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.
