Folks,

I have the following UPS:
G1000U
http://www.tripplite.com/en/products/Specialty-Products.cfm?ID=4164

I bought it about a month ago and noticed about once or twice a week I would come home and both it and my Mac Pro were powered off. Confirmed 'Improper Shutdown' in the logs.

Thinking it was a bad UPS, I exchanged it from Costco. I then had it working for about a week without the USB control cable plugged in without issue. The day after I plugged the USB to the Mac, I came home and they were off.

I have since left it unplugged from the USB cable for 2 days with no issues.

Has anyone seen anything like this? I would expected possibly if there were a setting issue, my machine would be off because of a shutdown initated by the settings, but not both the machine and the UPS.

Thanks!
