INTRODUCTION
INTRODUCTION
Welcome to the
Modules Installation Guide
TRFMIM Token Ring Fiber Media Interface
. This manual serves as a reference for
installing and troubleshooting Cabletron Systems TRFMIM-22™,
TRFMIM-26™, and TRFMIM-28™.
The TRFMIM is a fiber optic token ring concentrator module for use
in the Cabletron MMACs. These concentrators are designed in
compliance with the IEEE 802.5J token ring fiber optic standard.
Available with six, twelve or eighteen ports, the TRFMIM provides
connectivity over multimode fiber optic cable.
Note:
The term
Concentrator Module
is used throughout this manual
when describing features and functions that are common to the
TRFMIM-22, TRFMIM-26, and TRFMIM-28. The terms TRFMIM-22,
TRFMIM-26, and TRFMIM-28 are used when it is necessary to describe
features that are unique to any device.
1.1 USING THIS MANUAL
Prior to installing and operating your concentrator module, read
through this manual completely to familiarize yourself with its
contents and to gain an understanding of the features of the
concentrator module.
A general working knowledge of Token Ring (IEEE 802.5) networks
will be helpful when installing your concentrator module.
Chapter 1,
Introduction
, describes how to use this document,
provides an overview of the features and capabilities of each
concentrator module, and concludes with a list of related manuals.
Chapter 2,
Installation Requirements/Specifications
, lists the
network requirements that must be met before you begin installing
1-1
INTRODUCTION
your concentrator module. Detailed specifications for each of the
concentrator modules is also provided.
Chapter 3,
Installing the Concentrator Module
, contains
instructions for installing a concentrator module into the MMAC,
and attaching token ring station cabling.
Chapter 4,
Testing and Troubleshooting
, describes checks that you
can perform if you encounter problems after installing a
concentrator module. Instructions for using LANVIEW®,
Cabletron Systems built-in visual diagnostic and status monitoring
system, are also included.
1.2 THE TRFMIM CONCENTRATOR MODULES
The TRFMIM-22, TRFMIM-26, and TRFMIM-28, shown in
Figure 1-1, can be installed as a free-standing token ring network or
to provide fiber optic connectivity to an existing token ring
network. The concentrator modules are designed for installation
into a Cabletron Systems MMAC. Since they do not have externally
accessible Ring-In and Ring-Out ports, they are considered
concentrator modules
. (A concentrator in token ring applications is
defined as a device with multiple TCU ports bound by externally
accessible Ring-In and Ring-Out ports.)
All concentrator modules are designed for installation into a
Cabletron Systems MMAC, where they can be used to create an
independent 6, 12, or 18 port ring or to expand an existing token
ring network. When any concentrator module is used within an
MMAC, the concentrator module is connected via the Flexible
Network Bus (FNB) to other token ring MIMs, repeaters, or bridges.
