Problem booting ReadyNAS NV after IP address change to DHCP

I have a ReadyNAS NV that has been running fine. However, I today changed from a hard coded IP address on an old subnet, to DHCP. It gave me a warning about not being able to access when the IP changes. I have tried both the old address, nothing there? My DHCP server has not handed out a new address for the ReadyNAS either.

Now I cannot access the box, and when it boots, it goes through the boot process, and the power light stays on steady blue. However, there is no disk or network activity light. I think this means it booted OK, but cannot connect to tell.

I am sniffing the ethernet cable right off the NV, and there is NOTHING coming off the box, no ARP, no DHCP requests, no broadcasts of any kind!!! Very Odd.

I have tried the USB boot, but it gave the blinking pattern that the firmware that says:
"RAIDiator image does not match NAS platform, contact tech support to convert OEM NAS to ReadyNAS."

Please advise how I can get the network access back up to my box. I have power cycled it a few times, and it still ends up in the same state.
