The following video is the result of a test between the Synology NAS DS1513+ connected to a APC BR900GI UPS. Both devices brand new, the Synology was configured through DSM 4.3 - Control Panel - Hardware the following way:
General: - Power Recovery: Restart Automatically after a power failure.
UPS: Enable UPS Support (checked). Time before DiskStation enters safe mode (10 seconds). Shutdown UPS When system enters Safe Mode (checked).
Logically this 10 second configuration is for the sake of the test :)
As you can see for some reason the beginning works without any problem, when I re plug the UPS everything seems to start working again, but for some reason the NAS abruptly shuts down itself again without ever touching the power cable from the outlet.
UPDATE: I think I found why this error was happening. Maybe the self test of the UPS every time it starts up again was producing this to the Synology NAS. I tested a shutdown programmed after 10 minutes of power loss (instead of 10 seconds as I initially tested) and everything worked as expected. I will continue with my testing, anyways if anybody wants to share their point of view of the situation would be great! Thanks!
