Yes. If the power has returned at this time (or never went away), it will send a 'reboot' command to the UPS, so that the PC will restart again. > - the UPS kills the power to the PC; > > - line power returns; > - the UPS see line power restored and restores power to the PC; > - the PC reboots (because it is set to boot after power failure). That is the idea. > If this is correct, why would we think that "upsmon -c fsd" would > cause the UPS to kill the power to the PC (without the changes to > /etc/init.d/halt)? It won't. I assumed you already did that. Sorry for that.
