Having said that, higher end gear appears far more likely to have a LAN port or capability thereof . . . the cheap hope stuff does not, considering that it likely would not see much use. In any case, NUT server mode pretty well negates any need . . . at least in my experience . . .<br><br><div class="gmail_quote">On June 25, 2017 7:53:08 AM CDT, Philip Rhoades <phil@pricom.com.au> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
<pre class="k9mail">People,<br /><br />A couple of decades before I was retired and was still working for other <br />people I had cause to install UPSs and they usually had RS232 ports to <br />allow the setting up of shutdown scripts to UNIX / Linux servers. Now, <br />after not having to be concerned by those issues for some time - most of <br />my little web sites have been on Digital Ocean or other suppliers VMs <br />for a long time - I am shutting down my DO servers and bringing my sites <br />in-house. However, now I need to be concerned about reliable power <br />again so I have spent a bit of time looking at options and I don't <br />understand why most of the UPS offerings available do not come standard <br />with a LAN port? Why is this?<br /><br />Do people have suggestions about my options? I have two main machines - <br />say 250-400W total and a few small devices inc a Billion router and some <br />USB devices. It would be nice to have at say 5-10 minutes battery <br />backup before sending shutdown messages to the Linux machines.<br /><br />Thanks,<br /><br />Phil.</pre></blockquote></div><br>
