Both up now, this nightmare behind me. I will be evaluating what all happened here, and how to improve it.
Bascially it seems the power supply went out, and took the motherboard and NIC with it, I made the mistake of using the same nic initially which seemed to take out the new power supply, luckily not the new board and server. So with a swap of nics again (and the ensuing delays due to network configs), we are up.
