Page 7: Introduction
CHAPTER 2: Introduction 2. Introduction The Ethernet to Token Ring Bridge is a two-port bridge that provides connectivity between devices on a token-ring LAN (local area network) and an Ethernet LAN. (See Figure 2-1.) All bridges are controlled by the Bridge Manager, a software program that runs on a PC on the token-ring LAN. -

• The Ethernet to Token Ring Bridge, • This manual, • (1) AC power cord, • (1) Pack of four rubber stick-on feet, and • (1) Software download diskette. If any of these items are missing or damaged, call Black Box. -
Page 9: Installation
CHAPTER 3: Installation 3. Installation Before installing any bridge, the network should be fully planned. For information on network planning, you may want to read the IBM Token-Ring Network Introduction and Planning Guide (GA27-3677-01). The NetScan feature of the Bridge Manager software simplifies the installation process because it allows you to install an unconfigured bridge, and to configure it through the token-ring network using the Bridge Manager. -
Page 10: Setting The Lan Speed
ETHERNET TO TOKEN RING BRIDGE 3.2 Setting the LAN Speed The token-ring LAN connected to the Ethernet to Token Ring Bridge can operate at 4 or 16 Mbps. The LAN speed can be changed either by using the Bridge Manager program or by switching a jumper on the main circuit board inside the Ethernet to Token Ring Bridge. -
Page 11: Installing The Bridge
CHAPTER 3: Installation 3.3 Installing the Bridge 1. Make sure the LAN speed has been set correctly; see Section 3.2. 2. Install the bridge in a rack, or attach the rubber feet and set it on a table. 3. Make the Ethernet connection by attaching a transceiver, or the male end of a transceiver cable, to the Ethernet port on the front of the bridge. -

Page 13: Configuration
CHAPTER 4: Configuration 4. Configuration Control of a bridge using the Bridge Manager program is covered in detail in the Bridge Manager manual. This chapter explains Bridge Manager screens and functions specific to the Ethernet to Token Ring Bridge. When a new bridge is first turned on, it will communicate over the token ring LAN with the Bridge Manager program. -
Page 14: Mac Addresses
ETHERNET TO TOKEN RING BRIDGE 4.2 MAC Addresses The procedure for converting MAC addresses is as follows: 1. Separate the 12-digit (Ethernet or token ring) MAC address into six pairs. For example: 10 00 5A 4D BC 2. Using the table below, convert the first pair. In this example, 10 translates to 08. 3. -
Page 15: Ethernet Statistics
CHAPTER 4: Configuration 4.3 Ethernet Statistics In addition to token-ring statistics (covered in the Bridge Manager manual), the Bridge Manager allows for monitoring of the Ethernet statistics shown below. To access the LAN Status screen, select Window 3. 3.Lan Status ETHERNET TRANSMISSION ERROR COUNTS Lost carrier sense error count . -
Page 16: Operation
ETHERNET TO TOKEN RING BRIDGE 5. Operation 5.1 Operating Modes An Ethernet to Token Ring Bridge has two operating modes: startup and bridge mode. A bridge’s operating mode can be changed by issuing a command from the Bridge Manager. See the Bridge Manager manual for more information. -
Page 17: Lcd Displays
CHAPTER 5: Operation 5.3 LCD Displays The LCD (liquid crystal display) on the bridge’s front panel displays various types of information. When the bridge is first powered on, it initializes itself, and various system status messages are displayed. If the bridge passes all self-tests and comes up successfully, a message identifying the bridge will be displayed. An example is given below. - Page 18 ETHERNET TO TOKEN RING BRIDGE VERSION LLC nnnn This message displays the current LLC code version level. VERSION HDW nnnn This message is the hardware revision level when the bridge was manufactured. If a bridge has received a factory hardware upgrade, however, the version number displayed here will not be accurate. When in doubt, check the label on the bottom of the bridge housing.

CHAPTER 5: Operation 5.5 Detailed Hardware Diagnostics Use the Bridge’s LCD panel when troubleshooting. To run detailed hardware diagnostics, turn the Bridge OFF. Press and hold the Status toggle switch in the DOWN position and turn the Bridge back ON. The bridge will go through a series of detailed self-tests. - Page 22 ETHERNET TO TOKEN RING BRIDGE To connect a PC to a Ethernet to Token Ring Bridge control port: 1. Connect a straight-through RS-232 cable between the PC’s COM1 port and the bridge’s control port. If you are using modems, set the bridge-side modem to auto-answer (and you will need RS-232 crossover cables).

APPENDIX B: Ethernet to Token Ring Bridge MIB Appendix B: Ethernet to Token Ring Bridge MIB The Ethernet to Token Ring Bridge SNMP agent supports the following Management Information Bases (MIBs): • RFC1286 • RFC1213 B.1 The brSnmpConfigParam Group This group contains variables needed to configure the SNMP agent. New values set to variables in this group will take effect only after a bridge restart (see the Bridge Manager manual). -
Page 26: The Broperationalparam Group
ETHERNET TO TOKEN RING BRIDGE B.3 The brOperationalParam Group Most of the variables in this group have a counterpart variable in either the RFC1286’s dot1dSr or the brBridgeAdditionalParam group. The values of the variables in this group may be different from those of their counterparts in the other two groups because variables in the other two groups can be set to different values any moment.
