CHAPTER 1
INTRODUCTION
Welcome to the TRMM ™ /TRMMIM ™ Token Ring Management
Modules Installation Guide
. This manual describes module capabilities,
specifications, and setup and installation instructions. It is intended for all
users of the TRMM and TRMMIM.
The Token Ring Management Module (TRMM™) and Token Ring
Management Media Interface Module (TRMMIM™) are designed for use
in Cabletron’s Multi Media Access Center (MMAC™) models,
MMAC-M3FNB, MMAC-M5FNB, MMAC-M8FNB. The modules are
802.5 compliant, IBM compatible, and support Simple Network
Management Protocol (SNMP) management. They also provide Local
Management application tools, which can be accessed via management
terminal, modem, or Telnet connection.
1.1 USING THIS MANUAL
Please read this manual to gain an understanding of product features prior
to installing and operating the TRMM and TRMMIM. Having a working
knowledge of Token Ring (IEEE 802.5) networks will prove helpful
during the installation.
The manual is organized into the following chapters:
Chapter 1,
Introduction , describes the manuals structure and module
features and capabilities. It also lists product reference, help, and support
sources.
Chapter 2,
Installation Requirements and Specifications , describes
module and peripheral device operational requirements and specifications.
Chapter 3,
Module Configuration and Installation , describes
configuration, installation, and cabling procedures for the modules and
peripheral devices.

Chapter 4, Testing and Troubleshooting , describes checks to perform if
operational problems are encountered after installation. It also describes
LANVIEWLEDs,CabletronSystemsbuilt-in,visualdiagnosticandstatus
monitoring system, and POWER UP DIAGNOSTIC tests.
1.2 TRMM AND TRMMIM OVERVIEW
The TRMM and TRMMIM (Figure 1-1) can be used together for
managing and monitoring multiple Token Rings in the same MMAC hub.
Both modules are controlled by Intel’s™ i960 CPU running at 24 MHz.

Both are also functionally identical, providing:
• Token Ring support on the MMAC Flexible Network Bus (FNB)
• Selectable Token Ring speeds of 4Mbps and 16Mbps
• In-band (SNMP) and out-of-band (RS232) management
• Flash EPROM firmware enhancements via Trivial File Transfer
Protocol (TFTP)
• LANVIEW LED monitoring and diagnostics system
• Data and system configuration (Non-Volatile Random Access
Memory, NVRAM) protection
NOTE: Although some earlier version modules’ COM ports are labeled
Modem and Console respectively, they also provide the same functionality
as modules with COM ports labeled COM 1 and COM 2
.
1.2.1 Module Configuration in the MMAC
The TRMM provides management for single or interconnected Token
Ring networks via the backplane from the MMAC
right-most
management slot (lower-most on the MMAC-3) . When used in
conjunction with the TRMM (or also, for example, when use with a
EMME), the TRMMIM provides the same management functions as the
TRMM for all boards inserted to its left from any MMAC
Media
Interface Module (MIM) slot
.
TheTRMM and TRMMIM can also be used with other Cabletron modules
to support a range of Token Ring and mixed Token Ring and Ethernet
configurations in the same MMAC hub. Contact Cabletron’s Networking
Services Department for information on configuration options.

INTRODUCTION
1-4
1.2.2 Management Access
Local Management (LM) is a firmware image embedded in both the
TRMM and TRMMIM that provides a management application interface
for monitoring and managing the modules. Access to Local Management
isprovided by the RS232 COM 2, or Console, communication port located
on the front panel of each module and via in-band Telnet connection.
COM 2 port
The COM 2 port supports out-of-band LM access via a management
terminal and modem connections (see Section 3.4 for terminal and modem
connection procedures).
NOTE: Remote Management access to the SNMP compliant TRMM and
TRMMIMis providedby theremote networkmanagementtools,Cabletron
Systems’ Remote LANVIEW/Windows and SPECTRUM.
1.2.3 Testing and Troubleshooting Systems
LANVIEW LEDs, located on each module’s front panel, provide an
at-a-glance means of monitoring the operational status of a module. LEDs
indicate whether a module is operating correctly, the ring speed, and
whether a module is actively managing other modules in the MMAC.
POWER UP DIAGNOSTIC test results appears on your management
terminal screen whenever the modules are powered on or reset. The tests
provideadditional system-level informationaboutthe operational statusof
a module. Your terminal must be connected to the COM 2 port to view the
tests. See Chapter 4,
Testing and Troubleshooting , for more information
about monitoring systems.
1.2.4 System Safeguards
The TRMM and TRMMIM both support UPS device monitoring (from
LANVIEW or SPECTRUM) via connection to the COM 1 port. The UPS
device provides a regulated and constant power source in the event of
power-supply faults. Contact your Cabletron Sales Representative to order
the necessary port connectors.

The modules are also equipped with a back-up battery that provides power
to Non-Volatile Random Access Memory (NVRAM), preserving crucial
system level data and configuration settings. Thermal sensors included in
both modules set off an alarm warning of overheating before the
temperature becomes critical.

CHAPTER 2
INSTALLATION REQUIREMENTS AND
SPECIFICATIONS
Before installing either module, review the requirements and operating
specifications outlined in this chapter. It describes network requirements
for the TRMM and TRMMIM and also setup requirements for a
management terminal and a modem. Failure to follow these guidelines
could result in poor network performance.
2.1 MMAC REQUIREMENTS
Both the TRMM and TRMMIM must be installed in an MMAC
(MMAC-3FNB, MMAC-5, or MMAC-8FNB) equipped with a flexible
Network Bus (FNB). No link exists between the module and other token
ring boards in the MMAC without the FNB.
N OTE : The FNB is a full-height, full-width backplane that links
Cabletron Systems token ring products. MMAC-3s and MMAC-8s
(without an FNB) can be upgraded with an FNB to provide greater
flexibility to the network. Contact Cabletron Systems Technical Support
for more information.
A Power Supply Module (PSM) is required in the MMAC’s power supply
slot when installing the TRMM or TRMMIM in an MMAC without an
internal power source. One PSM is required for every two Management
Modules.
2.1.1 Terminal Setup Requirements
The COM 2, or Console, port supports a Digital Equipment Corporation
VT200™ or VT300™ series terminal or a PC emulation of one of these
terminals. The maximum console cable length is 50 feet.
Table 2-1 lists setup requirements for the Local Management terminal. On
VT200 or VT300 series terminal, press
F3 to access the Setup Directory.
