CHAPTER 1
INTRODUCTION
Welcome to Cabletron Systems MRXI/LM Local Management for
the Cabletron Systems MRXI 10BASE-T HUB User's Manual.
This manual serves as a simple reference guide for using MRXI/LM™,
providing information to help you configure the MRXI™ and MRXI-2
and, if necessary, diagnose problems with your network.
NOTE: This manual covers both the MRXI and MRXI-2. The two units
are functionally identical. The MRXI provides connections for ports 1
through 12 via a 50 pin Champ connector, while the MRXI-2 provides
twelve RJ-45 connectors. Throughout this manual the term MRXI is
used to cover both units unless otherwise specified.
1.1 USING THIS MANUAL
Read through this manual to become familiar with its contents and to
gain an understanding of the features and capabilities of MRXI/LM. A
general working knowledge of Ethernet networks and the IEEE 802.3
standard is necessary for interpreting and using MRXI/LM.
Chapter 1, Introduction, outlines the contents of this manual, briefly
describes features and functions performed by the Hub and MRXI/LM,
and concludes with a list of related manuals.
Chapter 2, Attaching the Console , describes terminal
characteristics, connecting console cabling, and configuring the
management console.
Chapter 3, Getting Started, describes the initial steps required to
access MRXI/LM. It describes each of the screens and the available
commands.
Chapter4, Using the Device/Board/Port Counters Screen ,
describes the status and statistics information available for the MRXI.
Chapter 5, Using Community Names , describes entering and using
a community names table.
Chapter 6, MRXI/LM Messages , explains messages that can appear
at the top of the MRXI/LM terminal display.

INTRODUCTION
Page 1-2
1.2 THE MRXI
The MRXI 10BASE-T HUB and MRXI-2 10BASE-T HUB are 10BASE-
T and 802.3 compliant repeaters that allows expansion of existing
802.3 networks using a variety of media. The two hubs are identical
except for the physical connections for ports 1 through 12. The MRXI is
equipped with a 50 pin Champ connector, while the MRXI-2 provides
twelve RJ-45 connectors. The MRXI supports out-of-band and in-band
Simple Network Management Protocol (SNMP) compliant network
management. Out-of-band management for the MRXI is provided by
MRXI/LM. The MRXI is supported by several in-band network
management tools including: Cabletron Systems Remote LANVIEW/
Windows™, and SPECTRUM™.
1.3 THE MRXI/LM
The MRXI/LM is a menu driven, integrated network management tool
that permits management and control of the MRXI. MRXI/LM can be
used to:
• Display current MRXI status and statistics for the MRXI
network ports
• Define community names and access privileges
• Diagnose network problems.
The MRXI is an SNMP compliant device that permits setting
community names for your MRXI. The Community Names feature
serves two purposes:
• As a security feature that defines access privileges for SNMP
requests from SNMP management stations
• Community names let you to designate the network
management workstations that will receive alarms from the
MRXI.
You can access MRXI/LM through a management terminal connected
to the 9-pin Console port on the rear panel of the MRXI. The console
port supports a Digital Equipment Corporation, VT200™ or VT300™
series terminals or PC emulation of the VT200 or VT300 terminals.

1.4 REMOTE LANVIEW/WINDOWS
MRXI/LM provides the foundation for Remote LANVIEW/Windows,
Cabletron Systems Remote Network Control Management Software
package (This package can be purchased separately from Cabletron
Systems.). Remote LANVIEW/Windows allows you to control and
manage multiple MRXIs from a single Ethernet workstation. With
Remote LANVIEW/Windows, you can view statistics for your MRXI,
both numerically and graphically, using dynamic bar and pie charts
and performance graphs. You can also enable a statistics logging and
reporting function that will log MRXI statistics to a report file for
future reference.
For more information on using Remote LANVIEW/Windows with the
MRXI, consult the Cabletron Systems Remote LANVIEW/Windows
User Manuals , or call Cabletron Systems at [phone].

