Smart-UPS RT 3000 XL turns ouput power off

[Anonymous user]

Hello,

I'd like to understand the incident captured below. The UPS appears to have turned its own output power off but I can't identify why.

The battery was known to be defective, but this had been the case for several weeks; and there was no event logged regarding input power. I don't understand why the UPS did not continue providing power, since in spite of the faulty battery (which has since then been replaced), there was no recorded loss of input power.

Complete event log attached. NMC is running version 6.2.1.

Hi Thomas - 

It's likely that there was a very brief power event that the unit did not log. The Install/Uninstall alerts are being logged so quickly that the Network card likely couldn't keep up with everything the UPS was reporting. When you start seeing a unit constantly logging installed/uninstalled issues like this it is also possible that the batteries are overheating and causing erratic behavior. I would recommend replacing batteries as soon as you get a bad battery alert, and to disconnect them if you see this type of rapid fire installed/uninstalled errors.

If your UPS is in warranty you can contact your local tech support team for a replacement.

Thanks

Liam
