Check Items Shipped with the Router
Do the following to verify that all required items were shipped with the router.
Step 1 Figure 1-1 shows the items included with the router. If any of the items is missing or damaged, contact your customer service representative.
Figure 1-1 Items Included with the Router
Two yellow Ethernet cables
Desktop power adapter
Light blue console cable (RJ-45-to-DB-9)
Black power cord
Light blue async modem cable for dial backup and remote management (RJ-45-to-DB-25). (ordered separately)
Step 2 Locate the product serial number.
The serial number label for Cisco 831 router is located on the rear of the chassis, at the left edge.
Figure 1-2 Product Serial Number Location
Connect the Router
Figure 1-3 shows a typical installation of a Cisco 831 router or SOHO 91 router.
Figure 1-3 Typical Cisco 831 or SOHO 91 Installation
Step 1 If you are connecting more than 4 PCs to the router, connect the router to a switch or hub using a yellow Ethernet cable, as shown in Figure 1-3.
Step 2 To connect a PC directly to your router, do so as shown in Figure 1-3. Turn the PC off so that it will obtain an IP address from the router when it is turned on. You can connect additional PCs to the remaining numbered Ethernet ports.
Step 3 The console port is a service port to which you can connect a terminal or PC in order to configure the software by using the command-line interface (CLI) or to troubleshoot problems with the router. If you want access to the router console, connect a PC or terminal to the Console port. For more information refer to the Cisco 831 and SOHO 91 Hardware Installation Guide.
Note By connecting the console port to an asynchronous modem using the optional SOHO/800 series router modem cable, you can add dial backup and remote management capabilities to the router. Refer to the Cisco 831 Router and SOHO 91 Router Hardware Installation Guide for more information.
Step 4 Connect the second yellow Ethernet cable between the router's Ethernet Internet port and an available port on an installed DSL, cable, or long-reach Ethernet modem as shown in Figure 1-3.
Follow the instructions provided with your broadband modem to determine which port on the modem to connect to. Turn on the broadband modem if it is not already turned on.
Step 5 Connect power to the router as shown in Figure 1-3 and turn on the router. Be sure to use the power supply that was shipped with the router.
The green OK LED on the front panel of the router lights when you connect the router to a power source. The router is now ready to be used.
If the green OK LED does not turn on, refer to the "Troubleshooting the Router" chapter in the Cisco 831 and SOHO 91 Routers Hardware Installation Guide.
The Cisco 831 and SOHO 91 Hardware Installation Guide contains more detailed connection instructions.
Try to Connect to a Website
Log on to a PC that is connected to the router, open a web browser, and connect to a website. If you successfully access a website, you do not need to change the configuration and you have completed setup. If you cannot access a website, follow the steps in Configure the Router.
Configure the Router
Your router was shipped with a web-based configuration tool that you run from a web browser.
SDM Configuration Instructions
If the Cisco Router and Security Device Manager (SDM) Quick Start Guide was included in your accessory kit, Cisco Router and Security Device Manager (SDM) is loaded on your router. Refer to that document to configure your Cisco 831 router.
The following link contains more information about SDM, including release notes and other SDM documentation.
Note SDM is not shipped with SOHO 91 Routers.
CRWS Configuration Instructions
If you did not receive the Cisco Router and Security Device Manager (SDM) Quick Start Guide, Cisco Router Web Setup (CRWS) is loaded on your router. These instructions show you how to configure your router using CRWS. The CRWS software runs on Netscape versions 3.0 through 4.7, and on Internet Explorer version 4.0 or later.
Step 1 Start, or restart, a PC connected to one of the built-in switch ports (1, 2, 3, or 4) on the router.
Step 2 Open a web browser. Make sure that the 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) shown in Figure 1-4.
Figure 1-4 Type in the URL http://10.10.10.1
The CRWS dashboard page (Figure 1-5) should appear after one or two minutes.
Figure 1-5 CRWS Dashboard Page
Tip If the CRWS dashboard page does not appear when you enter the URL http://10.10.10.1, test the connection between the PC and the router by doing the following:
•Check that the OK LED on the router is on, and check the cable connection between the router and the PC.
•If the CRWS home page still does not appear, verify that the web browser's "work offline" option is disabled.
•If the web page still does not appear, verify that the PC is configured to automatically receive an IP address. 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 2 or greater; for example, 10.10.10.2 or 10.10.10.3. If the IP address is not in this format, Follow the instructions in the Tip to configure the PC to obtain an IP address automatically. Then start CRWS again.
Step 4 If you have no special configuration requirements, click the Router Setup link on the home page, and then click Quick Setup. Then, enter the username and password provided to you by your Internet service provider, and follow the instructions that appear in the page that is displayed.
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 Router Password link on the home page, and set a password for the router.
Step 7 Select Start/Run, and type winipcfg in the Open field of the Run window. When the IP Config window appears, click Release, and then click Renew to release and 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 8 Open a web browser on the PC, and connect to a website. If you can connect to a website, you have completed setup.
Tip If you could not start CRWS, your PC might not be configured to obtain an IP address automatically. You can use this information if your PC is running Microsoft Windows NT or Microsoft Windows 95, 98, or 2000. If the PC is running a different version of Microsoft Windows, refer to the documentation that came with the PC.
1. Start the PC, and open the Control Panel.
2. Click the Network icon to display the Network window.
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, 98, 2000, Windows ME, and Windows XP and as a cable icon in the Protocol window on Microsoft Windows NT. If the icon is not visible, click Add, and add Microsoft TCP/IP.
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 grayed out.
5. To accept all changes and exit this window, click OK. Then click OK in the Network window.
6. If you are prompted, click Yes to reboot the PC.
7. Return to Step 3 in the "Configure the Router" section.
For more information on how to configure TCP/IP, refer to the Cisco Router Web Setup Troubleshooting Guide, which is available on Cisco.com.
Congratulations! You Have Completed Setup
If you were able to connect to a website, you have completed the cabling and setup of your router, and you can continue to use it to access the Internet. If you need to configure more features, click the CRWS link for the feature you need to configure, and enter configuration values for the router.
