Do you use the bcmxcp driver ?

Yes the bcmxcp driver is included in 2.0.2. But you should use the
Testing or Development branch of the cvs. The driver have been updated
to support different baud_rate and it also init the ups to run in
requested mode only.

If you use the bcmxcp driver, then the value for shutdown_delay is not 
the time after it goes to battery.

It works like this. The shutdown_delay is calculated to a maximum at 
the current load in the ups. If you set it to high in the config you
get a warning that the time is to long to run after low_battery.

So when it goes to battery it runs as long as the battery is not 
signaling low_batt. When it gives on_batt low_batt (OB LB) then
the upsmon is signaling the system to shutdown. Then you have the
time of shutdown_delay to take the system down.

This is the same for all (i think) drivers. The thing is that you 
want it to run as long as possible on battery. The line power may
But if the ups go to LB it need to shutdown.

So give us some more info and as Charles say, the config files
and we help you out.
