I've got an Eaton UPS, connected to my QNAP NAS. Whenever it detects a power outage, it will tell the NAS, and it will shutdown after 5 minutes.

However it randomly happens that it detects a power outage, but there is no outage at all. The issue is, that it then only tells the NAS there's an outage. Probably because it goes so fast, it doesn't tell the NAS the power is back.

I've asked Eaton, they say this may happen during a power surge.

Should I buy a new UPS? Or is there a way around this?

can you not have the NAS check the battery capacity of the UPS and shutdown when it gets less than 50% or something?

if the UPS is older it may not allow that though

Good suggestion, but don't think my QNAP supports that.

Ive got a QNAP and an eaton UPS,

On mine there is an option to shut the NAS down after X minutes of power failing.

Model or Specs?

Load Pwr Spec?

Config?

Makes not much sense to ask for a way around "something" without minimum information about "something."

Maybe you need a small UPS to supply better power to your main UPS? ;)

I think I fixed it for now :) I've attached the UPS to a linux server, and made that one master, and then the NAS made slave.

Used this package: https://networkupstools.org/

Will monitor this, but so far looks good.
