RN31400 Powers off within seconds off pluggin it in.
My RN314 ( 4 10tb drives ) was off when I got back to my home office. I pressed te power button but nothing happened. I suspected the power supply but the green led was lit so i tried my spare PS. Same result power off wthin seconds of plugging ps in to the unit and pressing the power button does nothing.
I then removed all 4 drives and tried again. Same result. Welcome msg appears then power off. If I try hitting the power button nothing hapens.
I then removed the network cables so there are no drives or network cables but the same issue. I do not hear the fan start up could it be a fan failure?

It could still be a power issue (there is still power circuitry within the chassis). Did you look closely at the power socket on the chassis? Sometimes it gets damaged over time. But it could also be another component failure (memory, CPU, etc).
I don't think the fan would cause this particular symptom - @Sandshark might know.

I'm not aware of any ReadyNAS shutting down immediately because of a fan issue. The CPU would eventually overheat and it would shut down, but that should take longer.
So the unit comes on if you disconnect and re-connect the power, but not when you press the power button? That sounds like a problem with one of the internal power regulators, probably the 3.3VSB which powers the NIC and power on/off circuit. Something in the NAS likely is overheating, but not due to the fan not working. Again, that would take a while. Without a schematic, there's nothing to be done about that, I'm afraid.
The standby power is on all the time, even when the NAS is off. If you have ever allowed the unit to get hot, even when "off", that can cause problems. But since it is on all the time, it's also the one most likely to fail for any other reason.
If you unplug it and leave it unplugged longer, does it lengthen the time before it shuts down? If it does, then the 3.3VSB is an even more likely cause.

I talked with tech support and they think the firmware in the box got corrupted somehow. Unfortunately I am on a sales trip until next week so I can't try their suggestion of applying power to the unit with the drives out and the reset held in to see if the boot menu comes up. I will try that this coming week when I return to my home office.
Good suggestion to see if it stay running longer if I have it unplugged for a much longer time. Since I am away its completely un-plugged and powered off for at least 6 days. I hope that shows something.
Tech support tells me the chassis is still under replacement warranty at the moment. So that might be good news. I just hope I see something from the boot menu or trying the boot from USB.
