But if I had a UPS for my home box, and the power went out, and the UPS went to work for a short period of time, how would my system know to "init 0" or something like that during the time the UPS would be able to feed it?
First, you need one that has some time of communication port with the computer. The old type just had some contacts, that were plugged into some of the auxiliary control lines of a serial port, and this way, the status of "online, on batt, or batt nearly depleted" can be communicated to the computer. Then, there are better types with an ethernet, usb port, or real serial port, and contain some kind of microprocessor. And some of them can be controlled by linux, using the package "nut", or sometimes, a proprietary package of the maker. Bad news is that they can cost almost double the price of a plain UPS. - -- Cheers, Carlos E.
