    Just hooked my new 2011 Mini Server up to my APC Back-UPS ES 750 and the APC unit won't stop clicking. It sounds like it is continually switching the battery backup off and on. It does this 2-3 times a minute. The unit was previously used on my PC for about a year with no troubles. It just started this since plugging the Mini into it. Nothing new has been added to the UPS other than the Mini. Any ideas?
    Thanks!

    My printer and scanner. They were plugged in when I used to use it on my PC however. It's clearly the Mini causing the problem, I just don't understand why. It certainly is not pulling more power than my old PC.

    Are the printer/scanner plugged into the "battery backup" side of the UPS or to the "surge protection only" side?

    I have a 2010 Mac mini connected to an APC UPS plus a backup drive, and it has no problems. I also have scanner and printer plugged into the UPS, but on the "surge only" side.

    The printer and scanner are plugged into the backup outlets and the mini is on the master outlet.
