APC UPS BackUPS Pro (BX1500M)

I’m using apcupsd (installed via pkg) and have it set to gracefully shutdown my machines when the battery is nearly drained.  A couple of weekends ago, we had the power go out at night and my machines shut themselves off gracefully as expected.  Of course, I had to bring them back up manually when I got up, but I would prefer this than having them go down hard on a power outage.

Your situation may vary as to what you consider the appropriate response and recovery process for your machines, but I’ve had apcupsd do what I told it and automate the low battery shutdown.

The APC will supply power with its battery no matter what the device or OS, however, the sum of "drive"-current determines the rate of battery dissipation. I chose the 1500-watt model, APC Pro-1550-S.

I plugged in my main WAN computer, my ham radio, my Dell server, and a few USB hubs used for distributing disk-space specific-topic hard-drives and their BU hard-drives.
