 Hello, this is Jonathan Davis with the National Consortium for Mission Critical Operations. Today we're going to talk about how to install a wide area network interface card, our WIC, into the WIC slot on a Cisco 1841 router. Let's get started. Okay, so we're going to cover how to install this wide area interface card, smart serial adapter, into slot one of the Cisco 1841 router. I've loosened these screws up here so that I can just unscrew them with my thumb so that we can remove the blank slot here. Here we have the wide area interface card. We're going to line it up with the little slots on the side and then we're going to push it in. Once we push it in, we're going to give it a good push in so that we know that the connection is firm on the inside. And then we're going to, with our thumbs, screw the screws back in on the slot to hold it in place. And that's how you install a wide area network interface card, our WIC, into the WIC slot of this 1841 Cisco router.
