UPS connected to TNAS get crazy

Post by Cafsenra »

Hi, I had connect my UPS APC CS-500 to TNAS, however since I updated to TOS version 4.2.15 I started to get errors on my UPS turning on yellow light. These problems disappear when I disconnect the UPS from TNAS. My guess is that something is wrong on TNAS side who is not recognizing UPS making some kind of requests by usb that leaves to this UPS behavior. You have any clue of what might be happening?

Hi,
Was there a power outage at that time?
Some UPSs have a yellow indicator light when there is no mains power supply and power is provided for other equipment.
Or was there a power outage before the yellow light turned on?
If the battery has reached its end of life, it may also light up yellow.
You may be able to find the right answer with UPS sales customer service, they know better about UPS.

Hi TMRyan,

Thank you for your reply.
As I explained, the issue was solved immediately when I disconnect USB connection TNAS to UPS.
There wasn’t a power outage.
And the devices remain with power.
I believe that might be a issue with driver for UPS used by TOS.
