![]() Once you’ve got your equipment, you need to get the right cabling together. ![]() You can use that to connect the appropriate management cable up to the back of your Cisco device. One end is USB, the other is a com port, install the driver that way you have an extra com port connected to your laptop. So what you do is you just get an adapter. All you need to do is most laptops these days will have a USB port on the side or on the back, something like that, but most of them are not going to have a com port. Now one thing about the laptop, you don’t want to freak out if you don’t have a serial port on your laptop and you got a CCNA level job going in configuring a Cisco device somewhere. I use my laptop when I go in and I am using the necessary cabling I will need to be able to connect up to the back of the router or switch that I will be working on. The first thing that we’re going to need aside from a laptop or computer with a serial port and/or actual router or switch we’re configuring is we’re going to need the right cabling that allows us to connect from our laptop or our computer to the device that we’re going to be configuring. The CCNA router or switch will interpret those signals and allow us to go in and configure the device. Now what we’re after is using the Hyperterminal program to send signals out of this serial interface on the back of your computer into the RJ45 jack on the back of the router. The console port is the only port that you can plug into right away when the device is previously un-configured and this will give you access to the operating system so we can go in and configure our device. You can actually plug a modem into this port and use it to dial into the device remotely when network connectivity is down. Now right here it’s a little hard to see, it actually says “console” and what will happen is most Cisco devices will have a blue oval next to the port and it will say, “console.” The one below it is an auxiliary port that can be connected into. The console port on the back of the router or again maybe on the front of the router depending on the device is an RJ 45 jack. This is a DB9 meaning D shaped, 9 meaning 9 pins in there, male connector on the back of your computer used for different serial type of connection devices. Now the one on the back of the computer is your communication ports, the com port. One would be on the back of your computer, the other on the back of the router or the back of the switch, sometimes on the front of the router or the switch depending on the model number. Now I’ve brought up a couple of pictures of some ports that you’re going to see. Let’s go in and take a look at some of the ports we’re going to see on the back of your computer that you’ll be using as well as the ports on the back of the router. And then lastly troubleshooting our physical access connection method. ![]() What type of cabling we can use, Hyperterminal Settings, Hyperterminal simply, and access program that allows us to use our com port to send and receive signals to a device. Now what we’re going to do is we’re going to actually go in and take a look at the ports that we can use to go in and access the operating system on the device as this is a critical CCNA skill. So first thing you have to have is physical access to the device. Second, type AT+CGDCONT? to verify the configuration works.Now as I’ve said this is a physical device configuration method or an end connection method. Following is an example on how to configure UE works in IPv6:įirst, type AT+CGDCONT=3,”IPV6”,"vzwinternet” to configure IPv6.If you get "OK" response, that is UE responds to AT command, and you can give more AT command. Configure ASCII settings on HyperTerminal window by selecting File | Properties | Settings (tab) | ASCII Setup, check all the items:.In our case the port number is COM111. Click OK to close this window (Also click OK on the rest windows untill you see the HyperTerminal window). HyperTerminal is located in Start | Programs | Accessories | Communication.Ĭhoose the port number in drop down box "Connect using". Open the HyperTerminal, which is a communication utility on Microsoft Windows OS.Find the port in use by selecting the modem tab, in our case the port number is COM111:.Open Device Manager and check the Modems section, right click on Pantech UML290 USB Modem and choose properties: Pantech UML290 requires using AT Command with HyperTerminal.
