If I use shutdown instead of hibernate in the Windows Power Options, then when I pull power from the UPS and the battery hits my set critical level the DX4000 seems to power off very quickly and when I power it back on it has to go through the process of verifying the RAID. Whereas if I shutdown normally through the dashboard it takes a little time and the display on the front of the unit says “SHUTTING DOWN”.
It seems like some other users were running into the same issues with shutdown being triggered by an UPS as well, it was mentioned in this post: DX4000 on UPS - #7 by Gramps
