Nut upsdev - Jun 2014 - Question about recycle power of Tripp Lite UPS

Hello,

We are trying to develop a mechanism to power cycle Tripp Lite UPS. When we
checked the upscmd, looks like the only command we can use is
shutdown.reboot(sudo upscmd -u user -p password ups shutdown.reboot).
Because the PC is connected to UPS directly and we would prefer shutdown PC
before power cycle the UPS. But if we run shutdown PC first it won't run
the power cycle the UPS script any more. Wonder if there is a delaed power
cycle command for Tripp Lite to give PC some time to shutdown itself?
Attached the upscmd -l and upsc ups.

Thank you for your help

[moving this to nut-upsuser, since other users of Tripp Lite equipment may have
specific experience with this.]

You should be able to set ups.delay.shutdown to the amount of time it takes the
PC to shut down (plus a buffer), then send ?shutdown.reboot? from the PC.

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?

The upsmon.conf has the option of setting   RUN_AS_USER username 

Might it be possible to add a similar option to the upsd.conf file?

I see the -u command-line option for both upsmon and upsd, however,
upsd doesn't seem to carry that to the configuration file, as upsmon
does.

Thanks.

Hello Charles,

Thank you for your comment. Just tried to use ups.delay.shutdown to
postpone the UPS shutdown. The thing is that if the PC shutdown first, then
the UPS, it wasn't able to send "shutdown.reboot" any more because
everything is power off after the UPS shuts down.

Also play on the watchdog for Tripp Lite. Looks like it has the command of
reset.watchdog but not enable.watchdog. Do you guys know the command to
enable the watchdog for Tripp Lite UPS(TrippLite HID 0.8)?

Thank you so much for your help
