Greetings, I'm trying to connect to a Cisco 2900 Series Switch from a Windows 7 Pro box via serial to rj-45, using Putty and not able to connect.
I found this video via youtube and did everything he did and I'm not able to connect.
YouTube - Using Putty for Connecting to Cisco Devices
I noticed that Windows defaults to com1 and I changed that to com3 like the example and it still isn't working.
When using Google noticed a few threads saying that legacy hardware, like the serial port is going the way of the dinosaur...so with that being said was wondering if anyone has an issue like this and if they were able to work thru it or should I just get usb to rj-45 cable?
thanks

If you want RS232 serial on a machine that doesn't come with it built in then you have to use a USB serial adapter or buy a RS232 serial expansion card to fit into your computer. USB serial adapters will generally require a driver but not all of them do.JockVSJock wrote: »so with that being said was wondering if anyone has an issue like this and if they were able to work thru it or should I just get usb to rj-45 cable? -
Optionstiersten Member Posts: 4,505Does your machine have a built in serial port?
What specific cable are you using to go from the serial port to the console port on the switch?
You sure that the switch console port actually works?
Got to ask but you are plugging this cable into the console port? -
OptionsTheSuperRuski Member Posts: 240I had to use the usb to serial cable to dial into a router from Windows 7 but that was because my laptop doesn't have the serial port on it. It required a driver download as tiersten said. You also you have to find the right COM port you are plugging into. I use tera term and by default it uses COM port 1. The one that worked for me was COM 12. I would go down the list of available connections and test them all.

If you look in the device manager, it'll tell you which port number it's using. -

Yes, shows up under Device Manager as com1. I've also tried com3 and still didn't work.What specific cable are you using to go from the serial port to the console port on the switch?
Cable is a serial to rj-45 cable.You sure that the switch console port actually works?
I'll try my 12 port switch.Got to ask but you are plugging this cable into the console port?
I've tried both the console port and a few of the ports on front of the switch and no dice.
I've also tried connecting to the 12 port switch using both com1 and com3 and still not able to connect.
Keep getting the following errorunable to open connection to COM1 Unable to open serial port

OptionsJockVSJock Member Posts: 1,118Ok, I'm not a Windows 7 expert, however I was able to get connection to my Cisco Switch via a Linux Live Disk (Knoppix) and Minicom. Ran the live disk from the Win 7 box.
Not sure where the issue is with Windows, however Linux has saved the day again.***Freedom of Speech, Just Watch What You Say*** Example, Beware of CompTIA Certs (Deleted From Google Cached)
