Thanks for the info. From what I coudl gather about NUT the implementaion
involves a UPS connected directly to the system via a serial interface and
the system functions as a server that then sends out commands to other
systems running NUT 'clients'. Will it work with the APC WEB/SNMP Card?

I have been using the snmp drivers with Network Ups Tools (NUT), an
project, and although still tweaking the configuration, it seems to be
good. I have used older versions of Powerchute on assorted *nix boxes, and
while it more or less worked, I am intrigued with NUT for the following
1) open source, so do not have licensing issues preventing keeping the same
version of the software on multiple UPS/CPUs. Also, somewhat less
with ensuring support for older OS/OS versions. And more transparent as to
what is actually happening, e.g. what it actually calls to shudown the
2) Although I am not that familiar with the latest Powerchute versions, I
talk to an APC representative about a year ago at a trade show, and I
Powerchute was rather limitted in dealing with either a single UPS supplying
multiple boxes, or a box with multiple power supplies each fed from a
UPS. NUT does not deal with this perfectly either, but have at least
to consider the issue to a much greater depth.
3) NUT has better command line support, which assists with scripting and
integrating with other systems (e.g. Nagios, MRTG). Powerchute, as I
it, was all or mostly GUI, and has probably continued in that vein.
4) Although we are pretty much an all APC shop wrt UPSes, NUT supports
vendor UPSes and having that freedom is nice.
There also is an apcupsd project.
Anyhow, I cannot offer assistance with Powerchute, but if you continue to
problems, you may want to look at NUT.
