UPS Attachment to an i5 520

Folks:

A few months back I posted about UPS attachment to a 520.  There have been
discussions on it various times.  Here I go again because something just
seems rotten in Denmark.

I have a UPS monitoring program since wwwaaayyy back when.  Have used it on
at least 4 incarnations (an F45, 300, 270, and now 520).  It dawned on me a
couple of months back that UPS program no longer issues the "UPS is
attached" and "UPS is no longer attached" messages which are the result of
receiving CPI0961 and CPI0962 messages, respectively, on the UPS message
queue.  But my program has not changed.  What has changed is the 520/550/570
models are different.

There is no longer a J14 UPS sense port on a 520/550/570.  Instead these
models use a serial port.  But it's not the same as a J14.  

After going round and round with my CE (and he with IBM support) over a
couple of months, I got a document from my CE which states (among other
things): 

"Feature 1827 is designed to connect to the UPS via the UPS signal cable.
The Service Processor will detect the presence of the UPS at IPL time and
set the signal control for the UPS.  A reset of the FSP is required once
FC1827 is physically attached, this allows the port to be initialized as a
UPS sense port.  Message CPI0962 is logged in QSYSOPR when the i5 Operating
System partitions are IPL'ed ONLY (emphasis IBM's) if the UPS sense cable is
attached to FC1827.  IF THE CABLE IS REMOVED DURING RUN TIME, THE SYSTEM
WILL STILL THINK THE UPS IS ATTACHED." (emphasis mine)

Am I missing something here?  This is Not A Good Thing.  To top it off,
after IPLing, I do not see that CPI0961 in QSYSOPR.  As near as I can tell
(you'll have to see a thread from months ago about this) there is no way for
me as an end user to tell, once the system is powered up, whether the system
thinks a UPS is attached.  Is this not a step backwards from what we had for
years and years?  Maybe I'm just dense.

Thanks.

BTW, the 595 still has the J14.  Only multimillion dollar customers need
real protection, eh?
