Cisco Systems 850 Series, 870 Series quick start Connect the Router

Chapter 1 Cisco 850 Series and Cisco 870 Series Access Routers Cabling and Setup Quick Start Guide

Connect the Router

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 7 Cisco 871 router only: Connect supported USB devices such as flash memory modules or eTokens to the two USB ports. For more information, see the Cisco Access Router USB Flash Module and USB eToken Hardware Installation Guide. Proceed to Step 12.

Step 8 Cisco 857 and Cisco 877 routers only: Connect the ADSLoPOTS port on the router to the telephone wall jack by using the lavender DSL cable. If the ADSL line is also used for voice communication, you can prevent disruption to data communication by connecting the router to an ADSL splitter, or by installing microfilters between telephones or fax equipment and the wall jack. Proceed to Step 12.

Caution Both LAN and WAN ports can use RJ-45 connectors. Use caution when connecting cables to these connectors. To avoid damage to the router, do not connect telephone-network voltage (TNV) circuits (such as ISDN or DSL circuits) to safety extra-low voltage (SELV) circuits (such as LAN circuits).

Step 9 Cisco 876 and Cisco 878 routers only: For dial backup and remote management, you can connect the ISDN S/T port to a Network Termination (NT1) box or an ADSL splitter, using the orange ISDN S/T cable (ordered separately). Continue to Step 10 or proceed to Step 11, as appropriate for your router model.

Step 10 Cisco 876 routers only: Connect the DSL cable to the ADSLoISDN port on the router and to the ADSL splitter or wall socket. If you are using an ADSL splitter, connect the splitter to the wall socket using a Category 5 unshielded twisted-pair cable. Proceed to Step 12.

Step 11 Cisco 878 routers only: Connect the DSL cable to the G.SHDSL port on the router and to the wall socket.

Step 12 All router models: Connect power to the router, and turn on the router. Be sure to use the power supply that was shipped with the router. Other power supplies will not connect to the router.

The green OK LED on the front panel of the router lights up when you connect the router to a power source. The router is now ready for use.

If the green OK LED does not turn on, see the “Troubleshooting” chapter in the Cisco 850 Series and Cisco 870 Series Routers Hardware Installation Guide.
