on the same page, i've found that most UPS come with a cable that's the
same of the one avaiable on the end of the 1827 adapter i dont remember
right now but if the adapter ends in a male connector the cable also has a
male connector. Is it me or that is wrong? i'm about to MAKE the cable
since i just cant use the standard parts...

YES you need both. Also you will need to power cycle the server once the
cable are connected for it to recognize the UPS is there.

Ah, well, I was hoping the RJ45-DB9 female had the pins mapped, because
none of the docs mention a DB9 female.

I located an RJ45-DB9 male; should I use that and make up a DB9 f-f (and
map the pins)? Or should I leave the RJ45-DB9 f on the server and make
up a DB9 f-m (and map the pins)?

i believe you need both adapters, the rj45 to db9 and the db9 to db9. At
least thats what APC user manual claims.

The UPS has a communications cable coming out of it which terminates in
a DB9 male. Pins 5-9 are populated.

The server has an adapter cable IBM p/n 46K5108. One end is an RJ45
and
that end is plugged into port S2. The other end is a DB9 female.

It would seem like a no-brainer to plug the DB9 male from the UPS into
the DB9 female coming from the Power 7, but I'm wary of that because
the
Power 7 Systems Hardware information guide


http://pic.dhe.ibm.com/infocenter/powersys/v3r1m5/index.jsp?topic=/p7had/p7hadups.htm

doesn't mention an RJ45 cable with a DB9 female.

It DOES mention a f/c 3930 adapter from RJ45 to DB9 male and it also
mentions a f/c 1827 adapter cable which is a DB9 female to DB9 female.
It seems to me that the f/c 1827 is necessary to tell the service
processor a UPS is attached because it ties pins 2 and 7 together on
the
server side.

My system order shows that I ordered an 1827 but of course I can't
locate it from 9 months ago. I can make one up easily enough, so
that's
not a show stopper.

Do I trust the manual or is there a newer reference I should be looking
at? I'm not plugging anything into the back of the server until I am
convinced that it's OK to do so.
