Many thanks once again to those that responded to my original posting
(and my follow up message) with information about Network UPS Tools,
other Linux-based tools like rtcwake, and commercial UPS products.
We have quite a bit more evaluation and testing work to do before
a power fail protection

Many thanks to those that responded to my original posting with
information about Network UPS Tools and commercial UPS products.
In our planning a path forward to implement UPS-based power fail
protection, we have come across what appears to be an issue with
the state of the CentOS 6 machines

You didn't say what brand/model of UPS you are using so I can't be
specific. Check with the manufacturer of your UPS to see if they have

If we wanted to protect our CentOS systems from facility power failure
in a similar way, is there operating system or other standard support
that we might employ? Most of the Linux-based applications are not as
critical as the engineering applications on
Some of our largest systems run Windows because it supports engineering
