It does look like the common way of doing this is to have one NAS with the USB connection as a primary (Network UPS Server) and then use one of a variety of tools to set the new NAS as a slave to it. But this relies on the network being available - which in your case you won't have. <br /> <br /> I suppose it depends on whether the UPS does some sort of pairing via USB and only allows one pair.</div> <div class="message_footer"> <div class="message_footer_links"><a href="lpost.php?webtag=DEFAULT&reply_to=42710.9&return_msg=42710.8" class="reply"><span class="image post"></span>Reply</a></div> <div class="message_vote_form" data-msg="42710.9"> <span class="rating">0/0</span> <span class="image vote vote_down vote_down_off" title="Vote Down"></span> <span class="image vote vote_up vote_up_off" title="Vote Up"></span> </div> </div> </div><a name="a42710_10"></a><div class="message" id="message_42710_10"> <div class="message_header"> <div class="message_from"> From: Matt<span class="message_time"> 4 Dec 2020 13:07</span> <div class="clearer"></div> </div><div class="message_to">To: koswix <span><span class="image post_read" title="Read: 5 Dec 2020 19:55"></span></span> <span class="message_count">10 of 19</span><div class="clearer"></div> </div> </div> <div class="message_links"> <a href="lmessages.php?webtag=DEFAULT&msg=42710.10">42710.10</a> In reply to <a href="lmessages.php?webtag=DEFAULT&msg=42710.8#a42710_8" target="_self">42710.8</a></div> <div class="message_body"> This.<br /> <br /> In my experience, the UPS will be a downstream device (think printer, thumbstick, etc.) and you will optionally have some software (usually built into the OS) that detects the change in power source from the UPS and displays that to the user or logged somewhere.<br /> <br /> It's unlikely to work the other way around.</div> <div class="message_footer"> <div class="message_footer_links"><a href="lpost.php?webtag=DEFAULT&reply_to=42710.10&return_msg=42710.8" class="reply"><span class="image post"></span>Reply</a></div> <div class="message_vote_form" data-msg="42710.10"> <span class="rating">0/0</span> <span class="image vote vote_down vote_down_off" title="Vote Down"></span> <span class="image vote vote_up vote_up_off" title="Vote Up"></span> </div> </div> </div><a name="a42710_11"></a><div class="message" id="message_42710_11"> <div class="message_header"> <div class="message_from"> From: ANT_THOMAS<span class="message_time"> 4 Dec 2020 18:24</span> <div class="clearer"></div> </div><div class="message_to">To: Matt <span><span class="image post_read" title="Read: 6 Dec 2020 19:54"></span></span> <span class="message_count">11 of 19</span><div class="clearer"></div> </div> </div> <div class="message_links"> <a href="lmessages.php?webtag=DEFAULT&msg=42710.11">42710.11</a> In reply to <a href="lmessages.php?webtag=DEFAULT&msg=42710.8#a42710_10" target="_self">42710.10</a></div> <div class="message_body"> Glad I'm not going crazy.</div> <div class="message_footer"> <div class="message_footer_links"><a href="lpost.php?webtag=DEFAULT&reply_to=42710.11&return_msg=42710.8" class="reply"><span class="image post"></span>Reply</a></div> <div class="message_vote_form" data-msg="42710.11"> <span class="rating">0/0</span> <span class="image vote vote_down vote_down_off" title="Vote Down"></span> <span class="image vote vote_up vote_up_off" title="Vote Up"></span> </div> </div> </div><a name="a42710_12"></a><div class="message" id="message_42710_12"> <div class="message_header"> <div class="message_from"> From: CHYRON (DSMITHHFX)<span class="message_time"> 4 Dec 2020 20:15</span> <div class="clearer"></div> </div><div class="message_to">To: Matt <span><span class="image post_read" title="Read: 6 Dec 2020 19:54"></span></span> <span class="message_count">12 of 19</span><div class="clearer"></div> </div> </div> <div class="message_links"> <a href="lmessages.php?webtag=DEFAULT&msg=42710.12">42710.12</a> In reply to <a href="lmessages.php?webtag=DEFAULT&msg=42710.8#a42710_10" target="_self">42710.10</a></div> <div class="message_body"> The NAS doesn't talk to the UPS, it's the other way around.
