Package nut-2.6.2-2

NUT is a client/server uninterruptible power supply (UPS) monitoring system that permits the sharing of one (or more) UPS between several machines. The 'server' monitors the UPS and notifies the 'clients' when the UPS is on battery or has a low battery. If you have a serial UPS, you will need a USB-to-serial converter and OS X drivers for the converter. In this case, install the base "nut" package. If your UPS connects via a USB cable, install the "nut-usb" package. This covers most APC Back-UPS models, as well as MGE Ellipse, Comet, Nova, Evolution, and Protection Center units. Some Belkin models may be supported. Tripp Lite USB models that use usbhid-ups (especially ones with LCD in their name) should work, but the tripplite_usb driver currently cannot open entry-level Tripp Lite USB devices on Mac OS X. If you have a MGE UPS with a Network Management Card that supports the XML/HTTP protocol, then you will want the "nut-xml" package. The "newhidups" driver was renamed "usbhid-ups" after the 2.0.5 release. To graphically view the status of your UPSes, install the "nut-cgi" package.

You will need to read the documentation in /sw/share/doc/nut/docs to learn how to set up NUT to monitor your UPS and shut down your machine when the UPS battery is low. Note that some USB UPSes may already be supported by OS X, and the NUT drivers may have trouble interoperating.
