Can you send the variable list of upsrw and the command list of upsc for reference? I don't have any information on the 5E.

It's probably the latter, but if you don't hear the relay in the first case, that's a problem. > When the UPS reboots it beeps and I can hear a relay click so it must do > something when it reboots with power on. > > How can I add a delay between UPS power off, and power on? The output of upsrw will confirm this, but many HID UPSes have separate timers for delay before shutdown, and delay before turn-on (ups.delay.start). -- 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
