Hello There,I am a CCNA student and and really want to practice and learn, I bough a Cisco Switch 2960, I was able to configure this with the Ethernet port... using Telnet... now I Bough a Router Cisco 1801, Series 1800... I am not able con access the CLI, I have a Desktop with windows 7, that one has a serial port to connect the console cable... I installed PuTTY and configure the PuTTY for Serial and speed as the manual says... but I can't get access... I just get a message saying Error.. Can not open Com1... the same with the switch... any suggestions? Another Question... Its normal that when I turn on the Router and haven't connected any cables yet the CD LED in from is Blinking? and the Router makes a constant noise like a Click...
Computer OS: Windows 7
I tried connecting the Router to the Switch... but the only port that turn on the light in the Router when I connect to the Switch is FE0... I tried the normal ethernet ports but in the switch I can see the light does not even turn on...
My presumption is that you are trying to connect to the CLI through a serial port right now.
You need to make sure that your baud rate is correct.
You can also try a hyperterm session.
Make sure you are set to 8-bit, 1 stop bit, 9600 baud, with the hardware handshake turned off.
Also, it is completely normal for that LED to light up.
However, it is on when the device is physically connected. Blinks when the connection has a problem.
Most likely because nothing it plugged in.
I'm trying to connect with the Console Cable
Through the com port?
in the console port of the router... and serial in the desktop
Yeah, you need to make sure of your baud rate
That is the most likely cause of a bad connection.
and open PuTTY and selected ... Serial connection .... 9600..... 8 bit...
Where exactly is it failing?
but when I check the Device Manage in the pc... I can't see any COM ports... but there is the serial one that came integrated in the board...
Can you post a screen shot?
how can I enable that COM1
OK, there is your problem
I'm using Windows 7
Even if the device is integrated, if it doesn't show up in device manager it is either not physically connected or not installed.
It could have been disabled.
So in the Device Manager, under Com& LPT ports, what DOES show up?
I don't see that option...
so in the menu action
i selected add legacy hardware
OK, right click on your computer name on the top of that window, and select Scan for New Hardware
yeah, it does not detect any new hardware
It will not be in the Add Legacy Hardware
The only thing you can conclude from this is either that com port is not connected, or it is a bad port.
If it is not connected, it may be as simple as purchasing a cable, and making sure it is plugged into the appropriate port on your motherboard.
ok... in that case... if that port is not working...
I have another cable
but this one is RJ45 in one end
To go from the ethernet port to the console?
and the same RJ45 in the other end
can I use this one to connect the console
I do not think so, no.
I will verify.
Hold on just a moment.
No, this will not work.
Do you have another workstation?
Laptop or something like that with a working COM port?
I only have one pc with that serial port
Wow, we are kind of stuck.
well computers now does not come with that port
The two possibilities you are left with for that workstation both lead directly to hardware troubleshooting.
I have a Toshiba laptop as well
You can also get a card with a serial port for a very low amount of money.
but it does not have that port
And the laptop has no com port?
The expansion cards cost about 12 dollars
You can go that route, or you can go with hardware troubleshooting on your workstation.
But if the port is bad, and it is integrated into your board, there won't be a fix for it short of replacing the motherboard.
If it is just a cable, you'd be looking at the cost of that cable (4-15 dollars) plus the diagnosis fee for whoever you took it to to get it fixed.
That can be anywhere from 30-80 dollars
I see... so there is no way to connect to the router without that console cable ?
The only way to use the Ethernet port is if there is ANOTHER port on the router that is a separate ethernet port called a management port.
The 1800 series does not have this.
At least not be default.
no be default
I am sorry, I wish I had better information for you, but you cannot connect through the com port when the com port isn't there and recognized by the operating system.
so what I have to try now is another serial port... so the problem here is actually the port on my pc right ?
You need to get the operating system to see a com port. It will give it a number automatically. (It might wind up being 2)
Then putty or hyperterm will work
yeah I will try to find a friend with an old pc with that port because my toshiba portage does not have the serial port
I am sorry
I wish I could be of more help.
But at least we were able to pinpoint your problem
yes. Thank you anyway! at least now I know a bit better where the problem is
Thank you very much!
