What is the input voltage to the switch, 7.5V? I need to order some switching regulators, can get an extra one that meets power needs of switch if we want to run from lead acid battery. Alternately could boost from a regular USB battery bank that stays plugged into a wall wart to top off.<br />

as to the power, wouldn't a ups be nice for between the wall outlet & door system?</div>

Before I did that, the ethernet port was not getting a link at all, even when connected to a known good cable.<br /><br /> After the power cycle, its ethernet worked, but since I had not power cycled the USB hub and magstripe reader, it was giving errors until i rebooted it, and then it worked properly.<br /><br /> well i spoke too soon, it just came back online by itself.<br /><br /> The front door computer has a battery backup so that it can keep working even if the rest of the world disappears. But we won't find out about it losing power unless it has a connection to the internet.<br /><br /> presently it goes through at least one hub on the way back to the server area, and that hub does not have a battery backup, and apparently gets unplugged regularly.<br /><br /> I still think we should have a dedicated CAT5 ethernet run from the front door to the server rack, since this is such important infrastructure.<br /><br /> thank you<span class="HOEnZb"><span style="color: #888888;"><br /> -jake</span></span>

Let's not run that again if we can help it. I'll go check on it<br /> in a bit. We could do a new run up to the public terminals and just join it<br /> to the existing wire from the doorputer to get a dedicated run.<br /><br /> -- <br /> marc/juul<br /><br /> On Mon, Sep 19, 2016 at 8:02 PM, Jake <<a href="mailto:jake@spaz.org">jake@spaz.org</a>> wrote:<br /><br />
