<br>
of course your ups doesn't behave normally :). <br>
I simply tried to find some workarounds in case your Ellipse ups shuts
down again without warning and upssched could certainly help you in
that way. <br>
<br>
Anyway, since Arnaud answered your mail, your Ellipse will soon be on
the safe side ;)<br>

immediately to protect its battery.</span></font></div>

<div><span class="493401906-27092006"><font face="Arial" size="2">I've
installed & configured NUT 2.0.4 connected over a serial port to an
MGE USBS 750.</font></span></div>

<div><span class="493401906-27092006"><font face="Arial" size="2">When
the UPS enters the 'critical' state (ie, battery load below the defined
battery.charge.low AND power input off), the UPS just shutdown itself
instead of notifying NUT. </font></span></div>
<div><span class="493401906-27092006"><font face="Arial" size="2">When
I say the UPS just shutdown, I mean it autonomously shut down itself
within one second after reaching the low battery state (which is
defaulted to 30%). When the power is restored, the UPS restarts
properly.</font></span></div>

<div><span class="493401906-27092006"><font face="Arial" size="2">I
was not able to find internal parameters within the UPS that would
allow me to cancel this behavior (and have the usual behavior of the
UPS sending an alarm to NUT and waiting to be shutdown by the "halt"
script upsdrvctl shutdown command).</font></span></div>
<div><span class="493401906-27092006"></span> </div>
<div><span class="493401906-27092006"><font face="Arial" size="2">My
guess is that the UPS "knows" if it is connected to an host or not.
Maybee in case of using the serial port this does not work ? (and the
UPS thinks it is not suppervised ?) Maybee shall NUT send it some
command at some point to notify this ?</font></span></div>
