I have a APC 600VA UPS I got to use for a mac mini running as a server and a NAS drive. The plan was to run a QNAP NAS for storage and media, then have an extra mac mini I have run as a server. Mostly just to play with, but maybe use as a backup server or an email server when I learn more about it. It's just to play with. The thing is the APC UPS has a USB port to shutdown the mac mini and the QNAP can also use this. Is it possible to split the USB port so both the Qnap and the mac mini get connected to the UPS? I have one UPS for my main desktop, and one for the NAS. A third for the mini server isn't in the cards, I'd like to run the NAS and the mini server off a single UPS. I don't think there is power chute software for macs.
