2 Overview
This document describes the steps for installing the Cisco 1811 and the Cisco 1812 integrated services routers. The Cisco 1811
and Cisco 1812 routers are fixed-configuration routers. They each include an integrated 8-port 10/100-Mbps Ethernet switch,
two onboard Fast Ethernet WAN ports, two dual USB 2.0 ports, and optional 802.11a/b/g wireless LAN support. The switch
ports and the onboard 10/100-Mbps Ethernet ports support 802.1Q virtual LAN (VLAN) encapsulation and enable you to
configure demilitarized zones (DMZs), using VLANs and Cisco IOS firewall features. The switch ports are also optionally
upgradable to include inline power support for IP phones.
The Cisco 1811 and Cisco 1812 integrated services routers provide secure Internet connectivity and dial backup if your primary
connection fails. The Cisco 1811
provides dial backup through an ISDN S/T port.
Additional documentation can be found on Cisco.com.
router provides dial backup through a V.92 analog modem port. The Cisco 1812 router
Product Serial Number Location
The serial number label for the Cisco 1811 and Cisco 1812 routers is located on the back of the chassis, above and to the right
of the power switch. You need this serial number when calling Cisco for support. To see specifically where the serial label is on
your router, go to the following link:

3 Unpacking the Box
When you unpack the box containing your Cisco 1811 or Cisco 1812 router, you should find the items shown in Figure 1.
Note The Cisco 1811 and Cisco 1812 routers have a wireless upgradable option. If this option is chosen, an antenna kit
should have been shipped with your router in addition to the items listed in Figure 1.

Items You Need to Provide
Depending on your network environment, you may need to provide some of the following items so that you can install the
router:
• 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
• Ethernet hub or switch to connect the router to the local network, or an xDSL or cable modem to connect the router to the
service provider
• Server or other computer with a network interface card (NIC) or other networked device (such as a hub or a switch) to
connect to the integrated 8-port 10/100-Mbps Ethernet switch

Follow these steps to connect the router to the power supply, your local network, and your service provider network:
Step 1 Connect power to the router as shown in Figure 2:
a. Connect the separate power cord to the power socket on the back panel of the router.
b. Connect the other end of the separate power cord to a power outlet.
Note If you have a router with the PoE option, you must connect the PoE power supply to the PoE socket on the
back of the router, connect the female end of the PoE power cable to the PoE power supply, and connect the
male end of the PoE power cable to a power outlet.
c. Turn on the router by pressing the power switch to the on ( | ) position.
d. Confirm that the router has power by checking that the SYS OK LED on the front panel is on.
Step 2 To connect the router to your network, connect one end of an Ethernet cable (RJ-45) to an Ethernet switch port
(FE 2–FE 9), and connect the other end of the cable to a port on a hub or switch, as shown in Figure 2.

Note The example in Figure 2 shows connectivity to a hub. The router Ethernet switch ports can be connected to
another networked device, such as a switch or computer with a network interface card (NIC). If you are
connecting a computer to the switch port on the router, it will take about 30 seconds for connectivity to be
established.

Step 3 To use Cisco Router and Security Device Manager (SDM) to configure your router, you must connect a PC to the first
Ethernet switch port. Connect one end of an Ethernet cable to one of the Ethernet switch ports (FE 2–FE 9), and connect
the other end to the Ethernet port on your PC.
Caution Always connect the Ethernet cable to an Ethernet port on the router. Accidentally connecting the cable to the wrong
port can damage your router.
Step 4 To connect the router to your service provider network, connect one end of an Ethernet cable to a 10/100 Fast Ethernet
port (these ports are labeled FE 0 and FE 1); connect the other end of the cable to a network port on your service
provider’s broadband (xDSL or cable) modem equipment, as shown in Figure 2.
Caution Always connect the Ethernet cable to an Ethernet port on the router. Accidentally connecting the cable to the wrong
port can damage your router.
Step 5 (Optional) The Cisco 1811 router supports a 230-kbps dialup connection to your service provider network through its
V.92 modem port. The Cisco 1812 router supports a 144-kbps dialup connection to your service provider network
through its ISDN S/T port. These connections can serve as a backup to your service provider if your primary connection
goes down. To make a backup connection to your service provider network, connect one end of a straight-through
RJ-11 cable to the V.92 modem port (for the Cisco 1811) or a straight-through RJ45 cable to the ISDN S/T port (for
the Cisco 1812) on the router, as shown in Figure 2, and connect the other end of the cable to your telephone wall jack.
Note To configure your router for a backup dialup connection, you must use the Cisco IOS command-line
interface (CLI). For more information, see the Cisco 1800 Series Integrated Services Routers (Fixed) Software
Configuration Guide.
5 Connecting Antennas to the Router RP-TNC Connectors
If your router has the wireless LAN option, connect the antennas by screwing the antenna connectors in a clockwise direction
onto the reverse-polarity threaded Neill-Concelman (RP-TNC) connectors on the back panel of the router. Figure 3 shows an
example of how to connect the swivel-mount dipole antennas to the router.
Note The location and position of your router antennas are crucial to effective wireless connectivity. For more information
about the antennas compatible with the Cisco 1801, Cisco 1802, and Cisco 1803 routers, see the online documents
located at the following URL:
