col) UPS equipment
NOTE
This man page only documents the hardware-specific fea-
tures of the bestups driver. For information about the
core driver, see nutupsdrv(8).
SUPPORTED HARDWAREbestups was designed to monitor Best Power UPS hardware
like the Fortress, Fortress Telecom, and Patriot Pro. It
also recognizes and supports SOLA units such as the 520
and 620.
Other UPS hardware using the Phoenixtec protocol should
also work, but they will generate a warning since their
battery information is not known.
This driver does not support some older Best/SOLA units.
Try the bestfort driver if this one does not detect your
UPS.
EXTRA ARGUMENTS
This driver does not support any extra settings in the
ups.conf(5).
BUGS
The battery percentage is derived from the voltage data
that the UPS returns, since the UPS doesn't return that
value directly. On some hardware, the charge will remain
at 100% for a long time and then drops quickly shortly
before the battery runs out. You can confirm from the
BATTVOLT readings that this is a problem with the UPS and
not this driver.
Similarly, the float from the charger in some models
forces the battery charge percentage back up to 100% imme-
dately after the UPS goes back on-line, so you can't tell
when it is really recharged.
Finally, some models give one value for the battery's nom-
inal voltage and yet actually have a nominal voltage
slightly below that. This leads to things such as the
perpetual 98.7% charge on the author's Fortress 750, even
when it's been charging for weeks.
