Chapter 9 Installing Interface Cards in Cisco 1800 Series Routers (Modular)

Installing WICs, VWICs, and HWICs

To install a card in a Cisco 1841 router, follow these steps:

Step 1 Make sure that the router is turned off and is disconnected from power.

Caution Power must be removed from the system prior to installing or removing interface cards to avoid damaging them. When interface cards are pushed into or pulled out of a router that is powered up, there is a strong possibility that they could be damaged electrically and would no longer function.

Step 2 Loosen the thumbscrews on the interface card blank faceplate on the back panel, as shown in Figure 9-1. 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.
