First disconnect the com cable from the iSeries to the UPS.
Second have the UPS service to make sure all is ok.
Third, make sure the message queue is allocated that the UPS system
values point to.
Fourth, reconnect the UPS com cable and test a power failure (off hours
after you have completed a full backup so you don't crash your iSeries
again. Perhaps only one partition up and running.) I know, that is
impossible. ;-)
If it is not the UPS then it is a missed wired com cable.

Subject: System i thinks POWERWARE 5125 batteries are weak
Our two LPARS did an abnormal shutdown at 8:05 this morning after a sub
second power failure because it detected weak batteries in the UPS. The
UPS is a POWERWARE 5125 that has performed flawlessly in the past and
has given no indications of weak batteries (it's not sounding an alarm
or flashing the low battery indicator).
Here are the messages from this morning:
Date sent . . . . . . : 07/11/07 Time sent . . . . . . :

Message . . . . : System utility power failed at 070711080331.

Message . . . . : Weak battery condition exists.
Cause . . . . . : The external uninterruptible power supply (UPS)
indicates
a weak battery condition. If utility power fails during this
condition, the
system may begin an immediate shutdown. See the Backup and Recovery
book,
Has anyone run into anything similar? Any advice on making sure this
doesn't happen again?
For what it's worth, this was the first abnormal shutdown we had on our
AS/400/System i units in the seven years I've been maintaining them.
