After the first test and the NAS is restarted I had to change the setting
battery.charge.low again to 80

The APC produced an audible clunk. So the UPS was shutdown. I am not sure it
was after 20 seconds. I have to clock that.

Result test 1
1. Pull power cord from wall. — OK
2. UPS beeps, NAS and Mac continue operation
3. Users from the NAS are warned, not yet the Mac user. Only when executing
automatic power-fail shutdown.
4. Yes, Both the Mac and NAS shutdown. Only the Mac shutdown so fast that it
looks like pressing the off button. The NAS I have to check if it was in
safe-mode some how.
5. The UPS shuts down. I heard an audible clunk.
6. Reconnect the wall power — OK
7. No they didn’t restart. I know there is a setting on the NAS to activate
this. I will check and try again.
This is what is reported from the terminal on the Mac:
