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

- I am only a Newbie to ReadyNAS, but have already raised a post about the lack of UPS information flowing to the NAS.http://www.readynas.com/forum/viewtopic.php?f=24&t=79444
I believe that a PC connected to the UPS will be able to obtain far more information including logs.
If the 'problem' is regular and you can sensibly do it, I suggest that you power a PC from it and then run for a few days.
If that gives no joy, somewhere in this forum I have seen a post on how to connect a PC as well as the ReadyNAS to the UPS.
If neither of these is possible, I have no other ideas. - UPDATE:
After a few more of the erroneous "UPS battery is low" messages, the ReadyNAS simply dropped the UPS from the list of monitored UPS devices. I then hooked up a stand-alone PC with TrippLite's UPS monitoring software to see if it could pick up any additional info. I kept the PC hooked up for two weeks and reviewed the logs generated by the TrippLite monitoring software. Nothing out of the ordinary, everything looked normal. I removed the PC and plugged the USB cable back into the ReadyNAS and the erroneous errors started showing up again and the UPC was dropped again after a few days.
At this point I guess the only thing to do is wait for Netgear to provide a fix via a new firmware update. - Can you send me your logs (see the Sending Logs link in my sig)?
I have had the intermittent "UPS battery is low" for a little while. I put it down to building works in the house potentially affecting the supply (power drills etc). Anyway, I upgraded to OS 6.2.3 on Thursday 23rd April and went away for the weekend. This morning, at first look, low and behold I to have the problem.dcline97 wrote: After a few more of the erroneous "UPS battery is low" messages, the ReadyNAS simply dropped the UPS from the list of monitored UPS devices.

Since this was going on for some while, MAYBE just maybe something was introduced at OS 6.2.3 to generate the 'removal'. This does not of course help with the underlying problem.
Would you like my logs as well?- Yes, please send me your logs (see the Sending Logs link in my sig).
- Logs sent.
- Can you connect the UPS to the front USB port (just for testing) and see if it behaves any differently?
Sorry too late, as I tested whether a re-boot would 'fix' (albeit temporarily) it, and yes, after a 'restart' from NAS admin page the UPS connects back again.mdgm wrote: Can you connect the UPS to the front USB port (just for testing) and see if it behaves any differently?
When (presumably) it disconnects as can be expected from other postee, I will try what you suggested.
Swapped the connection from back to front earlier today and have had 2 of the messages already. So no, it is no different using the front USB port.BaJohn wrote:

It was around 1 day ago and during that time 2 messages came up. This morning I swapped the USB cable from front to back, and almost immediately the UPS was removed from the port with message:-BaJohn wrote: Swapped the connection from back to front earlier today and have had 2 of the messages already.

NOTE that on a subsequent reboot the UPS was re-connected.
