Cisco CT2504 console port not responding

I have a Cisco CT2504 wireless controller, and I am unable to configure it because I am not getting a response on the console connection.

Also, there's no fault light showing, pwr, sys lights are green.

this is what I have captured from the controller:

        Parameter Request List Item: (150) TFTP Server Address
    Option: (255) End
        Option End: 255

Is there anything I can do about this to be able to complete the setup of this controller?

Is that what you get from the console while it's booting?
pajkicoPresidentAuthor Commented:
Well, I have captured this during the boot or later on. I was using wireshark, but I am not sure if I was sniffing all the traffic...
pajkicoPresidentAuthor Commented:
I was wondering if I provide everything from those requests, would the WLC pickup the configuration and the rest?

Craig BeckCommented:
No not really. The 2504 won't use an address from DHCP - it's static IP only.

How are you configuring your terminal program and what cable are you using to connect to the console of the WLC?
pajkicoPresidentAuthor Commented:
I am using putty with the serial option. 9600 baud, 8 data bits, 1 stop bits, parity - none, flow control - none
pajkicoPresidentAuthor Commented:
also, I am using blue console cable plus the usb-to-serial, connection works with my other cisco devices connected to console port
pajkicoPresidentAuthor Commented:
well, the new CT2504 could be configured from port 2 on the controller, if you connect the computer directly to port 2 of the controller, the controller issues an IP address to the computer (, and in turn you can connect to WLC on address to do the first time express setup...
Craig BeckCommented:
Ok so you've got new-ish code on it then.

Console port should still work though.
pajkicoPresidentAuthor Commented:
no, not really. Pushing the "reset" button on the front only reboots the controller, and for the above to work it has to be reset to factory settings. I just got the new controller, and the instructions were as above to do the express setup
Craig BeckCommented:
What do you mean "not really"?

Express setup is a fairly new thing on the WLCs. The console port is ALWAYS enabled. If it doesn't work it's either your laptop, serial port, cable or the WLC needs RMAing.

The express setup was simply added to help less technical people get a WLC going with a basic config.
pajkicoPresidentAuthor Commented:
I mean, I was referring to the one that I have problem with. For the new one I acquired, I used express setup from port 2 of the controller.

The fact is that even though I have setup the new controller - I still can't connect to it's console port?
pajkicoPresidentAuthor Commented:
Since I have no problem connecting to the console port of my cisco 2811 router, I am assuming that my console port settings are correct?
Craig BeckCommented:
The console port settings are correct. I'd RMA the WLC.
