This chapter provides information on the following topics:
•Preventing Damage to the Router
•Using the Router LEDs to Check Links
This section provides information on safety, mounting of the router, and unpacking of the router box.
This section provides safety warnings and electrostatic and router damage information for the Cisco 836 and Cisco SOHO 96 routers.
Before installing the router, read the following warnings:
Warning Only trained and qualified personnel should be allowed to install or replace this equipment.
Warning Read the installation instructions before you connect the system to its power source.
Warning Before working on a system that has a standby/off switch, turn off the power switch to standby and unplug the power cord.
Warning 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.
Warning 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.
Warning During this procedure, wear grounding wrist straps to avoid ESD damage. Do not directly touch the backplane during with your hand or any metal tool, or you could shock yourself.
Warning This equipment is not designed for making emergency telephony calls when the power fails. Alternative arrangements should be made for access to emergency services. Access to emergency services can be affected by any call-barring function of this equipment.
Warning To reduce the risk of fire, use only No.26 AWG or large telecommunication line cord.
Warning This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 port, or the associated circuit-board when the ringer is active. The ringer is activated by an incoming call.
Warning Ths ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers.
Warning Network hazardous voltages are present in the ISDN cable. If you detach the ISDN cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the ISDN port (RJ-45 connector), regardless of when power is turned off (by pressing power switch to standby).
Warning Ultimate disposal of this product should be handled according to all national laws and regulations.
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 follow these steps to prevent ESD when you remove and replace components:
Step 1 Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good skin contact.
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.
Note This device is intended for use in residential and commercial environments only.
Table 2-1 lists the items that come with your router. All these items are in the accessory kit that is inside the box that your router came in. If any of the items is missing or damaged, contact your customer service representative.
To prepare for installation, follow these steps:
Step 1 Remove yellow Ethernet cable, light blue console cable, and product documentation from the accessory kit. Remove the desktop power supply, orange ISDN S/T cable, the lavender ADSL cable, and the black power cord from the box. Gather the Ethernet devices to be connected to the router: hub, server, workstation, or PC.
Step 2 If you plan to connect an analog telephone or fax machine, gather these devices. You must also provide the telephone cable to connect each device.
Step 3 If you plan to configure the software using a terminal or PC connected to the router, provide the terminal or PC.
Note Unless otherwise specified, a lavender straight-through RJ-11to RJ-11 cable is provided as the ADSL cable. The user can select one of two other cables instead—a crossover RJ-11 to RJ-11 ADSL cable or a straight-through RJ-11 to RJ- 45 ADSL cable. Each router is supplied with only one ADSL cable, which the user selected during the ordering process.
Note The optional orange ISDN S/T cable used for connecting a Cisco 836 router's ISDN port to the ISDN service provider is for dial backup and remote management. The Cisco SOHO 96 router needs this cable for remote management. The user may order this optional cable additionally.
Note There are six different power cords. Each was designed to meet the specifications of the cable wall jack for a particular country. Each of the six power cords is different from the others. The default cord shown in Figure 2-1 is European Union standard specification.
Follow these guidelines when connecting devices to your router:
•Connect the color-coded cables supplied by Cisco Systems to the color-coded ports on the back panel.
•If you must supply your own cables, see Appendix A, "Specifications and Cables," for cable specifications. If this appendix does not provide specifications for a particular cable, we strongly recommend that you order the cable from Cisco Systems.
•If the symbol of suitability () appears above a port, you can connect the port directly to a public network that follows the European Union standards.
Warning If the symbol of suitability with an overlaid cross () appears above a port, you must not connect the port to a public network that follows the European Union standards. Connecting the port to this type of public network can cause severe injury or damage to your router.
To install the router, you need to perform the following tasks in the following order:
1. Connect the Ethernet devices to the router.
2. Connect the ADSL line.
3. Connect a terminal or PC to the configuration port of the router if you are troubleshooting or configuring the router by using the command-line interface (CLI).
4. Connect the router to the power source and turn on the router.
5. Verify the links, using the router LEDs.
You can use a cable to connect an Ethernet devices to the router's LAN port.
Follow the steps given after Figure 2-1 to connect the router to a PC with an Ethernet network interface card (NIC) installed, or to connect a server or workstation to the router. (Figure 2-1 shows a Cisco 836 router, but it also applies to a Cisco SOHO 96 router. The procedure applies to both the Cisco 836 router and the Cisco SOHO 96 router.)
The Ethernet port on the Cisco 836 router and the Cisco SOHO 96 router supports the auto-crossover function, whose autosensing ability allows the router to connect automatically to the hub or PC.

The following conditions must be met when you mount the router:
•Because you will use the LEDs as status and problem indicators, the LEDs on the front panel must face upward and must be easily visible.
•The back panel must face downward to reduce strain on the cable connections.
•The power supply must rest on a horizontal surface such as the floor or a table. If the power supply is not supported, it could place strain on the power supply cable and cause it to disconnect from the connector on the router back panel.
To mount the router on a wall, follow the steps given after Figure 2-7.
Figure 2-7 Mounting the Router on a Wall
Perform the following steps to mount the router on the wall:
Step 1 Secure two screws 7 5/8 inches (19.35 centimeters) apart into a wall and 1/8 inch (0.32 centimeter) from the wall.
Step 2 Hang the router on the screws as shown in Figure 2-8.
Step 3 Place the power supply on a horizontal surface.
When you finish installing the router, you must configure the router software. First, check the PC configurations to ensure that all the connected PCs will be able to communicate with the router. Then configure the router software, using the web interface.
Each PC that is connected to the router must be configured to use 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, 98, 2000, Windows ME, and Windows XP. 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.
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 grayed out.
Step 5 Click OK to accept all changes and exit this window. Then click OK in the Network window.
Step 6 If you are prompted, click Yes to reboot the PC.
For more information on how to configure TCP/IP, refer to the Cisco Router Web Setup Troubleshooting Guide, which is available on Cisco.com.
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 Enter 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 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.
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 section, which is available on Cisco.com.
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 to 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 the "Checking the PC Configuration" section and add TCP to the list of protocols. Then return to the "Using Cisco Router Web Setup to Configure the Router" section, 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 username 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 Test Connection 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.
