I'd like to share some of my experience with this UPS. I've compiled nut from the Debian sid sources. Version is 2.2.1. I'm using the powerpanel driver. It seems shutdown.return does in fact what shutdown.return should do. I'll just copy&paste some of my notes made yesterday: Commands were issued as follows: "upscmd -u admin -p admin bbox at localhost shutdown.reboot". Shutdown tests: shutdown.reboot (tested with S01R0001) OB: - poweroff after 1min - does not restart load - restarts load immediately on OL OL: - poweroff after 1min - restarts load immediately (if OL) shutdown.return OB: - no effect OL: - no effect shutdown.stayoff OB: - poweroff after 1min - stays off even if power returns (OL) - have to cycle from button to restart load OL: - poweroff after 1min - stays off, but powers on immediately if power is cut & returned S01 - 1 minute S02 - 2 minutes R0001 - restart immediately R0002 - restart immediately?! R0003 - restart after 1min R0005 - restart after 3min R0007 - restart after 6min R0010 - restart after 9min R0015 - restart after 14min I also tested with R0015 and without plugging it in. After some 14minutes the UPS beeps (timeout expires) but nothing happens. On returning power, it starts the load immediately. I tested again with R0005. After the load was cut off, I pulled the plug. After 3min 30secs (it restarts after 3min sharp if OL) I plugged it back in, nothing happened. After some 25 secs, the load was started. -- Valkai Elod Network Administrator RC TEAM SA, Timisoara, Romania
