Controlled outlets going on and off on Backup UPS 1080

This was originally posted on APC forums on 11/4/2014


I have a  Backup UPS NS 1080. There is some strange behavior with the controlled outlets since I have upgraded to Mac OSX Yosemite. I have set the threshold repeatedly (twice with the tutelage of APC support folks on the phone). The second time we plugged a floor lamp into the controlled outlet and it went on and off repeatedly after we set the threshold. I have set the threshold both with the computer (a late 2013 iMac)  asleep and turned off. Yet, nothing seems to work. APC thought perhaps the unit was faulty and replaced it, but the problem persists with the new unit... computer asleep and the controlled outlet(s) are going on and off. Only a problem because I have the computer speakers plugged into one of the controlled outlets and I can hear the subwoofer loudly "pop" when it turns on and off while the computer is asleep... a pain.

Any ideas how to resolve this?

Thanks.

Hi,

Do the outlets switch on and off when the Mac is powered off or just when in sleep mode? Also, is the Mac connected to the UPS via USB?

If the outlets stay off while the Mac is off then a temporary solution is to power the Mac down while not in use and or power down the speakers while not being use to prevent the popping.
