Thank you Rajesh for that demonstration. For a very short process there are a couple of trip hazards that I can see.
1. Cisco uses a variety of methods to reference the source tftp image location. With it in the default "Root" we are seeing simply "."
2. At the end of the process there may be differing instructions for different models. Recent reading shows the CT2500 Range to require the "reset system" keyword to save the download and reboot the device. The reload command will remove the image that has been download to RAM only and restart the device with nothing to reference in NVRAM. (In support of a very useful video, which is now in my reference list, thank you)
