Connecting through a Telnet session

Features of the Netopia 4541/4542 can be conﬁgured through the console screens. Before you can access the console screens through Telnet, you must have:

■ A network connection locally to the router or IP access to the router.

Note: Alternatively, you can have a direct serial console cable connection using the provided console cable for your platform (PC or Macintosh) and the Console port on the back of the router. For more information on attaching the console cable, see “Connecting a console cable to your router” on page 5-3.

■ Telnet software installed on the computer you will use to conﬁgure the router

Console-Based Management 5-3

Conﬁguring Telnet software

If you are conﬁguring your router using a Telnet session, your computer must be running a Telnet software program.

■ If you connect a PC with Microsoft Windows, you can use a Windows Telnet application or simply run Telnet

from the Start menu.

■ If you connect a Macintosh computer, you can use the NCSA Telnet program supplied on the Netopia

4541/4542 CD. You install NCSA Telnet by simply dragging the application from the CD to your hard disk.

Connecting a console cable to your router

You can perform all of the system conﬁguration activities for your Netopia 4541/4542 through a local serial console connection using terminal emulation software, such as HyperTerminal provided with Windows 95, 98, 2000, or NT on the PC, or ZTerm, included on the Netopia CD, for Macintosh computers.

The Netopia 4541/4542 back panel has a connector labeled “Console” for attaching the Router to either a PC or Macintosh computer via the serial port on the computer. (On a Macintosh computer, the serial port is called the Modem port or Printer port.) This connection lets you use the computer to conﬁgure and monitor the Netopia 4541/4542 via the console screens.

DSL

10/100 Ethernet

Console Power

Console connection port DB-9 (male)

To connect the Netopia 4541/4542 to your computer for serial console communication, use a console cable appropriate to your platform:

■ A DB-9 connector end attaches to a PC.

■ A mini-DIN8 connector end attaches to a Macintosh computer depending on your computer’s serial bus

type. Since Macintosh computers have different serial bus connectors, you will need a mini-DIN8-to-DB-9 adapter. These are available from a variety of third-party manufacturers.

■ A DB-9 end of the Console cable attaches to the Netopia 4541/4542’s Console port.

■ If you connect a PC with Microsoft Windows 95, 98, 2000, or NT, you can use the HyperTerminal

application bundled with the operating system.

■ If you connect a Macintosh computer, you can use the ZTerm terminal emulation program on the supplied

Netopia 4541/4542 CD.

This chapter describes how to use the Easy Setup console screens on your Netopia 4541/4542. After completing the Easy Setup console screens, your router will be ready to connect to the Internet or another remote site.

Easy Setup console screens

Using four Easy Setup console screens, you can:

■ Modify a connection proﬁle for your router for the connection to your ISP or remote location

■ Set up IP addresses and IP address serving

■ Password–protect conﬁguration access to your Netopia 4541/4542

Accessing the Easy Setup console screens

To access the console screens, Telnet to the Netopia Router over your Ethernet network or physically connect with a serial console cable and access the Netopia Router with a terminal emulation program. See “Connecting

through a Telnet session” on page 5-2 or “Connecting a console cable to your router” on page 5-3.

Note: Before continuing, make sure you have the information that your ISP or network administrator has given you for conﬁguring the Netopia Router.

The Netopia Router’s ﬁrst console screen, Main Menu, appears in the terminal emulation window of the attached PC or Macintosh computer when:

■ The Netopia Router is turned on

■ The computer is connected to the Netopia Router

■ Telnet or the terminal emulation software is running and conﬁgured correctly

A screen similar to the following Main Menu appears:

6-2 User’s Reference Guide

Netopia Router

Easy Setup... WAN Configuration... System Configuration... Utilities & Diagnostics... Statistics & Logs... Quick Menus... Quick View...

If you do not see the Main Menu, verify that:

■ If you are using a serial connection, that your serial port speed is the same as the Netopia 4541/4542’s

default 9600 baud, for ﬁrst use.

■ The computer used to view the console screen has its serial port connected to the Netopia 4541/4542’s

Console port or an Ethernet connection to one of its Ethernet ports. See “Connecting a console cable to

your router” on page 5-3 or “Connecting through a Telnet session” on page 5-2.

■ Telnet or the terminal emulation software is conﬁgured for the recommended values.

■ If you are connecting via the Console port, your computer’s serial port is not being used by another device,

such as an internal modem, or an application. Turn off all other programs (other than your terminal emulation program) that may be interfering with your access to the port.

■ You have entered the correct password, if necessary. Your Netopia 4541/4542’s console access may be

password protected from a previous conﬁguration. See your system administrator to obtain the password. See Appendix A, “Troubleshooting,” for more suggestions.

Quick Easy Setup connection path

If your ISP assigns your Router a Static IP address, do the following:

1. Open a Telnet session to 192.168.1.1 to bring up the Main Menu. If you don't know how to do this, see “Connecting through a Telnet session” on page 5-2. Alternatively, you can connect the console cable and open a direct serial console connection, using a

terminal emulator program. See “Connecting a console cable to your router” on page 5-3.
