<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=342523806-28092006>Thanks
jimmy for the hints, but I'm afraid the description of the problem I have was
not clear.</SPAN></FONT></DIV>

<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=342523806-28092006>The
problem I have is NOT a software configuration issue of NUT.</SPAN></FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=342523806-28092006>The
problem I have is that the UPS, when reaching battey.charge.low SHUTS DOWN
ITSELF IMMEDIATELY, without sending anything to NUT over the serial port.
Whatever would be my NUT configuration, it has no time to run, since the
computer is shut down immediately.</SPAN></FONT></DIV>

<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=342523806-28092006>The
UPS behaves exactely AS IF IT WAS NOT SUPPERVISED.</SPAN></FONT></DIV>

<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=342523806-28092006>My
guess is that there is some logic within the USBS 750 that makes him decide,
upon reaching the low battery state, to negociate with a software that
suppervises him (over the USB or serial port) OR, if not suppervised by
software, to shut down itself immediately to protect its
battery.</SPAN></FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2><SPAN

<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=342523806-28092006>My
guess is that this behavior is not properly working, and they may be two
reasons</SPAN></FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2><SPAN
class=342523806-28092006> * OR the Ellipse has a firmware
issue that makes him believe it is not suppervised when suppervised through the
SERIAL port (and not the USB)</SPAN></FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2><SPAN
class=342523806-28092006> * OR NUT is not properly sending
some commands to set some parameters to the UPS to make it enter the proper
mode.</SPAN></FONT></DIV>

Ellipse 750 USBS auto shutdown and NUT.<BR><BR></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

<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><FONT face=Arial

<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>
