This is false. All hardware revisions of DNS-321 have the hardware to support auto-power recovery. We only added the option in 1.03 firmware. There is NO configuration for it. Test it out, turn on your 321 and let it boot up. Pull the power plug from the wall. Plug it back in ater a few seconds, did it turn back on? Feature is working as intended.
Not true. I just tested this and my NAS unit did not turn back on. I am running firmware version 1.03, Hardware Rev A2. I unplugged the power from the electrical outlet for 30 seconds and plugged it back in. The only light on is the power supply (brick) green led. The NAS remained off. The drives were in hibernate because I didn't want to pull the power while the NAS was writting to the drives.
[Edit] I was able to get the NAS to power down and reboot
ONLY if I pulled the electrical connector from the back of the NAS, not the power cord out of the wall. There must be something going on betwen the power supply and NAS electronics. So long as I pull the power supply connector from the back of the NAS first, I can do anything like unplug the power supply from the wall, wait a few second and plug the NAS in, then plug back into the wall and it powers up. I believe the electronics when the power is severed (both 5 & 12 VDC) together it works but I'll bet that when you unplug the power supply from the wall that the 5 and 12 VDC drop differently causing the discrepancy. So this feature is not helpful to me since I doubt I'll be pulling that connector to simulate a power failure. And this is fully repeatable.
