Debugging erroneous UPS alerts
We just moved out RN516 from our main computer room to another building and its now on its own UPS (Tripp-Lite Omni1500LCDT). The UPS is connected via USB and when viewing the UPS status in the ReadyNAS admin console it is recognized and the status is showing up correctly. I did some initial testing by unplugging the UPS from building power and I immediately received an alert email from the ReadyNAS stating the UPS was now on battery power. After 5 minutes I plugged the UPS back in and immediately got another alert stating the UPS was back online with line power. All was good.
The next morning around 5:00am I received an email from ReadyNAS stating "UPS battery is low. System is going to shutdown soon." It did not shut down. I received two more of these messages the next night. I've opened up a case with Netgear support on this, but they are saying it may be a compatibility issue with the interpretation of the codes it is receiving from the UPS and to wait for a future firmware update. So I need to troubleshoot this further and asked if there was any way to retrieve the actual code(s) the UPS was sending that triggered these messages. No love.
I also contacted Tripp-Lite support and asked them if the unit should be generating ANY messages as long as the unit is on building power and nothing else changes. They said no. So my question for the group is the same one I asked support - is there any known way to retrieve the actual codes being send by the UPS, or has anyone experienced similar behavior from a USB connected UPS? If the UPS is indeed the culprit I want to get it replaced (its only a week old).
Thanks,
Dave

Just a thought ... could interference on the mains cause the battery low messages?
That seems unlikely, since the UPS is supposed to clean up the mains if needed.BaJohn wrote: ...The 'battery low' messages keep happening, but this is the first time L have seen the 'Error communicating' message.

Do you have a different cable you can try?
It might be worth monitoring on a PC for a day or so, possibly something is wrong with the UPS.
It does clean up the mains, BUT if I get a break of 0.5 second, is that going to cause the original messages. Literally 30 mins ago, I was on my PC and the lights flickered and I got a 2 verbal messages from my PC UPS and on checking my NAS the logs hadStephenB wrote:

The TV went off for a split second as well, as I checked with 'the others' in the lounge. That I believe was a genuine 1 to 2 sec mains break, but the previous messages seem to be spurious and random in occurrence.

Are you talking about the UPS to NAS cable? That is a special cable that came with the UPS. No spare although I suppose I could find a replacement somewhere online.StephenB wrote: Do you have a different cable you can try?.
Having had the 2 second mains break a little while ago, I am reluctant right now to do that. Maybe after my holiday. Anyway, am currently trying to fix my washing machine before we go away which the wife says takes priority.StephenB wrote: It might be worth monitoring on a PC for a day or so, possibly something is wrong with the UPS.
The originator of this post (not me) said something about waiting for next update of OS. Does he know anything more about the problem.
I am also not the only one having this problem. Also I sent my logs as requested and have had no response to that. Hopefully those 2 options of a possible helpful outcome are still open?- My cyberlink uses a normal USB cable, so that is easier to swap out. The custom serial-USB cables can be hard to find and pricey.
I was thinking that you could leave the UPS connected to the NAS, just switch the monitoring for a bit. Then the NAS is still protected from those short outages (which I agree is important). It wouldn't receive shut down messages, but it sounds like your outages are much shorter than the battery limit.
A good idea BUT my PC is through 4 doors away from the NAS. You forgot I can't get a good WiFi speed between the two, owing to the distance and thick walls (another post). BUT, a great idea, as I can get (hopefully) my old Vista laptop working (after my holiday ... boring I know to mention it again) and give that a go.
