I have plugged my APC UPS into the USB Port.
I want to wait 10 minutes after power loss before shutting down to be safe.
The UPS should run on battery for at least 30 minutes,
The UPS is recognised and correctly identified as can be seen in the image below.
The estimated use time remaining reads "Use time predictions unavailable"; Is this normal?

I have checked Enable USB Support
I have selected USB UPS as the device type
I have selected 10 minutes as the runtime.
I do not want to set up a server, so I have not checked Enable TNAS UPS Server , and so the IP entry is not usable.

When I click apply, I see a connection failed message asking for an IP address; I have not and should not need to enter an IP address.

I don't know if this is a fault, or if I am misunderstanding the instructions.

Could you please specify which version of TOS 7 you are currently using? Also, what is your NAS model?
The remaining time is based on data reported by the UPS. Your UPS model may not support this feature or may be unable to accurately estimate the remaining time.
The “Connection Failed” message you mentioned may be a UI error. We will investigate this issue.

The Current Version is 7.0.0804
The UPS is a APC Back UPS - BX750MI
The NAS is an F2-425 Plus

Thank you for the additional information. Any further updates will be posted here.

Hi.
Regarding the issue you mentioned, we have decided to optimize or even redesign the UPS module in future versions. Please look forward to future TOS updates.
