<div dir="ltr">Hi Phil,<div><br></div><div>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 <a href="https://www.sparkfun.com/products/11189">https://www.sparkfun.com/products/11189</a> 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.</div><div><br></div><div>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.</div><div><br></div><div>--Larry</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Jun 25, 2017 at 7:53 AM, Philip Rhoades <span dir="ltr"><<a href="mailto:phil@pricom.com.au" target="_blank">phil@pricom.com.au</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">People,<br>

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. Now, after not having to be concerned by those issues for some time - most of my little web sites have been on Digital Ocean or other suppliers VMs for a long time - I am shutting down my DO servers and bringing my sites in-house. However, now I need to be concerned about reliable power again so I have spent a bit of time looking at options and I don't understand why most of the UPS offerings available do not come standard with a LAN port? Why is this?<br>
<br>
Do people have suggestions about my options? I have two main machines - say 250-400W total and a few small devices inc a Billion router and some USB devices. It would be nice to have at say 5-10 minutes battery backup before sending shutdown messages to the Linux machines.<br>
<br>
Thanks,<br>
<br>
