Using WinNUT Client with ReadyNAS 312?
I have a new CyberPower UPS, which I have connected via USB to my RN312. It is all set up to shutdown the NAS using the "Auto" threshold, which I believe is 5 minutes of remaining run-time. I al...
It turns out the version I got was from an older "fork" on GitHub, and I needed to get the latest version here:
https://github.com/nutdotnet/WinNUT-Client?tab=readme-ov-file
I installed this one, and configured the communications window like this:
No login info required. I only put in the NAS IP address, and changed the UPS name. It connected immediately!
The only other important settings I changed were the Shutdown Options:
The default shutdown runtime was set to 120 seconds. If the NAS shuts down at 5 minutes remaining runtime, that will be a problem. I set the PC shutdown time to 6 minutes so it will shut down first. Without that load, the run time should jump way up, and the NAS will run a lot longer.
It looks like it's all working. I'm not sure I have the nerve to test it at the moment...
I hope this info helps others. I think this approach is WAY simpler than all the others I investigated.
When remotely monitoring a ReadyNAS with as UPS attached via NUT, the user name is monuser and the password is pass.
Note that the nice display you pictured is what you get when a UPS is directly attached to the PC, not when monitoring a remote UPS.
Actually, that display IS from the UPS via the NAS connected to my PC. The WinNUT Client gets the info on the UPS from the NAS, and produces that nice display, mimicking what a direct UPS to PC monitor program looks like.
It's all very slick, once I got the right version.
I noticed that the voltage and frequency "gauges" in the display were wrong, and clearly set for European grid parameters. To fix this for US power, you have to go to the "Calibration" tab in the Settings. I have mine configured as shown below:
Now, my "meter panel" looks like:
The only thing that is out of whack is that the output voltage is showing 136V, which is WAY too high. The front panel of the UPS reports 121Vac output. I'm not sure if the UPS is telling the NAS the wrong value, if the NAS is misinterpreting the info from the UPS, or if the WinNUT program is misinterpreting what it is getting from the NAS...
I'll report back if I find a fix.
Apparently there is a known bug in older versions of the NUT software that will result in reporting the wrong voltage. Synology NAS's can also produce the same error, presumably because everyone is getting their NUT server software from the same source. This would have to be fixed with a firmware update to the NAS.
Given that the 312 is an older box, I'm guessing that is unlikely to happen unless the same firmware is in use in newer hardware. I just checked, and it doesn't look like NetGear has any current NAS products.
