<tt>Hi,<br>
<br>
My colleague asked me to mail this info. <br>
It seems the problem only occures when using the usb interface.<br>
<br>

<pre wrap="">What makes you think these are false alarms?
</pre>
</blockquote>
<pre wrap="">I have 2 reasons for believing these are false alarms:
1) The UPS doesn't beep and none of the status leds change when this
occurs. I configured nut to page me for 'on battery' events, and while
working in the server room I witnessed how NUT complained but the UPS
didn't give a sign. In contrast, when it goes on battery because I
pull the plug, it beeps, leds flash, ...
</pre>
</blockquote>
<pre wrap=""><!---->
How long it takes before a UPS starts to beep and whether or not it will
beep at all for glitches, is something that is rarely specified. Don't
count on it.
</pre>
<blockquote type="cite">
<pre wrap="">2) Three other servers (not backed up by ups) who share the same power
distribution unit as the UPS are not affected. If these alarms are
real, it means voltage drops to 160V. I thought that would shut a
server down. Maybe you are right and a server can handle this for a
few seconds?
</pre>
</blockquote>
<pre wrap=""><!---->
Not necessarily. When a UPS detects a mains glitch, it will usually go
to battery for a couple of seconds and then return. So even if the power
fails for just a couple of milliseconds, it will be on battery for a few
seconds. Most (if not all) servers will tolerate a complete loss of
input power for at least a full cycle (20 ms) and even longer than that
for brown outs. So the fact that other systems don't notice this, is no
indication either.

<pre wrap="">I'm almost sure the mains are OK since the building is less than 2
years old.
</pre>
</blockquote>
<pre wrap=""><!---->
That by itself tells nothing. Remember the recent deaths of patients in
an italian hospital where the builder swapped nitrous oxide and oxygen
lines? That department was brand new too, but sadly eight people died
before they found out.
</pre>
<blockquote type="cite">
<pre wrap="">Also I connected the UPS to another socket across the room to no
avail. I agree there might be electrical glitches, but wouldn't the
UPS beep then?
</pre>
</blockquote>
<pre wrap=""><!---->
Not necessarily. Many will only start to beep when the mains is really
out, to prevent nagging people for each and every transient.
To rule out problems with the USB port, could you try connecting this
UPS via a serial port and the 'mge-shut' driver? You might also run it
in debug mode, but this will probably result in huge amounts of data
since the protocol this UPS uses is very verbose.
Best regards, Arjen
