Setup and installation was pretty standard. The only hiccup was I had to

Did you install via the official .debs, or source? The Ubuntu .debs should set
everything up with udev - if not, please file a bug:

Ubuntu repos. I may file a bug, but come to think of it, I wonder if
its was because I plugged in the UPS before installing the
packages...and thus the udev rule didn't fire.
Does it re-trigger all the rules after an install of the nut package?
As Doug mentioned, by default NUT shuts down when the UPS signals LB (low battery). If
there is no "upsrw" variable available to adjust, it means one of two things:
the UPS can't adjust this limit, or we don't know how to adjust it. [update: I see that
this is not listed in the upsrw output. bummer.]
It is worth pointing out that the serial and non-PDC Tripp-Lite UPSes are all
based on reverse-engineered protocols. Only the Tripp-Lite models supported by
usbhid-ups are based on an open standard protocol (HID Power Device Class), and
even then, some experimentation was needed.
Given the sorry state of the "PowerAlert" software from Tripp-Lite, I am
very grateful to those who created this driver.
