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

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.
