Apcupsd is short for APC UPS daemon and is used to interact with and monitor APC UPSes. While initially designed for the APC, it can also talk with some other brands of UPS, including some by Cyberpower.

The following DIY manual describes an easy-to-implement battery backup module for the BeagleBone Black. This can be useful in certain applications, such as out-door usage where constant power is not present and it is not desirable to just drop power on the BBB board. It was built for a RasPBX setup with the motivation to have a safely powered BBB in all situations. The BBB is unfortunately suceptible to slowly rising supply voltage when powered on. It sometimes does not boot at all, which can be a serious problem after a power glitch. On top, voltage irregularities can cause the device to crash as well.
The battery backup can be applied to any BBB installation, running RasPBX, the original Anstrom Linux or any other distribution. However, USB devices cannot be used while running on battery, as the UPS does not power the USB host port.

The APC PowerChute utility will only run in Windows, but if you are running Ubuntu Linux (or some variation thereof) you can have pretty much the same thing by following the instructions in this article:
Configuration of APC UPS in Ubuntu (Tech-Niche)
The article suggests you install gapcmon but you probably don’t need to do that, because Ubuntu already includes a Power Statistics utility that works well enough for most users.
If you have problems getting it to work, make sure the USB cable is plugged into the correct jack on the UPS (with some models it’s easy to plug it into a network cable jack by mistake). From the command prompt issue the command lsusb and it will tell you what is connected to your USB ports — you should see an entry for “American Power Conversion Uninterruptible Power Supply” if the cable is correctly connected.
