports; one EPIM port

• TPXMIM-22 — twenty-one RJ45 ports; one EPIM port

• TPXMIM-33 — one 50-pin Champ connector; one EPIM port

• TPXMIM-34 — two 50-pin Champ connectors; one EPIM port

OVERVIEW

TPXMIM Installation Guide

Page 3

MIB Navigation

Assigning the TPXMIM board or individual ports to speciﬁc Ethernet

channels, or obtaining TPXMIM board or port statistics, requires a multi-

channel management device (e.g., EMME or EMM-E6) and access to a

MIB walking tool. The EMME or EMM-E6 allows MIB access both

locally (i.e., Local Management) and remotely (i.e., additional Cabletron

Remote Management packages).

For information on how to use the Local Management MIB walking tool,

refer to either the EMME or EMM-E6 Local Management manual. For

information on how to use a Remote Management MIB walking tool,

refer to documentation speciﬁc to that Remote Management package.

Compliance

Each TPXMIM utilizes Repeater Interface Controller (RIC) technology.

RIC technology integrates all repeater functionality into one integrated

circuit. This makes the TPXMIM fully 10Base-T IEEE 802.3i compliant.

Fault Tolerance

By performing its own repeater functions, the TPXMIM greatly enhances

the fault tolerance of the MMAC. By not relying on one central module to

perform repeater functions, TPXMIMs eliminate a single point of failure.

In addition, the TPXMIM provides port segment partitioning and

reconnection. This feature assures that problem segments do not affect

any other segments. If the TPXMIM detects 31 consecutive collisions on

any segment, or if a collision detector remains on for more than 110

the TPXMIM automatically partitions that segment. When the TPXMIM

receives a good packet from the segment, it automatically reconnects.

1.3 OVERVIEW

The

Twisted Pair Switching Media Interface Module

(TPXMIM)

provides board or individual port connectivity to any MMAC-FNB

Ethernet Channel (i.e., Channels A, B, or C). All ports initially default to

Channel B upon power up and require a Management Information Base

(MIB) change to access any other channel. Refer to Chapter 3,

Installation/Conﬁguration

, for additional information on how to assign

the TPXMIM board or individual ports to speciﬁc channels.
