Nonwireless Routers
Portions of this guide do not apply to nonwireless models of the Cisco 850 series
and Cisco 870 series routers. Some illustrations show the router with antennas
attached, whereas the nonwireless routers do not have antennas or antenna
connectors on the back panel. However, except for the “Connect the Antenna to
the Wireless Router (Optional)” section, the connection procedures are the same
for wireless and nonwireless router models.
Read the Safety Warnings and Guidelines
Before you begin to connect your router, read the Regulatory Compliance and
Safety Information for Cisco 800 Series Routers document that is shipped with the
router. This document provides important safety warnings and guidelines.
Remove the Caution Sticker
Locate the yellow caution label that covers the LAN ports. Simply peel off the
label and the LAN ports are ready for use. Be sure that you do not connect ISDN
telephone lines to these LAN ports.

Connect the Power-over-Ethernet Module to the
Cisco 870 Series Router (Optional)
Power-over-Ethernet (PoE) is supported on the Cisco 870 Series routers only. If
you purchased a PoE module, connect all four Ethernet cables on the PoE module
to the four LAN Ethernet ports on the Cisco 870 Series router. (See Figure 1-5.)
Make sure that you connect all four Ethernet cables.
If the cables are too close together for easy insertion, move the plastic cable guard
away from the connector end of the cables.
Caution To ensure proper PoE module operation, do not connect the PoE module power
supply to the PoE module before you connect the PoE module to the router.
Although Figure 1-5 shows the Cisco 871 router connected to a PoE module, this
connection works for all router models in the Cisco 870 series.
Note When you connect a device (such as a PC or IP phone) to the PoE module, you
may notice a 1- to 2-second delay before the LED indicator for the port comes on.

Connect the Router
Connect the Router
Connect the router, referring to the typical installation for your router model as
shown in the “Typical Installations of the Cisco 850 Series and Cisco 870 Series
Routers” section on page 1-12.
Follow these steps to connect the router to the power supply, to your local
network, and to your service provider:
Step 1 Wireless models only: Make sure that you have attached the antennas to the router
as described in the “Connect the Antenna to the Wireless Router (Optional)”
section on page 1-8.
Step 2 If you are using a PoE module, make sure that it is connected to the router (see
“Connect the Power-over-Ethernet Module to the Cisco 870 Series Router
(Optional)” section on page 1-10). Connect the Ethernet devices to the PoE
module, not to the router.
Step 3 If you are connecting more than four PCs to the router, connect the router to a
switch or hub by using a yellow Ethernet cable, as shown in Figure 1-6 through
Figure 1-9.
Step 4 Connect a PC directly to your router, as shown in Figure 1-6 through Figure 1-9.
Turn off the PC 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 5 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 need access to the router console,
connect a PC or terminal to the console port.
Note By connecting the console port to an asynchronous modem using the
optional router modem cable, you can add dial backup and remote
management capabilities to the router.
Step 6 Cisco 851 and Cisco 871 routers only: Connect the second yellow Ethernet cable
between the router Ethernet WAN port and an available port on an installed digital
subscriber line (DSL), cable, or long-reach Ethernet modem as shown in
Figure 1-6.

Chapter 1 Cisco 850 Series and Cisco 870 Series Access Routers Cabling and Setup Quick Start Guide
Connect the Router
1-18
Cisco 850 Series and Cisco 870 Series Access Routers Cabling and Setup Quick Start Guide
78-16262-04
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.

Install SDM and Configure the Router
Note For Cisco 857, Cisco 876, Cisco 877, and Cisco 878 routers, the DSL line
must have been provisioned by your service provider and must be
correctly configured. Check the carrier detect (CD) status on the ADSL
CD LED or G.SHDSL CD LED on the router. If the ADSL CD LED or
G.SHDSL CD LED does not light up, check with your service provider.
Step 13 If you have connected a PoE module to the router, connect the PoE module power
supply to the input jack on the back panel of the PoE module. The green LED on
the PoE front panel lights up and power is provided to devices connected to the
PoE.
See the Cisco 870 Series Routers Hardware Installation Guide for detailed
connection instructions.
Install SDM and Configure the Router
To install Cisco SDM for configuring the router, follow these steps:
Step 1 Connect a PC to any router LAN port, as shown in Figure 1-7, Figure 1-8 and
Figure 1-9.
Step 2 Insert the Cisco SDM software CD into the CD drive of the PC. An installation
wizard is launched from the CD. Install Cisco SDM by following the instructions
on the installation wizard user interface.
Step 3 Use Cisco SDM to configure the router by following the instructions in the
Cisco Router and Security Device Manager (SDM) Quick Start Guide.
