Check to see if apcupsd supports your operating system (see Supported Operating Systems ). Plan your configuration type (see Choosing a Configuration
Type ). If you have just one UPS and
one computer, this is easy. If you have more than one machine being
served by the same UPS, or more than one UPS supplying power to
computers that are on the same local network, you have more choices
to make.
