[USR-TC] NMC Code update failure

Hi. I attempted to update the operational code to 7.1.8 on several of our NMC NACs recently, using TCM 7.0.7. Some worked fine. On two of them, the TFTP transfer failed before it completed, and the cards were left codeless. When I reconnected to them to try again, the transfer failed. I can no longer connect to them through the TCM, presumably because the IP is gone. The console too is silent when I try it. What do I need to do to get firmware back on these cards?
