INTRODUCTION
Welcome to the
Modules Installation Guide
93 Series Active Token Ring Media Interface
. This manual serves as a reference for installing and troubleshooting Cabletron Systems TRMIM-22A™, TRMIM-24A™, TRMIM-42A™, and TRMIM-44A™.
The TRMIM-22A, TRMIM-24A, TRMIM-42A, and TRMIM-44A comprise a family of
Active
Token Ring Concentrator modules. The TRMIM-22A and TRMIM-24A provide 12 and 24 active trunk coupling unit (TCU) ports, respectively, that support voice grade unshielded twisted pair (UTP) 100 ohm cabling. The TRMIM-42A and TRMIM-44A have 12 and 24 active TCU ports, respectively, supporting IBM® type 1, 2, 6, and 9 shielded twisted pair (STP) 150 ohm cabling.
Both UTP concentrator modules and both STP concentrator modules are equipped with RJ-45 modular connectors. The concentrator module RJ-45 connectors provide for connection of the cabling shield. All four concentrator modules are designed for installation in any Cabletron Systems Multi Media Access Center (MMAC™) equipped with a Flexible Network Bus (FNB™). All four concentrator modules are IEEE 802.5 compliant and compatible with IBM™ products.
Note:
The term
Concentrator Module
when describing features and functions that are common to the TRMIM­22A, TRMIM-24A, TRMIM-42A, and TRMIM-44A. The terms TRMIM-22A, TRMIM-24A, TRMIM-42A, and TRMIM-44A are used when it is necessary to describe features that are unique to any device.

INTRODUCTION
contents and to gain an understanding of the features of the 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 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 ACTIVE CONCENTRATOR MODULES
The TRMIM-22A, TRMIM-24A, TRMIM-42A, and TRMIM-44A, shown in Figure 1-1, can be installed as a free standing token ring network or to provide UTP or STP connectivity to an existing token ring network. All four 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 bounded by externally accessible Ring-In and Ring-Out ports.)
All four concentrator modules are designed for installation into a Cabletron Systems MMAC, where they can be used to create an independent 12 or 24 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.

INTRODUCTION
Features of the concentrator module include:
Number of Connections
• TRMIM-22A 12 - Unshielded RJ-45 ports
• TRMIM-42A 12 - Shielded RJ-45 ports
• TRMIM-24A 24 - Unshielded RJ-45 ports
• TRMIM-44A 24 - Shielded RJ-45 ports
Multiple concentrator modules can be installed into an MMAC to increase the number of UTP/STP ports available on a token ring network.
Distance and Cable Type

at 16 Mbit/s ring speed.
and
The UTP concentrator modules support voice grade Unshielded Twisted Pair (UTP), categories 3, 4 and 5 cabling. The STP concentrator modules support IBM type 1, 2, 6, and 9 STP cabling. Detailed specifications for supported cable types and lengths are listed in Chapter 2,
Cable Signal Polarity
Installation Requirements/Specifications.
Differential Manchester encoding is utilized for each of the concentrator module TCU ports. This permits passing data regardless of receive link polarity.
Note:
If a reversed polarity condition is discovered, the segment should be removed from the network and wired correctly (according to the connector wiring shown in
Specifications
Chapter 2, Installation Requirements /
). This will avoid the potential for future compatibility
problems.

Multiple Concentrator Modules
Several concentrator modules can be installed into a single MMAC and configured as independent rings or linked together into a single ring network thru the FNB. Configuration guidelines can be found in Chapter 3, Installing the Concentrator Module.
Multiple MMACs in a Ring Network
Several MMACs can be connected into the same ring network by installing token ring concentrators (TRMIM-10R/20R with externally accessible Ring-In/Ring-Out ports) or token ring repeaters (TRRMIM-A/2A/4A). The choice between using concentrators or repeaters depends on specific network configurations. Refer to Cabletron Systems
Installation Guide
or
TRRMIM-A/2A/4A Installation Guide
TRMIM-10R/20R
for more information on the use of these products or contact Cabletron Systems Technical Support.
A variety of network management tools can be used to control and monitor TRMIMs, including Cabletron Systems Local Management, Remote LANVIEW/Windows™, and SPECTRUM™.
Multi-Ring Out Capability
With this feature any port of the concentrator module may be set as a ring-out port through the MMAC management module. In this configuration a stand-alone passive concentrator (such as an IBM
8228) may be added to the ring as shown in Figure 1-2. This allows
