UPS Support

Does WD My Cloud support an uninterruptible power supply?

i.e., can it communicate with a UPS via USB port?

 What kind of support are you thinking of?

 You can certainly plug the power into a UPS.

The kind where it communicates with the UPS…

In the event of a power failure, it is generally a good idea to shut things down properly *before* the UPS battery runs out.

The My Cloud doesn’t support it, but the My Cloud EX does

Seems to be correct from what I have seen. 

I wonder why.  Seems to be a simple feature to implement, and My Cloud has a USB port. 

Would be a good feature to add.
