[USR-TC] How to reload firmware on blank NMC?

So in my exploration of what componants are available to me to deploy this new RAS, I went through my NMC collection. I've discovered that one of my NMC units has a stick note stating "NO SOFTWARE!!!!", and when I put it in my chassis and try to boot it, it does nothing - won't even respond on the serial port. All I get is a blinking green "RN/FL" light. So, I'm figuring someone tried to flash it, and it didn't work. Any thoughs on how to fix this? Can I send firmware up to it through the serial port somehow? Thanks, Nick
