Welcome to Cabletron Systems
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:
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.

INTRODUCTION
1.2 THE MRXI
The MRXI 10BASE-T HUB and MRXI-2 10BASE-T HUB are 10BASET 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.

INTRODUCTION
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
User Manuals,

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
console connection supports a Digital Equipment Corporation VT200™
or VT300™ series terminal or PC emulation of one of these terminals.

GETTING STARTED
This chapter explains the conventions used by this manual to describe
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,

• 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.

3.5 ACCESSING LOCAL MANAGEMENT VIA MODEM
Local management can be accessed through a Hayes, or Hayes
Compatible Modem meeting the AT Command Set. The modem is
attached to the 9 pin port labeled CONSOLE on the MRXI.
3.5.1 Cable Configuration
Local Management is accessed by an RS232 cable available from
Cabletron Systems. This cable connects the modem to the MRXI
Console port.
The pin out for a cable, and a 9 pin connector at the MRXI end of the
cable, should be configured as follows:
9 Pin Male Connector 25 Pin Female Connector
(MRXI end) (Modem end)
Pin 2 (Transmit) to Pin 2 (Transmit)
Pin 3 (Receive) to Pin 3 (Receive)
Pin 5 (Ground) to Pin 7 (Ground)
Pin 7 (Request to Send) to Pin 20 (Data Terminal Ready)
Pin 8 (Clear to Send) to Pin 8 (Data Carrier Detect)
3.5.2 Accessing Local Management
Before accessing Local Management using the modem, the MRXI baud
rate must be set to the rate of the modem. Using a terminal, set the
baud rate at the Device/Port Screen. The default setting is 9600. Refer
to Chapter 4
SCREEN
After verifying the baud rate proceed as follows:
1. Plug the 9 pin end of the cable into the port labeled CONSOLE on
the MRXI.
2. Plug the 25 pin end of the cable into the 25 pin RS232 port on the
modem.

3. Turn modem on. The modem must be set for Auto Answer and DCD
(Data Carrier Detect) active. Refer to the modem manual for
procedures.
4. Call the modem. The Password Screen is displayed when the
connection is established.
5. Enter the Password. Any Superuser password (assigned at the
Community Names Screen) is valid.
6. Press Return. The MRXI SNMP LOCAL MANAGEMENT screen is
displayed (Figure 3-3).
