OW AUTO-SHUTDOWN WORKS:
In the event of an ac power mains failure, the Power+ sends a notification to the IP addresses defined in the
PC notification and shutdown screen. This generates a pop-up message on the computer screen advising
of the ac fail condition, and starts a countdown. The countdown for each computer lasts for the number of
minutes specified in the “Ac fail delay” field. If this countdown is exhausted before ac power returns, the
Shutdown Agent saves and closes any open datasets on the computer and then shuts the computer down.
If during the countdown, the Power+ battery falls below a preset voltage (the low-battery voltage threshold,
defined via the Power+ controller), the Power+ notifies the defined computers of the low-battery condition.
This starts another countdown, that lasts for the number of seconds defined in the “Low battery delay” field
and also cancels any other active shutdown countdown. When this latest countdown is exhausted, the
Shutdown Agent saves and closes any open datasets on the computer and then shuts the computer down.
This takes place even if the “Ac fail delay” countdown was not yet finished.
