Just to be clear the PT or Power supply is connected the APC UPS? I don't see how the power supply being connected to a UPS would cause that.crazydane wrote: ↑Wed Mar 10, 2021 11:08 amI'm pretty sure I figured out the issue. I took a closer look at the receptacle that is powering the 1240 (and Etherport) and traced the feeder back to a UPS...
Took a look at the UPS logs and sure enough:
So once the input voltage reaches a certain value, it "compensates for a high input voltage". I modified the config to allow the output to rise to 135 volts (was set to 127 volts), so that should address the issue.
Sorry to have taken us on a wild goose chase on this one!

It's an ECM-1240 so the power supply is also the PT.Teken wrote: ↑Thu Mar 11, 2021 1:48 pmJust to be clear the PT or Power supply is connected the APC UPS?
