ReadyNAS Ultra 6 doesn't boot - Stuck on "ReadyNAS" prompt screen
Hello everyone
I have exact same symptoms as the thread "ReadyNAS Ultra 6 doesn't boot - Stuck on ReadyNAS prompt screen"
I took (and lightened) the message of this post
sorry for me english !
I have upgraded my old ReadyNAS Ultra 6 to OS6, from 4.2.
I replaced the 1GB RAM in the unit with 2x1GB sticks, and followed the upgrade process (BIOS_Update_Package_0.5-x86.bin, PREP4TOR6_0.1-x86.bin, R4toR6_6.9.5.bin), and all seemed good.
6x2TB disks : resync OK.
All seemed OK, I then did the auto-update to the last firmware version : restart ...all was OK.
Attempted to power the NAS back on - it now just says "ReadyNAS" on the front panel, and won't do anything else. Holding down the reset switch does not bring up any boot menu. I have pulled all the disks, no change. I swapped the memory back to the original 1GB, no change.
Tried to downgrade firmware to 4.2 and to reset the unit (no data) with the switch
Thanks in advance for any help you can give me.

This looks like a power supply issue - unfortunate timing, but perhaps linked to the extra load of rebuilding the RAID array. Perhaps Sandshark will confirm.
The PSU is something you can replace.
The unit will say "ReadyNAS" with nothing except the 5V from the PSU. That means the processor doesn't even need to be running. So the first thing to check is that you fully inserted the memory. Then try with just one DIMM, and then the other, in case one is bad. If that's not it, then the PSU is a likely candidate. If you have a standard ATXV12 computer PSU available to test with, you can connect it externally to see if a new PSU will fix the problem. I recommend doing the testing without the drives until you get to the point the NAS complains of "No disks". Then, install your drives with power off and I expect all will be well when you power up. If you don't have a PSU to test with, the SFX format supply needed for the NAS is pretty inexpensive. Though the original is rated at 300W, I recommend at least a 350W replacement because the original can deliver more +12V than typical 300W supplies. You can also use that supply externally to see if it's the right fix before you go through the trouble of installing it internally.
A standard SFX supply needs a couple adapter/extender cables to work. You can find units on eBay that are already modified for use with a ReadyNAS, though you'll pay a little more.
