INTRODUCTION 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.
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.
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.

ATTACHING THE CONSOLE 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 console connection supports a Digital Equipment Corporation VT200™ or VT300™ series terminal or PC emulation of one of these terminals.
ATTACHING THE CONSOLE Table 2-1.

ATTACHING THE CONSOLE 2.2 CONSOLE CABLE CONFIGURATION A single female DB-9 receptacle provides a Console interface to the management terminal. Depending on your 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.

GETTING STARTED CHAPTER 3 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.
GETTING STARTED • 3.2 The RETURN command menu selection takes you back to the previous screen. 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.

MRXI/LM 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.
GETTING STARTED When you enter the correct password, a MRXI SNMP Local Management Screen is displayed, indicating that MRXI/LM is ready for operation (see Figure 3-3). The menu command MAIN is highlighted. If an incorrect or invalid password is entered, the password prompt remains on the screen, allowing you to enter the correct password. 4. Press Return to display the Device/Port Information Screen (see Figure 3-4). The Device/Port Information Screen serves as the main screen for MRXI/LM.

GETTING STARTED 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.
GETTING STARTED 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). 7. Press Return. The Device/Port Information screen is displayed(Figure 3-4).

USING THE DEVICE/PORT INFORMATION SCREEN CHAPTER 4 USING THE DEVICE/PORT INFORMATION SCREEN This chapter describes local management commands, field entries and statistical information presented on the MRXI/LM Device/Port Information screen. The Device/Port Information screen, shown in Figure 4-1, summarizes HUB status and operational information related to the available Ethernet ports.
USING THE DEVICE/PORT INFORMATION SCREEN Device Information Device Name: - is a name, up to 20 characters in length, that you can assign and enter to serve as a meaningful identifier for the HUB. Set Modem Baud Rate: - allows changing the Console Port baud rate when using a modem. Ethernet Address: - displays the Ethernet address of the HUB in hex. Set IP Address: - displays the TCP/IP address currently assigned for the HUB. You can set this field according to your network requirements.
USING THE DEVICE/PORT INFORMATION SCREEN Receive Collisions: - indicates the number of receive collisions detected at the currently selected Ethernet port (Port n). Transmit Collisions: - indicates the number of transmit collisions detected at the currently selected Ethernet port (Port n). Port Media Type: - displays the type of media interface at the currently selected port.
USING THE DEVICE/PORT INFORMATION SCREEN NLNK (no link) - indicates that a link has not been established on the currently selected port. N/A (not applicable) - indicates that the currently selected port is not a 10Base-T Twisted Pair or Fiber Optic Link port. Command Menu Selections EXIT - ends the current local management session and displays the Password screen. SAVE - saves the information currently displayed on the Device/ Port Information Screen.
