C40 not booting


Having problems with our TelePresence Intergrator C40. I wasn't present for the change, but another tech changed the IP, GW, etc and rebooted through the web interface. Once it rebooted it never came back up. Connecting to the codec serial port I get the following message:

Couldn't connect to TANDBERG software.

I've attached the full boot sequence. Any ideas of how I can get an OS uploaded or to fix this?

My hands are tied, not getting a response from the vendor, I took over this system which was put in place 3 months ago and I'm unable to get ahold of the people that coordinated the install. The S/N is registered to another support contract not covered under any of my contracts associated with my profile when trying to open a TAC and I'm getting alot of heat to get this thing fixed ASAP.

Thanks for any help!



I change folder name to:

C:\Program Files\Cisco Systems\Cisco TFTP Server\pkgfile

ok, then make sure all the required files are in the folder.  you might want to try to re-download the TC software and try again.  Assuming your tftp server is set up correctly and the server root directory is pointing to the server.

If still cannot, you might want to consider opening a TAC case for the TAC to assist you maybe over a web-ex session

still same problem, - I just download new




How we can meet web-ex session?


Raised a TAC case with Cisco and any available TAC will be able to advise you on troubleshooting over web-ex

Hi again, I uploded software sucessful - Just install SolorWind TFTP server and everything become good. So Thanks for help