CHAPTER 2
ATTACHING THE CONSOLE
This chapter describes information on the characteristics of supported
terminals, configuring the management console and connecting the
console cabling.
2.1 LOCAL MANAGEMENT CONSOLE
MRXI/LM is accessed by attaching a management console at the DB-9
CONSOLE port on the rear panel of the MRXI (see Figure 2-1). The
consoleconnectionsupportsaDigitalEquipmentCorporationVT200™
or VT300™ series terminal or PC emulation of one of these terminals.
Figure 2-1. Management Console Connection
Table 2-1 lists the setup requirements for the local management
console. If your terminal is a Digital Equipment Corporation VT200™
or VT300™ series terminal, press
F3 to access the Setup Directory. If
you have a terminal emulation of the Digital Equipment terminals,
refer to your equipment user manual for setup procedures.

2.2 CONSOLE CABLE CONFIGURATION
A single female DB-9 receptacle provides a Console interface to the
managementterminal. Depending onyour specific terminal,one of two
cable configurations (9 pin to 25 pin or 9 pin to 9 pin) is used for the
connection to the MRXI Console port. Figure 2-2 shows the pinout for
both cables.
Figure 2-2. Console Cable Pinouts
Connect the console to the MRXI as follows:
1. Attach the male 9-pin connector to the CONSOLE port on the rear
of the MRXI.
2. Attachthe female end (25-pin or9-pin, as applicable) to theCOMM
port on the terminal.

each of the screens and commands available with MRXI/LM. It also
describes using the keyboard and the initial steps required to access
MRXI/LM.
3.1 USING THE MANAGEMENT KEYBOARD
The MRXI/LM screens are arranged with pertinent network
information filling much of the display area and several menu
selections across the bottom. To select a menu option or alter a field,
use the keyboard arrows (up, down, left, and right) to highlight the
desired item. Only fields that can be changed can be highlighted.
Incorrect entries (field value exceeded, etc.) are blocked and result in
an appropriate error message (refer to Chapter 6,
MRXI/LM
Messages ).
To make a menu selection:
1. Highlight the menu selection
2. Press Return
To alter a field:
1. Highlight the desired field
2. Enter the new information
3. Press Return
To toggle a field (select the alternative selection for a field):
1. Highlight the desired field
2. Press Return
• The TAB key performs the same function as the right arrow.
• Backspace permits correction of entries.

GETTING STARTED
Page 3-2
• The RETURN command menu selection takes you back to the
previous screen.
3.2 UNDERSTANDING THE SCREENS AND COMMANDS
The hub and local management are controlled by entering parameters
directly into the fields presented on the terminal display and by
selecting commands from menus presented at the bottom of each
display screen. The information in this manual covers all of the
available display screens and is presented using the following format
conventions:
• Screen formats are illustrated and each field is described
within the text.
a. Field titles for fields that can be altered via the terminal
keyboard are shown underlined.
b. When a default value exists for an entry, the default value
appears in italics in the screen illustration and the default
also appears in parentheses and italics within the text
description of the field.
• COMMANDS appear in UPPER CASE in the screen
illustrations and in the text.
3.3 MRXI/LM SCREENS
The MRXI/LM provides interactive screens that let you alter
information and select MRXI/LM functions from a series of
management screens. Figure 3-1 shows the paths between screens.

3.4 ACCESSING LOCAL MANAGEMENT VIA TERMINAL
To use MRXI/LM, the console must be connected as described in
Chapter 2, Attaching the Console . To access MRXI/LM:
1. If not already powered on, power on the MRXI.
2. Turn on power to the terminal. After a brief (approximately 5
seconds) warmup, the Password Screen appears (see Figure 3-2).
3. If you are not using the password feature of MRXI/LM or if you
have not yet applied your own password, press Return.
If you have applied a password known only to you, enter that
password now, then press Return.
