BRIDGE/ROUTER

This guide contains the information you need to install and configure your OfficeConnect® NETBuilder® 10 bridge/router.

The basic configuration that you will establish is shown in Figure 1. This configuration supports a leased-line connection between two OfficeConnect bridge/routers. It also supplies an ISDN dial-on-demand backup line.

As you are configuring your router, you will be asked to make choices based on what is required on your network.

6 CONFIGURING YOUR OFFICECONNECT NETBUILDER 10 BRIDGE/ROUTER

The instructions in this guide describe how to configure Office A. After you’ve completed the configuration for Office A, the same configuration steps need to be performed at Office B.

This guide has the following sections:

Prerequisites

Preconfiguration Set Up (which includes installing the OfficeConnect hardware)

Configuration Procedure

Prerequisites

Before you begin installing and configuring your OfficeConnect bridge/router, you must satisfy the following prerequisites:

You must have a PC on your network that will function as your network management station (NMS).

This NMS must have browser software that is compatible with Web Link: either Netscape Navigator 4.08 or later, or Microsoft Internet Explorer 4.01 or later.

Web Link is the web-based network management application that comes with your OfficeConnect NETBuilder bridge/router.

You need to obtain IP addresses and subnet masks for your network.

You will also need to order a leased line and an ISDN line from your telco provider or providers.

When your ISDN line is installed you will receive information regarding the ISDN dial numbers, ISDN switch type, and SPID numbers. Retain this information for use during configuration.

Preconfiguration Set Up

7

Preconfiguration Set Up

This section describes the things you need to do before performing the actual network configuration.

Set Up the NMS as a DHCP Client

Refer to the documentation that came with your PC operating system for information on how to perform this set up.

Install the OfficeConnect on a Tabletop

Attach the plastic feet supplied with your OfficeConnect bridge/router; see Figure 2.

CAUTION: Do not restrict air flow around the sides and back of the bridge/router.

Figure 2 Attaching Plastic Feet to OfficeConnect

Bridge/Router

Remove feet from their adhesive backing.

Attach feet to the bottom of the chassis, using the semi-circle marks for placement.

Cable the Bridge/Router

Figure 3 shows the back panel connectors on the OfficeConnect bridge/routers. Refer to this figure when you attach or plug in cables.

Cable the Ethernet Connector

The OfficeConnect bridge/router accepts either a 10BASE-2 coaxial or 10BASE-T twisted pair (TP) Ethernet cable connection.

Attach a coaxial Ethernet cable to the BNC connector using a T-connector, or plug the 8-foot twisted pair cable supplied with the OfficeConnect bridge/router into the slot labeled TP.

Only one Ethernet connection is allowed.

Cable the Serial Port

Attach the special 3Com Flex-WAN cable to the port labeled Serial.

Attach the Flex-WAN end of the cable to the OfficeConnect bridge/router port. The other end of the cable has the appropriate connector (V.35, X.21, or RS-232) for a serial modem or CSU/DSU device.

You should have ordered the Flex-WAN cable when you ordered your OfficeConnect bridge/router. You can order a Flex-WAN cable from your local 3Com sales representative.

Plug the CSU/DSU or modem cable into the connector on the Flex-WAN cable. Connect the CSU/DSU or modem to the leased line provided by your telco vendor.

Preconfiguration Set Up

9

No leased line configuration is required. The OfficeConnect NETBuilder 10 bridge/router automatically configures the PPP connection when power to the bridge/router is turned on.

Cable the ISDN Port

Plug the 8-foot RJ-45 cable supplied with the OfficeConnect bridge/router into the port labeled WAN.

ISDN connections to an OfficeConnect bridge/router used in the U.S. and Canada also require a network termination (NT1) device and power supply. These can be leased from the telephone company or purchased from an ISDN equipment vendor. In other countries, you do not need to provide this equipment because the function of the equipment is provided by the ISDN equipment at your site.

Turn on Power to the OfficeConnect

Attach the power cord to the power receptacle on the back panel. This receptacle is labeled with the electrical rating for the power adapter included with your OfficeConnect bridge/router.

The OfficeConnect bridge/router does not have a power switch.

To turn power on, plug the other end of the power cord into an electrical outlet.

CAUTION: Make certain you plug the OfficeConnect bridge/router into an easily accessible electrical outlet located near the unit.

Wait for all the LEDs to turn green. When the LEDs are green you are ready to continue.

To turn off power or to reset the bridge/router, unplug the power cord from the outlet.

Restart the NMS DHCP Client

When you restart the PC, the NMS DHCP client (your PC) acquires an IP address from the OfficeConnect bridge/router DHCP server, which is enabled by default.

10 CONFIGURING YOUR OFFICECONNECT NETBUILDER 10 BRIDGE/ROUTER

This step is necessary to establish the connection between your NMS and the OfficeConnect bridge/router.

You are now ready to begin configuring your network.

Launch Web Link

Web Link is a built in web-based management tool that you can use to configure your OfficeConnect NETBuilder 10 bridge/router.

1Point the browser at the default IP address, 10.1.0.1.

2Log on using the user name Root with no password. The Web Link home page opens in the browser window.
