New user. What a great resource. I just set up a DS920+ and when I plug in the UPS it immediately goes into battery mode and starts beeping. When I unplug the usb cable the nas front panel shifts to the red low battery indicator with a steady tone. I turned off the NAS and turned off the ups and the red light came on. the only way to stop it was to remove the battery interlock. Re connected and restarted the NAS and all is fine without the USB connection. Its an older USB with new batteries so that may be the issue. It's definitely communicating with the NAS because the effect is instant when the usb cable is plugged in. It also doesn't register in the NAS area of the hardware and power section. Has anyone seen this behavior before? Thanks,
Mark
