We've had a few power failures lately and our UPS has gone down, is there a way to set a TS1400D to automatically power back on after power failure?  I can't seem to find any info on this functionality.

It can indeed. I believe if you look over the UPS settings in that manual one of the options causes that behavior, UPS recovery I think.

On a technical level, when the device is connected to power it starts the bootloader which then checks the "Alarm_B (Minute Register)" of the RTC for certain "magic" values to decide whether to proceed with a normal boot or wait for the power button to be pressed. 

If you're running Debian you can set this manually:

modprobe i2c-dev
i2cset -y -f 0 0x32 0xB0 0x45


I thought so too, but the option is greyed out:  https://www.dropbox.com/scl/fi/oyjautxycvw8pubvypma9/2024-07-19_08-36-55.jpg?rlkey=ya4xl4xkewcqtfwaf1bjdnpck&dl=0  (https://www.dropbox.com/scl/fi/oyjautxycvw8pubvypma9/2024-07-19_08-36-55.jpg?rlkey=ya4xl4xkewcqtfwaf1bjdnpck&dl=0)

I have no clue about the UI component, but I was able to confirm the hardware will do it when that value is set.

It's likely Greyed out because you dont have a UPS Syncing to it.

More recent TeraStations have a 'power recovery' setting that works like this without UPS (OFF/ON/LAST STATE).

UPSes are a good idea, though, if you love your data. Flickery power can really ruin a unit's day.

I have always (20+ years) used UPS's on all my devices, especially NAS and servers.  The last UPS I bought had USB only for sync so that's why I never connected it to the NAS.  I found out yesterday that the UPS is failing so time to look for another one with a serial port...thanks all!  I'll try to remember to come back and post my final findings once the new UPS is installed.

I think for TS1400D you'd need a UPS with USB rather than Serial. Might even be able to test that part with the failing one I suppose.

No serial port on the TS1400D, but there is what appears to be a dedicated USB port (it's a standard white instead of the blue super speed port)...however I got the new UPS in today, connected and that option is still greyed out.
