My UPS is connected by USB cable to my readynas RN104. I regularly get the message: Error communicating with UPS UPS (). Then I usually get a message shortly after: Communication with UPS UPS () is OK. This happens several times a week. Im using version 6.5.0 but also had this issue on previous versions. I have tried using different usb ports on the Readynas.
My UPS is Manufacturer: APC, Model: Back-UPS ES 600G,
An example of the log entries I see are:
Tue May 24 2016 4:19:15
System: Communication with UPS 'UPS' () is OK.
Tue May 24 2016 4:19:06
System: Error communicating with UPS 'UPS' ().
Any suggestions on how to fix this? Thanks.
Model: RN10400|ReadyNAS 100 Series 4- Bay (Diskless)
Hi Brian - I have tried a different USB cable and tried using different USB ports on the readynas and I get the same result. I've plugged the UPS into a laptop and the APC Powerchute does not find any issues with the UPS. Unfortunately, I do not have another UPS to try. What is the best way to send you the logs? I'm not sure I want to post them publicly (not sure if they contain private or sensitive data).
Here's the article on how to send the logs to NETGEAR. For now, isolating the problem is what we can do since not all UPS devices are supported by the system. Give us ample time to check on your logs and see what we can find.
Thanks for the update. I just resent the logs. I hope they help. I have not connected the UPS to my PC (or another device) yet. I haven't found a maintenance window yet where I can bring down the NAS and the router and switch that are connected to it. That would bring down the whole network. Let's see if the logs provide any insight.

You don't need to change your power connections. All you really need to do is move the USB connection - which won't bring down anything.
Thanks. That's a good idea. I'm going to have to find a laptop I can put near the UPS and NAS. They are in a separate area from my desktop. Any insight from the logs?
I do have a USB disk connected also. I use that for backups. I disconnected it for 12 hours for a test. Only the UPS was plugged in to a USB port on the NAS. The UPS still disconnected and reconnected itself 3 times durning that period. (I don't know if this is related, but the USB disk will disconnect itself, but that only happens every couple weeks).
I have been running with the disk spin down feature disabled for several days now. I have not had the ups disconnection error during this time. I have had the USB disk disconnect though. How do I get both of the USB devices to stay connected while I am using the spin down feature?
