I have observed the 0B status.
Concerning the LB, I have not yet really test it (see below).

I have not yet made such a test.
I have one new cluster, one old cluster, and a new workstation.
So far, I have played with the upssched features on the new computers.
Now I must play with the old computer: this may take some time.
Once the all computers are ready, I will make such a test.

What I can say right now is that when I do

/sbin/upsmon -c fsd

everything shutdown as expect, except the UPS box.
Right now, my guess is that

/sbin/upsmon -K

does not work as expected.

I have not yet modified the /etc/init.d/nut script provided by the Debian (Lenny) package:
at the very end, I get the message:

"Power down flag is not set (UPS shutdown not needed)"

which is due to a FALSE response (IfThenElseFi) of

/sbin/upsmon -K

To be frank I do not get the message:
I ask to shutdown the UPS box,
so I do not understand why the machinery do not do so.
In short, "I do not care that ``UPS shutdown (is) not needed''" !

In the manual page of upsmon, we read:

       -K     Test for the shutdown flag.  If it exists and contains the magic string from upsmon, then upsmon  will
              exit with EXIT_SUCCESS.  Any other condition will make upsmon exit with EXIT_FAILURE.

What is the expected magic string ? is this string come somehow from the UPS box ? 

Does I miss something here ?

Meanwhile I got a feed from a Delta user:
he suggest to use belkinunv. I let it a try,
but it did not work.

Thanks in advance,
