CPF181A Message

Over the weekend, we experienced multiple brown-outs/black-outs to our data
center.  Our server farm (including 2-AS/400s) are fed by two APC Matrix
5000 UPS units.  There is a communications cable between one UPS and our
mail server, and this unit sends out the pages for "on battery" and "utility
power restored".  There is no communications cable to either AS/400.

On our model 720 (V4R3), I show messages logged stating:
CPF181A - Message . . . . :   System power failed at 000805154915.

Cause . . . . . :   The system's power failed and power was switched to
internal batteries.

CPI097A -       Message . . . . :   System power restored at 000805154926.

Cause . . . . . :   The system's power source failed and was switched to run
on internal batteries for 11 seconds.  The system remained powered during
this time, and no recovery is necessary.

A couple of questions came to mind:
1)      Since there was no cable between AS/400 and the UPS, power should
not have been interrupted.
2)      The other AS/400 (a model 300) was on the same UPS, but showed no
power messages logged.

What is the difference between CPF1816 (System Utility Power Failed) and
CPF181A (System Power Failed)?  If a RTFM is a valid response, please give
me a clue as to which one!  I've looked on the Web and the CD to no avail on
this message.

I'm hoping that since the UPSs were cycling on and off (5 times within a
half hour) had something to do with that.  The 720 is the only 208 volt
machine on that UPS, so maybe the power wasn't "clean" enough?  Or worse,
might I have a problem with the 720's power supply that just happened to
show up during a power failure???

Any ideas???
