Description (partial)

Catalyst 6800IA Client fails to bootup after installation or upgrade.
IA Client's System LED stuck in blinking green.

On detecting image mismatch (between IA Parent and Client), old image gets deleted in the Client as part of the upgrade process. If any issue  (e.g., module to which the client connected resets, link(s) between the client and parent flaps, client is power-cycled etc.) that could interrupt the image download process occurs, it could get the client stuck in "switch:" prompt and fail to boot (as no valid image is present)
