Re: [Nut-upsuser] Power Walker VI 2000 LCD
2010/12/20 Alexander Todorov atodo...@otb.bg Hello, there's a recent thread about this or very similar model but without much info: http://lists.alioth.debian.org/pipermail/nut-upsdev/2010-October/004968.html I have this UPS and I'm trying to use it with nut-2.4.3 and megatec_usb driver: The ups id iin ups.conf is powewalker. /var/log/messages says: Dec 20 22:22:16 kvm-dom0 upsd[1666]: listening on 127.0.0.1 port 3493 Dec 20 22:22:16 kvm-dom0 upsd[1666]: listening on ::1 port 3493 Dec 20 22:22:16 kvm-dom0 upsd[1666]: Can't connect to UPS [powerwalker] (megatec_usb-powerwalker): No such file or directory Dec 20 22:22:16 kvm-dom0 upsd[1667]: Startup successful Dec 20 22:22:16 kvm-dom0 upsmon[1670]: Startup successful Dec 20 22:22:17 kvm-dom0 upsmon[1671]: Login on UPS [powerwal...@localhost] failed - got [ERR ACCESS-DENIED] Dec 20 22:22:22 kvm-dom0 upsmon[1671]: Poll UPS [powerwal...@localhost] failed - Driver not connected Dec 20 22:22:22 kvm-dom0 upsmon[1671]: Communications with UPS powerwal...@localhost lost What does (megatec_usb-powerwalker): No such file or directory mean? Which directory is this? this is the communication socket between the driver and upsd (the server). first, can you try with blazer_usb, since it's set to replace megatec. Next, after having stopped NUT, launch the following (as root): $ /path/to/blazer_usb -DDD -a powerwalker let it run for ~30 seconds, and send us back the output. also send us your ups.conf, along with the output of lsusb cheers, Arnaud -- Linux / Unix Expert RD - Eaton - http://powerquality.eaton.com Network UPS Tools (NUT) Project Leader - http://www.networkupstools.org/ Debian Developer - http://www.debian.org Free Software Developer - http://arnaud.quette.free.fr/ ___ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser

Which directory is this? this is the communication socket between the driver and upsd (the server). Hi Arnaud, thanks for the explanation. Is the missing directory a bug or this is indication that the incorrect driver was used? first, can you try with blazer_usb, since it's set to replace megatec. Next, after having stopped NUT, launch the following (as root): $ /path/to/blazer_usb -DDD -a powerwalker I tried blazer_usb instead of megatec_usb and things now seem to work. I get messages on the console when the UPS goes on battery or when on AC power. FYI (now on battery): # upsc powerwalker battery.voltage: 24.60 battery.voltage.nominal: 24.0 beeper.status: enabled device.type: ups driver.name: blazer_usb driver.parameter.pollinterval: 2 driver.parameter.port: auto driver.parameter.vendorid: 0665 driver.version: 2.4.3 driver.version.internal: 0.03 input.current.nominal: 9.0 input.frequency: 50.1 input.frequency.nominal: 50 input.voltage: 3.4 input.voltage.fault: 3.9 input.voltage.nominal: 220 output.voltage: 221.0 ups.delay.shutdown: 30 ups.delay.start: 180 ups.load: 0 ups.productid: 5161 ups.status: OB ups.type: offline / line interactive ups.vendorid: 0665 I have an additional question though. According to the docs NUT will execute the SHUTDOWNCMD when the battery level becomes low/critical. Is there a way to configure when the battery level is considered low? For example - shut down when battery reaches 50% of its charge.

For example - shut down when battery reaches 50% of its charge. You'll see in the above output that your UPS doesn't report battery charge. The blazer_usb driver can attempt to guestimate the charge remaining (see 'man 8 blazer'), but since the UPS doesn't report the load either, this will not be nearly good enough to base a decision to shutdown on. We really have no reliable means to determine charge remaining if the UPS is not providing us with the necessary measurement values. You'll have to rely on the UPS to warn about a low battery well before it is actually empty to shutdown. If this is not what you want, buy a different UPS that is smart enough to keep track of the charge remaining without the help of a NUT driver. It will invariably also support changing the value at which it decides when the battery is low.

I configured the guesstimate settings described in the man page. Does this mean that when the battery charge reaches the value of default.battery.voltage.low it will shut down? Sorry for asking but I'm using UPS on Linux for the first time.

I configured the guesstimate settings described in the man page. Does this mean that when the battery charge reaches the value of default.battery.voltage.low it will shut down? No, see above. This only works if a UPS reports the battery charge itself. The values drivers can calculate are not accurate enough to base a decision on. There is no way to keep track of the battery charge- and discharge current that would be needed to accurately calculate the charge remaining. We also have no idea what is happening to a battery when a driver is not running.
