2 Overview
This document describes the steps for installing your Cisco 1721 router with its complement of WAN interface cards (WICs).
Additional documentation can be found on Cisco.com.
Product Serial Number Location
The serial number label for Cisco 1721 router is located on the rear of the chassis, to the right of the power switch.
3 Parts List
Your router package should include the following items:
•One Cisco 1721 router
•One blue RJ-45-to-DB-9 console cable
•One DB-9-to-DB-25 adapter
•One black power supply
•One black power supply cord
•Product documentation
Items You Need to Provide
Depending on your network environment, you may need to provide some of the following items to install the router:
•Ethernet hub or switch to connect the router to the local network
•Straight-through Ethernet cables (RJ-45-to-RJ-45) to connect the router to a broadband (xDSL or cable) modem and to a
hub or switch
•Cisco WIC(s), if you did not order the router with WICs already installed
•Cables to connect WICs to the appropriate WAN services
•External NT-1 or data service unit/channel service unit (DSU/CSU), if needed, to connect a WIC to WAN services
4 Connect the Power Supply
Follow these steps to connect the router to the power supply:
Step 1 Connect the attached power supply cord to the power socket (labeled +5, +12, -12 VDC) on the back panel of the
router, as shown in Figure 1.

Step 2 Connect the separate power cord to the power socket on the power supply.
Step 3 Connect the other end of the separate power cord to a power outlet.
Step 4 Turn on the router by pressing the power switch to the on ( | ) position.
Step 5 Confirm that the router has power by checking that the PWR LED on the front panel is on.
5 Connect the Router to Your Local Network
You need to provide straight-through Ethernet cables for connecting the router to the local Ethernet network. For more
information on these cables, refer to the “Cabling Specifications” chapter in the hardware installation guide that came with the
router. Follow these steps to connect the router to your local network:
Step 1 Connect one end of an Ethernet cable to the 10/100 ETHERNET port (the yellow port) as shown in Figure 2.
Caution Always connect the Ethernet cable to the Ethernet ports on the router. Accidentally connecting the cable to the
wrong port can damage your router.

6 Installing the WICs
Look for a WIC in one or both of the slots on the back of the router. If a card is already installed, it can be connected to a WAN
line in accordance with the <Emphasis>Cisco WAN Interface Cards Hardware Installation Guide that came with the card. To
install a card in either slot, follow these instructions.
Note If you are installing a WIC in the router for the first time, install the card in the WIC0 slot to ensure that your software
configuration will not be affected if you install a second card at a later time.
Step 1 Set the power switch to the STANDBY ( ) position and confirm the router is not connected to the power supply.
Caution Power must be removed from the system prior to installing or removing WICs to avoid damaging them. When WICs
are pushed into or pulled out of a router that is powered up, it is likely that they could be damaged electrically and
will no longer function.
Step 2 Remove the screws that hold the slot cover in place, as shown in Figure 3, and then remove the slot cover. You should
be able to loosen the screws using your fingers; however, if the screws are very tight, you might need to use a Phillips
screwdriver.

7 Connecting a PC to the Router
In order for the Cisco IOS software to be used to configure the router, the router must be connected to a terminal or a PC with
terminal emulation software. Terminal emulation software should be configured with the following settings: 9600 baud, 8 data
bits, no parity bits, and 1 stop bit. The Cisco 1700 Router Software Configuration Guide describes how to configure the router
by using Cisco IOS software.
Note If it is installed on your router, you can use Security Device Manager, a web-based configuration tool, to configure your
router. If you want to use Security Device Manager, skip this section, and complete sections 8 and 9. If you want to use
the Cisco IOS command line interface (CLI), you can use the information in this section to connect a PC to the router’s
console port so that you can access the IOS CLI.
Follow these steps to connect the router to a terminal or PC:
Step 1 Connect the RJ-45 end of the included console cable to the CONSOLE port on the back panel of the router, as shown
in Figure 5.
Figure 5 Connecting the Console Cable to the Router
Step 2 Connect the DB-9 end of the console cable to the console port (also called the serial port) on your PC. If this adapter
does not fit your PC console port, you must provide an adapter that fits.

8 Verify Your Installation
You can verify that you have correctly installed your router by checking the LEDs as described in Table 1.
9 Configure the Router Using Cisco Router and Security Device Manager
Cisco Router and Security Device Manager (SDM) is a web-based configuration tool that allows you to configure LAN
and WAN interfaces, routing, Network Address Translation (NAT), firewalls, VPNs, and other features on your router.
If SDM is installed on your router, configure the router by following the instructions in the Cisco Router and Security
Device Manager (SDM) Quick Start Guide. If this document was not shipped with your router, you can obtain SDM and
instructions for installing it on your router from the following location:
http://www.cisco.com/pcgi-bin/tablebuild.pl/sdm
To obtain the SDM release notes, and other SDM documentation, go to http://www.cisco.com/go/sdm and click the Technical
Documentation link.
Table 1 LEDs That Verify Installation
LED Panel What to Look For
PWR Front On when power is being supplied to the router.
OK Front On when the router software is loaded and
functional.
Blinking when the router is running a power-on
self-test (POST). Continual blinking can indicate a
problem with the router, although the LED will
also blink if the router is in ROMMON mode.
Refer to the “Troubleshooting” chapter in the
Cisco 1721 Router Hardware Installation Guide
for more information.
LINK Back On when the router is correctly connected to the
Ethernet network through the 10/100
ETHERNET port.
FDX Back On when the Ethernet port is operating in
full-duplex mode.
100 Back On when the 10/100 ETHERNET port is
operating at 100 Mbps.
ETH ACT Front Blinking when there is network traffic on the local
Ethernet LAN.
WIC0 ACT and WIC1 ACT Front On solid or blinking when there is data traffic on
the corresponding WIC port. Refer to Table 1-4 in
Chapter 1, “Cisco 1721 Router Overview,” of the
Cisco 1721 Router Hardware Installation Guide,
for detailed information.
WIC0 OK and WIC1 OK Back On when a WIC is correctly installed in the
corresponding WIC slot.
MOD OK Back On when the VPN hardware encryption module is
installed and recognized by the IOS.
