Warnings and Notes

These are how warnings and notes are shown in this User’s Guide.

Warnings tell you about things that could harm you or your device.

Note: Notes tell you other important information (for example, other things you may

need to configure or helpful tips) or recommendations.

Syntax Conventions

• This product may be referred to as the “ZyXEL Device”, the “device” or the “system” in this User’s Guide.

Document Conventions

• Product labels, screen names, field labels and field choices are all in bold font.

• A key stroke is denoted by square brackets and uppercase text, for example, [ENTER] means the “enter” or “ret urn” key on your keyboard.

CHAPTER 1

Introduction

1.1 Overview

This user’s guide explains how to configure the following ZyXEL devices:

• The P-974H model is a 4-port cable modem and router combined. It also has a USB 2.0 port allowing computers without an Ethernet connection to join your network.

• The P-974HW model adds IEEE 802.11g wireless capability allowing wireless clients to join your network.

This user’s guide refers to these models simply as the “ZyXEL Device”. Please refer to Appendix A on page 71 for a complete list of features for your model.

1.2 Internet Access Application

The ZyXEL Device is the ideal high-speed Internet access solution. It is compliant with the DOCSIS 2.0 and Cable Home 1.1 standards. The ZyXEL Device allows you to connect up to four computers to its 10/100 Mbps Ethernet ports and an additional computer to its USB 2.0 port to form your local area network and connect to the Internet. In addition, for P-974HW, wireless clients can access your network resources and the Internet.

CHAPTER 2

The Web Configurator

2.1 Overview

The web configurator is an HTML-based management interface that allows easy setup and management via an Internet browser. Use Internet Explorer 6.0 and later or Firefox 1.5 and later versions. The recommended screen resolution is 1024 by 768 pixels.

In order to use the web configurator you need to allow:

• Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in Windows XP SP (S ervice Pack) 2.

• JavaScript (enabled by default).

• Java permissions (enabled by default).

See the chapter on troubleshooting to see how to make sure these functions are allowed in Internet Explorer or Firefox.

2.2 Accessing the Web Configurator

Follow the steps below to log into the web configurator.

1 Launch your web browser. Enter “192.168.1.1:8080” as the web site address.

P-974H/HW Series User’s Guide

Chapter 2 The Web Configurator

2 Enter the user name (“user” is the default) password (“1234” is the default) or

enter the administrator user name (“webadmin” is the default) and password (“1234” is the default) and click OK.

3 You should now see the main Status screen (refer to Figure 4 on page 25).

2.2.1 Logging Out of the Web Configurator

To log out of the Web Configurator - perhaps to log in under a different account you must close the web browser in which it is displayed and then clear your browser cache. If you do not, then the next time you re-open the web page in that browser you may not have been properly logged out.

For instructions on how to empty your web browser cache, see the documentation that shipped with it.

2.2.2 Resetting the ZyXEL Device

If you forget your password or cannot access the web configurator, you will need to use the RESET button at the back of the ZyXEL Device to reload the factorydefault configuration file. This means that you will lose all configurations that you had previously and the password will be reset to “1234”.

2.2.2.1 Using the RESET Button

1 Make sure the PWR and SYS LEDs are on (not blinking).

2 Press and hold the RESET button for about 15 seconds. All LEDs (except the

WLAN LED on the P-974HW) should turn on. When you release the RESET button, the defaults have been restored and the ZyXEL Device restarts.

P-974H/HW Series User’s Guide

Chapter 2 The Web Configurator

You can also use the RESET button to restart the ZyXEL Device (without restoring the defaults) by pressing down for 2 to 14 seconds.

2.3 Navigating the Web Configurator

The following summarizes how to navigate the web configurator from the main Status screen.

CHAPTER 3

Status

3.1 Overview

This chapter describes the Status screens you can display to view firmware and system information and system logs.

3.1.1 What You Can Do in This Chapter

•The Software screen screen allows you to view the overall status of y our device (Section 3.2 on page 31).

•The Connection screen displays all of your network connection details (Section

3.3 on page 32).

•The Event Log screen provides a composite list of all system even records (Section 3.4 on page 37).

3.1.2 What You Need to Know

The following terms and concepts may help as you read through this chapter.

Acquire Downstream Channel

In order to establish a successful connection with the cable provider’s network, the ZyXEL Device must first find and lock onto a frequency for communication with the cable operator’s network. The frequency is called a channel. Communication with the cable operator’s network cannot proceed until the ZyXEL Device finds the specific channel for sending and receiving data.

Connectivity State

The connectivity state is the current status of the connection between the cable modem and your cable operator. During the initial negotiation with your cable operator’s CMTS (Cable Modem Termination System), the ZyXEL Device must establish a clear upstream and downstream channel, which it accomplishe s in a series of well defined steps.

P-974H/HW Series User’s Guide

Chapter 3 Status

To provide Internet access services, a cable provider’s CMTS gets the incoming traffic from the ZyXEL Device and routes the traffic to an ISP (Internet Service Provider) to the Internet.

Boot State

When downloading the configuration file and booting, your ZyXEL Device passes through several negotiation stages with the cable operator’s CMTS. All communication steps: TFTP, DHCP Offer/Response, and Time Server must complete in order for the configuration to be successful. TFTP is the download protocol used to install the configuration file.

If there is a problem making a TFTP connection with the cable operator’s CMTS, you will see the message Waiting for TFTP. If the ZyXEL Device does not receive a DHCP offer from the cable operator’s CMTS you will see the message Waiting for DHCP Offer. Once the Zy XEL Device has respon ded to the DHCP offer it again waits for a response from the CMTS, if it does not receive a response you will see the message Waiting for DHCP Response. If the cable operator’s time server does not respond your will see the message Waiting for Timer Server. If the download and installation of the configuration file succeeds you will see the message Operational.

Your cable modem must receive an offer of a DHCP IP Address from the cable operator’s CMTS and respond to that offer in order to set your IP Address. First your cable modem is Waiting for DHCP Offer, if the offer is received by your cable modem it responds Waiting for DHCP Response to the cable operator’s CMTS. Once a response is received your IP Address is set and can be viewed under the CM IP Address section of the Connection screen or in the Software status screen. Note that the DHCP IP Address setting must be completed successfully in order for your cable modem to download the configuration file.

Configuration File

This is the name of the cable modem configuration file downloaded from the cable operator’s CMTS using the TFTP protocol. This is a binary format file which must be DOCSIS 2.0 compliant (see RFC 2132 for additional information).

Security

Your cab le modem has features built -in to run Baseline Priv acy (BP). BP is used as a privacy mechanism to protect user data flowing ac ross the cable net work and to prevent unauthorized access to the cable operator’s CMTS data flowing across the network. BP also supports access control lists (ACLs), filtering, tunnels, spoof protection, and source IP filtering on the RF subnets to prevent users from using IP addresses that are invalid. BP security information must be included in your cable operator’s configuration file to enable security. If your cable operator did not
