OPTI-UPS Value Series VS375C 375VA 225W 6 Outlets UPS - Retail Right off the bat, this post is indeed not to technically in depth - In relation to [this post] and the UPS battery backup device I purchased, I experienced some troubling and at first nerve-racking boot errors when needing to reboot the computer after installing the provided linux applications on CD with the UPS. 

I will tell you right away, I ended up getting it to administrate the UPS, but not after it copied my inittab file to inittab.dn* (forget the exact file name), and replaced inittab itself with run-level configuration that I would think would not work on Debian based system of any kind.

The new inittab does contain the path to the binaries to be run at boot, but why in inittab, I do not understand.

I needed to edit the new run-level file and remove the dnpowerd related variables, and copy it back over to inittab.  I did this while running in recovery mode, remounting the drive rw.

I then placed the applications referenced in the run level file, and placed them in /etc/rc.local.  I then starts a web server on port 9982 with a default login of admin and a password of 1234.

All important information is piped through /dev/console along with the http web interface.

You are able to change event variables, however you need a current windows controller application to change specifications like output watts, and other, more technical information.

The linux service is able to send out network broadcasts of power status, and SNMP connectivity to remote hosts.  It can also alert you by e-mail, or page you through a modem.
