Re: UPS signal status

[Pete Helgren <Pete@xxxxxxxxxx>]

I have a similar problem as Armand and I should probably submit a DCR to 
IBM because I really don't think it works in a way that is helpful.  I 
think that if a "weak battery" condition is detected during a "power 
failure" there should be a delay, set by a system value, that allows the 
i to wait a user defined # of  seconds before beginning the power down 
sequence.  An immediate shutdown when a millisecond drop in power is 
detected just seems silly.  Sure, a "weak battery" is unpredictable as a 
backup power source but when a transient power blip can bring down your 
system, *that* seems a little anal retentive to me.  Give me the option 
of determining how many seconds the power has to be off when there is a 
"weak battery" before shutting down.
