It means no shutdown delay value has been configured. I already wrote that we'll need the NUT version and OS to determine what *exactly* is going on. > I Googled, but couldn't find anything > relevant. Am I correct in assuming it is this setting that caused the > immediate shutdown? No, the decision to shut the system down is unrelated to the ups.delay.shutdown value. Most likely (but see the note above), the UPS firmware is broken and it signals low battery right after the power is lost. NUT has no other option than to initiate system shutdown in that case. Note that the Back-UPS 350 is a *very* small entry level UPS that really shouldn't be used for anything other than small desktop systems. > Today, the UPS shows a load of 35, via the upsc > command, so it doesn't appear it was overloaded. Maybe, maybe not. The only way to conclusively tell why NUT decided to shutdown the system is to run the driver in debug mode. It will probably confirm the above.
