[Nut-upsuser] upsmon/upssched shutdown problem

we're trying to do something that's perhaps unorthodox, but seemingly 
should work; but not for me.

We've got a Powerware 9315, that we are serially attaching one machine to. 
We have several classes of systems that we want to have shut down at 
different times.

I've been doing my config testing by attaching the master machine to a 
Powerware 9120, and yanking the power chord.

Master: I've successfully configured the one machine so that it detects 
power loss, starts a timer, and shuts itself down.

Slave: I've successfully configured one machine to monitor as a slave, it 
detects that master's gone on battery, but won't start a timer, nor will 
it shut itself down.  Although it will accept the signal from the master 
to shut down.  On the slave, I've got the configs and directories set up 
with same privs as on the master, but for whatever reason, it doesn't look 
like upsmon calls upssched or starts a timer.  Perhaps I'm mistaken in how 
I think the slave should act?

What I'd like to be able to do, is have a ranking of machines such that 
one class of machine shut themselves down after some very short amount of 
time (~30 seconds?) of on_battery; another class shuts themselves down at 
some low battery level, and the master shut itself and the UPS itself down 

Any pointers/help would be GREATLY appreciated.
