Can you upgrade to 2.0.5, or any better if you can use the svn trunk. 
There is a bug in 2.0.4 in the shutdown, so the shutdown delay would not
work as expected.

And in 2.0.5 I use the topologi block that is not present in older
ups'es using the bcmxcp protocol. But this is fixed in the svn trunk.


But the error you get come from another thing. Some powerware
ups'es signaling the OB an LB via the alarm block. So the driver is
made to check if the alarm is present, then it use this to set the
LB status.

There may be a different alarm-map in your ups.

Start up the driver like this.

/pat/to/bcmxcp -DD -a blah

And sen me the output then i can see what alarms you have.
