If it stays in the blinky red state, it might be worth hooking it up to a machine with a static 192.168.0.x/255.255.255.0 IP, and seeing if it's in rescue mode at 192.168.0.2. I've unfortunately fallen victim to this once after a power outage. Since then, I've not had it happen again, but my ZD took the rescue FDISK procedure to bring it back online.
So far, I've been able to write it off as a one-time quirk, but the symptoms do resemble yours. I had the power to the building be cycled, which resulted in a hard shutdown to the ZD1100. Afterwards, it stayed in blinky red mode.
