Join Denise Allen-Hoyt for an in-depth discussion in this video The Cisco 1841 router, part of Learning Cisco CLI Router Configuration.
- So I'm going to start out by exploring the physical components of the 1841 router. We're going to start by first looking at the physical components on the front of the router. So the front of the router includes the Cisco brand logo, it will be located on the top left, and the type of router would be indicated on the top right. There are two system LEDs, the system power LED, which is either off, which means there's no power, or it's blinking green, which indicates that the router is booting.
There's also a system LED, and that will either be off, which means no traffic is passing through the router, or it would be on, which means that the router's currently moving traffic through and out one of the ports. On the back plane of the Cisco router you're going to find a power input, it's on the right-hand side, and that's where you actually plug in the AC power from the wall. There's an on and off switch, and currently the on and off switch is green which means that this router is powered on.
There are two management ports, to the left, one is a console port and one is an AUX port. There are two FastEthernet ports to the left of that, as well as the LED lights that show whether or not those ports are in use. To the left of that is a USB port, for plugging in a USB drive. And then there are two network card expansion slots.
There's a slot called zero in the top right, and there's a slot, slot one, which is in the top left. The one on the right has a (mumbling) installed in it And that is for use to connect up to your wide area network with a serial cable. And the other one has a cover on it, and that's best practice is to keep a cover on any of the open slots, but if you have such a need you can put in a different card to expand the capability of the router. Below slot one, there's also a compact flash slot and directly to the right of that is a little LED that would light up if that compact slot has a card in it and it is being used.
To the right of that is an advanced integration module light and that would be on if an advanced integration module is actually installed in the router. Above that is a little Kinsington security slot and it's used to attach a security cable so that you can physically secure the router if it's in a location where it could be mocked off with. And then finally, on the very right-hand side over by the power cable, is a chassis ground connection so that you can attach a ground cable for the router if it's installed in a rack.
