THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

Preparing for Installation

This section provides information on safety, mounting the router, and unpacking the contents of the router box.

Safety

This section provides safety warnings and electrostatic and router damage information for the Cisco 827 routers and SOHO 77 routers.

Warnings

Before installing the router, read the following warnings:

Chapter 2 Installation

Warning

Only trained and qualified personnel should be allowed to install or replace this equipment.

Read the installation instructions before you connect the system to its power source.

Before working on a system that has a standby/off switch, turn the power to standby and unplug the power cord.

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

Ultimate disposal of this product should be handled according to all national laws and regulations.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different electrostatic potentials, such as an operator and a piece of electrical equipment. It occurs when electronic components are improperly handled, and it can damage equipment and impair electrical circuitry. Electrostatic discharge is more likely to occur with the combination of synthetic fibers and dry atmosphere.

Always use the following ESD-prevention procedures when removing and replacing components:

Step 1 Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good skin contact.

Caution To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

Always observe the warnings in the preceding section, “Safety.”

Step 2 Do not touch any exposed contact pins or connector shells of interface ports that do not have a cable

attached.

If cables are connected at one end only, do not touch the exposed pins at the unconnected end of the cable.

Preparing for Installation

Note This device is intended for use in residential and commercial environments only.

Caution Periodically check the resistance value of the antistatic strap, which should be between 1 and 10

megohms (Mohms).

Configuring the Router

When you have finished installing the router, you must configure the router software. First, check PC configurations to ensure that all PCs will be able to communicate with the router. Then configure the router software using the web interface.

Checking the PC Configuration

Each PC that is connected to the router must be configured to use the Transmission Control Protocol/Internet Protocol (TCP/IP) and to obtain its IP address automatically. Follow these steps to configure each PC that is running Microsoft Windows NT or Microsoft Windows 95 or 98. If the PC is running a different version of Microsoft Windows, refer to the documentation that came with the PC.

Step 1 Start the PC, and open the Control Panel.

Step 2 Click the Network icon to display the Network window.

Step 3 Verify that TCP/IP has been added and associated with the Ethernet adapter. TCP/IP is shown as a cable

icon in the Configuration window on Microsoft Windows 95 and 98; it is shown as a cable icon in the Protocol window on Microsoft Windows NT. If the icon is not visible, click Add, and add the Microsoft TCP/IP protocol.

Chapter 2 Installation

Step 4 To verify that the PC is configured to obtain an IP address automatically, click the TCP/IP cable icon,

and select the IP address tab in the TCP/IP Properties window. Check Obtain an IP address from a DHCP server if it is not checked. The IP address and Subnet mask fields should be greyed out.

Step 5 Click OK to accept all changes and exit this window, and click OK in the Network window.

Step 6 To reboot the PC, click Yes if you are prompted.

For more information on how to configure TCP/IP, refer to the Cisco Router Web Setup Troubleshooting Guide, which is available on the Cisco 800 and SOHO Series Product Documentation CD.

Using Cisco Router Web Setup to Configure the Router

Cisco strongly recommends that inexperienced network administrators use the Cisco Router Web Setup application that has been installed on the router. To use this application, complete the following steps:

Step 1 Start, or restart, one of the PCs connected to the router through ETHERNET port 1, 2, 3, or 4.

Step 2 Open a web browser. Make sure that your browser is set to work in online mode.

• In Internet Explorer, click the File menu, and verify that the work offline option is unchecked.

• In Netscape, the default selection in the File menu is set to work online.

Step 3 Type in the universal resource locator (URL) http://10.10.10.1. The CRWS home page will appear in

one or two minutes.

Tip If the CRWS home page does not appear when you enter the URL http://10.10.10.1, test the connection

Configuring the Router

between the PC and the router by doing the following:

1. Check that the OK LED on the router is on, and check the cable connection between the router and

the PC. Be sure that the TO HUB/TO PC button is in the correct position. The button is in the correct position if the LED for the port on the front of the router is on.

2. If the CRWS home page still does not appear, verify that the web browser’s “work offline” option

is disabled.

3. If the web page still does not appear, verify that your PC is automatically configured to receive an

IP address. Follow the instructions in the Cisco Router Web Setup Troubleshooting Guide, which is available on the Cisco 800 and SOHO Series Product Documentation CD.

4. If the PC is configured to automatically receive an IP address, but the web page still does not appear,

select Start/Run, type winipcfg in the Run window, and examine the address in the IP address field. The address should be in the format 10.10.10.X, in which X is a number that is equal or greater than 2; for example, 10.10.10.2, or 10.10.10.3. If the IP address is not in this format, verify that an Ethernet adapter name is visible in the Adapter field. If there is no name in the field, return to Step 3 in “Checking the PC Configuration," add TCP to the list of protocols. Then return to “Using Cisco

Router Web Setup to Configure the Router, page 2-16," and complete the procedure.

Step 4 If you have no special configuration requirements, click the Router Setup link on the home page, and

then click Easy Setup. (This may appear as Quick Setup on some models.) Then, enter the user name and password provided to you by your Internet service provider, and click Apply.

Step 5 If you need to configure special features such as Network Address Translation (NAT), click the

appropriate links on the home page, and complete the configuration screens.

Step 6 Click the Password link on the home page, and set a password for the router.

Step 7 Click the Tes t Co n nec t ion link on the home page, and allow the connection to be tested.

Step 8 Select Start/Run, and type winipcfg in the Open field of the Run window. When the IP Config window

appears, click Release to release the PC’s IP address. Then click Renew to renew the PC’s IP address.

Alternatively, open the Run window and enter ipconfig /release to release the PC’s IP address.Then enter ipconfig /renew to renew the IP address of the PC.

Step 9 Open a web browser on the PC, and connect to a website.

The router installation is complete when you have connected to a website.
