INTRODUCTION
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.
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
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.
1.2THE 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

INTRODUCTION
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-22A12 - Unshielded RJ-45 ports
•TRMIM-42A12 - Shielded RJ-45 ports
•TRMIM-24A24 - Unshielded RJ-45 ports
•TRMIM-44A24 - 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

STP lobe cable lengths up to
TCU ports regenerate, reshape and filter the incoming

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.

INTRODUCTION
Speed Fault Protection
If a station attempts to inserting into the ring at a ring speed (4 or 16
mbits) different from what is set on the TRMIM, that port is
automatically bypassed to prevent the ring from beaconing. The
PEN
LED flashes indicating the port with the speed fault is
bypassed.
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

for a star-wired network with the MMAC at the center. Consult the
Token Ring Local Management for the TRMM, and TRMBM-S
manual for information on configuring this port.

LANVIEW LEDs
Several LEDs, on the front panel of the concentrator module, are
used to indicate the ring speed, presence of a hardware error,
status, and management statistics for each of the TCU ports.
LANVIEW is an effective tool to help you quickly diagnose your
physical layer network problems.
