I was tweaking the UPS rules at a client’s site, when I noticed that the base NUT configuration that we use didn’t really do a hell of a lot. The example config files had some hints as to what were needed, but unless I missed something fundamental, didn’t have the full picture.
After a bit of searching, my laptop battery ran out so I couldn’t carry on working onsite. I did get far enough to make some notes, but I have since lost the site I referred to, so can’t put proper attribution. It looked something like this one though, and was also dedicated to setting up NUT on a Mac, so I figure that will do.
I’ve since returned to this issue, and after fighting with serial and USB cables, have finally completed and tested it all. My configuration is on the WLUG wiki at the NutNotes page.
