You can monitor the ups.timer.* variables after sending the shutdown command; they should count down. There are some more details in the “Shutdown scripts” section of docs/config-notes.txt, or at http://www.networkupstools.org/docs/user-manual.chunked/ar01s06.html#_shutdown_scripts It also looks like your UPS has a watchdog. I haven’t tried this on the newer usbhid-ups models, but once you set the watchdog timer, the UPS will power-cycle the outlets if the driver does not communicate with the UPS in that timeout period. I am not sure if the watchdog is enabled after the reboot - this is definitely one of those cases where you will want to experiment with a dummy load on the UPS (and with the PC powered from another outlet). Does anyone else have any specific experience with these timers on a Tripp Lite UPS with usbhid-ups? -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
