This guide contains the information you need to install and

conﬁgure your OfﬁceConnect

NETBuilder

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.

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.

OC10.book Page 6 Thursday, May 13, 1999 2:33 PM

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 3 shows the back panel connectors on the

OfﬁceConnect bridge/routers. Refer to this ﬁgure when you

attach or plug in cables.

Remove feet from their adhesive backing.

Attach feet to the bottom of the chassis,

using the semi-circle marks for placement.

OfﬁceConnect Back Panel Connectors

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

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.
