GS752TPv2 firmware failure, or hardware failure?

I picked up a used GS752TPv2 that was "tested, powers on."  That it does, but I get no connectivity on any ports.  I got into the serial console and logged what's happening.  With no connectivity, I can not tftp anything. I can send a binary over ymodem to it from the menu, but IDK what I need to do to either save it as one of the boot partitions, or what I need/could do.
