The basic configuration is that upsmon will shut down the system (running SHUTDOWNCMD in /etc/nut/upsmon.conf) when the UPS signals that its battery is low. Your UPS probably indicates this currently: $ upsc tl ups.status 2>/dev/null OL The last line will change to "OB" when the power fails, and "OB LB" when the UPS has passed one of its low-power thresholds. It looks like this UPS supports both a battery level threshold, and a time-remaining threshold: http://networkupstools.org/ddl/Cyber_Power_Systems/CP1500PFCLCD.html * battery.charge.low * battery.runtime.low You can adjust these with the "upsrw" command, but I don't think we have verified whether the settings are stored in non-volatile memory on this particular UPS. > I had problem initially starting: > > mythuser@amethi:/etc/nut$ sudo upsdrvctl start > Network UPS Tools - UPS driver controller 2.7.2 > Network UPS Tools - Generic HID driver 0.38 (2.7.2) > USB communication driver 0.32 > Can't claim USB device [0764:0501]: could not detach kernel driver from > interface 0: Operation not permitted > Driver failed to start (exit status=1) > > But that appeared to be resolved by unplugging USB cable and replugging it. > This bug still applies: https://bugs.launchpad.net/ubuntu/+source/nut/+bug/1540008 I should add a fix for that to my PPA build. Speaking of which, there have been some long-term stability bugs related to the USB controllers on newer motherboards with the particular USB access method that NUT uses. Full history is here, but towards the end is a success story with a similar UPS (1000PFCLCD): https://github.com/networkupstools/nut/issues/300#issuecomment-263090233 The PPA switches NUT from libusb-0.1 to 1.0. https://launchpad.net/%7Eclepple/+archive/ubuntu/nut _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
