I like to test my ups' to see what the message is.  If you're too nervous
to pull the plug to your ups it is time to dump your ups and get a
different one.  I've thrown the master breaker to the computer room a few
times to test the ups.  I like doing this with the new guys right after
we've entered the computer room using their pass key.  It controls
multiple iSeries and W2K servers.  I get a big kick out of watching the
newbies wet themselves.

CPF1816-System utility power failed at 020412144014.
CPF1817-System utility power restored at 020412144022.

Doing a DSPMSGD CPF1800 you'll find a plethora of power messages mixed in
with other messages

Then there is the SCNMSGF utility available at

Scanning for UPS I see:
Message    Sev Text
CPI0961     80 Uninterruptible power supply (UPS) no longer attached.
CPI0962     80 Uninterruptible power supply (UPS) now attached.

CPI0975     80 UPS no longer bypassed.

CPP3504      0 UPS battery low condition turned off
CPP3505      0 UPS reported bypass no longer active

Scanning for power I see:
...
CPF1821     90 Power failure. System ending. Restart IPL will be ignored.
CPF3421     30 Attempting recovery from possible power loss on device &9.
CPF6A04     30 Device was powered off so open was not attempted.
CPG0545     20 Power of 10 for tick definition not correct.
CPIA959      0 Printing power on/off schedule.
CPI0961     80 Uninterruptible power supply (UPS) no longer attached.
CPI0962     80 Uninterruptible power supply (UPS) now attached.
...

Which brings up another good test.  Leave the power plug from your 400
into your UPS but remove the power warning interface cable from the UPS,
wait 20 seconds and plug it back in.  You should get CPI0961 and CPI0962

Rick,

Your system should have powered down 200 seconds following the loss of
power.  However, you should also have received messages in your
designated queue (and QSYSOPR I believe) related to loss of utility
power at the moment power was lost.  If you received no messages, it
sounds as though your UPS and the hardware cable are not configured
correctly.  This is purely related to the UPS and the cable, there is no
configuration required on the OS/400 side.

Andy Nolen-Parkhouse
