The only thing for this vote is in bold, below. It's just for the 2
UPSes already purchased. If HamWAN doesn't want to fund it, I'll
eat it out of pocket or sell the equipment.<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
During the recent wind storm event in January, HamWAN lost
utility power to some sites. This triggered network outages
that affected users and repeaters that relied on those sites.
It was far from our finest hour. "When all else fails",
HamWAN should not be the first in line. I'd like for 2021 to
be a year we focus on reliability. Having a reliable power
system at every site seems like a good place to start that
journey. In each of the power failures in January, a
generator system failed to activate. In these cases, we need
at least 24 hours to mount a response in fixing generators.
This means our battery backup systems should be sized for at
least 24 hours of runtime. I have acquired a couple UPSes
that can achieve this. They are composed of the main UPS:<br>
<br>
<a

<br>
And one external (and chainable!) battery expansion module:<br>
<br>
<a
href="https://www.apc.com/shop/us/en/products/APC-Smart-UPS-XL-Modular-48V-Extended-Run-Battery-Pack/P-SUM48RMXLBP2U"

<br>
They also feature an AP9631 network interface module in each
UPS, so we can monitor and control the power system. As you
can see, each UPS costs about $3600 new, so the two I acquired
would be $7,200 new. However, I managed to find used units
and purchased brand new batteries for them. <b>The total
cost for these two systems is $963.71.</b> One of them is
deployed at Rattlesnake ("Snoqualmie shack") already:<br>

<br>
If we ever want to expand the battery capacity of these, we
can simply plug in more battery modules.<br>
<br>
I'm hoping to deploy the 2nd system in the other building on
Rattlesnake ("DNR shack"), but that hasn't happened yet.<br>
