Hi Phil, I don't have an answer to your question about the lack of LAN ports, but can offer my experience with NUT for a home server environment. I've tended to prefer the Tripp-Lite UPS systems, mainly because I originally felt they did a good job of power filtering. I use a NUT master running on a Raspberry Pi 3 which is easy to maintain and gets current updates via its Debian roots. I have two environments, one with a much older UPS which has only serial, but the addition of a tiny card with a MAX3232 level-shifter https://www.sparkfun.com/products/11189 allows the RPi to communicate nicely, the second environment uses a USB connection from the RPi to the UPS. Both work very well with NUT, and then communicate with NUT clients on the other systems. I like that the RPi allows me to separate the NUT master function from the main virtualization hosts, currently CentOS/KVM in this case.
The real key is to ensure NUT supports the UPS, and then from there an effort to use currently supported versions of NUT on a platform which is receiving updates & life is quite good. --Larry On Sun, Jun 25, 2017 at 7:53 AM, Philip Rhoades <p...@pricom.com.au> wrote: > People, > > A couple of decades before I was retired and was still working for other > people I had cause to install UPSs and they usually had RS232 ports to > allow the setting up of shutdown scripts to UNIX / Linux servers.
