b. Connect the other end of the separate power cord to a power outlet.

If you have a router with the PoE option, you must connect the PoE power supply to the PoE socket on the

Note

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.

The example in Figure 2 shows connectivity to a hub. The router Ethernet switch ports can be connected to

Note

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.

To use Cisco Router and Security Device Manager (SDM) to configure your router, you must connect a PC to the first

Step 3

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.

Always connect the Ethernet cable to an Ethernet port on the router. Accidentally connecting the cable to the wrong

port can damage your router.

To connect the router to your service provider network, connect one end of an Ethernet cable to a 10/100 Fast Ethernet

Step 4

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.

(Optional) The Cisco 1811 router supports a 230-kbps dialup connection to your service provider network through its

Step 5

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.

To configure your router for a backup dialup connection, you must use the Cisco IOS command-line

Note

interface (CLI). For more information, see the Cisco 1800 Series Integrated Services Routers (Fixed) Software
