This test was once again somewhat unsuccessful. The UPS seems to have shut off at 20%, unsafely killing power to all connected devices (oort, router and ONT). The UPS should have entered a "Low Battery" mode at 30%, which should have commanded oort to shutdown.

Due to some configuration errors, the last UPS test was not successful. The UPS performed as it should but oort did not shutdown upon reaching low battery. After fixing the configuration issue, I am now running the test again.
