Main goal: To set up a Synology NAS in such a way that it will automatically shut down when it detects a loss in power / low power on the UPS.
From this support article, it sounds like this can be accomplished if I connect the UPS to the NAS via a USB cable. Looking on Amazon, I found this. But I have general uncertainty if I’m on the right path or not. Could someone confirm? Thanks for the help!
Look into cyber power ups. I have 3, one for each array, and one for my PC.
I don’t need 3, I bought one used it until the battery needed replacement, bought a second to have one for each array. Then changed my mind and wanted to return the 2nd one for a rack mounted one. Contacted Amazon, the second one I bought wasn’t returnable, so they refunded it and let me keep it and sent me the rack mounted one instead.
They have a very long runtime and work great with the NAS arrays. Their USB cable tells the array to shut down.
They condition power too and level out surges and dropouts. They come with a crazy warranty covering the UPS itself and all the equipment connected to them, and are in the neighborhood of $200-300.
It would depend on whether your UPS supports it and if that serial cable is the correct one for your UPS.
I use this UPS with my DS920+ and works fine. It came with the USB-USB cable needed.
