Nut upsuser - Sep 2016 - How to send shutdown signal to UPS hardware?

I learned earlier from Roger Price's excellent explanation that a proper
configuration includes sending a 'delayed shutdown' signal to the UPS
hardware prior to shutting down the server.

How is this accomplished? Does the USB driver handle this for us or must we do
something additional?

Thanks,

It depends on the driver. Look in the manual for your driver and check if it
have any extra arguments. 
For example the driver I was involved in "bcmxcp" has a shutdown_delay
that
set the time between receiving the command and actually shutting off.

USBHID-UPS have a offdelay.

"
offdelay=num
Set the timer before the UPS is turned off after the kill power command is 
sent (via the -k switch).

The default value is 20 (in seconds). Usually this must be lower than ondelay, 
but the driver will not warn you upon startup if it isn?t.
"
You set this in the "ups.conf" file.

Got it, thanks.

I realized shortly after I posted my question that this should involve some
rtfm, so I appreciate your patience.
