[GLLUG] UPS for Linux Boxes

[John Lewis]

I have an APC SU-1250 which the battery packs have gone flat. APC tells me
the fix is to return them to APC and buy a new unit, which is not an option
for me. Does anyone have a cost effective source for replacement packs for
this thing?

When I had my hosting company, we used rack mount UPS's for a lot of Sun, HP
and IBM gear. They were SNMP enabled and software that could communicate
with the server(s) that were attached to them. This was not so much for
operations to monitor the UPS as it was for the UPS to trigger a clean
shut-down of the server if the UPS power reserve dropped to an unsafe level
that risked sudden power loss to the server.

APS makes several that include software for Linux. I have included model
numbers below.

All of these UPSs include a software CD with PowerChute plus for Linux (as
well other legacy operating systems such as Windows XP). The software is
easily installed. It has a really nice GUI that allows you full control over
the UPS. You can set audible alarms, paging, email alerts, broadcast power
events, run command files, etc., based on trigger events. Complete control
over logging is also included.

Each UPS includes a serial cable which connects to one computer. If you have
more than one computer connected to the UPS you have a few options. The
first and recommended option is to buy the Web/SNMP card described above. It
essentially turns your UPS into a mini server, where it communicates over
ethernet directly with each UPS.

Another option is to have the UPS hooked up to one computer via serial port.
The UPS then tells the computer via serial port that there is a power
problem, and the computer then tells the other computers over the ethernet
about the power problem. Unfortunately, APC's software doesn't support this.
It can be done using the Open Source software described below.

There are two main options. One is apcupsd (http://www.apcupsd.org/). The
other is Network UPS tools (http://www.exploits.org/nut). Both are really
nice, and have all sorts of features, including web reporting tools.
