Re: IXA resource failures

Pete,

You should have received a SPCN mini-brick with the IXA adapter. On it you
will find two ports J15, the input side, and J16 the output side. You should
have two SPCN cables one from SPCN 0 on the System i to J15 and one from J16
back to the SCPN 1 on the System i.

Kind regards,

BJ

Tom,

That was my suspicion as well, that the HSL/SPCN cabling was amiss.

So, based on my prior post:

First, the HSL cabling:  Fortunately I
can't connect them in the wrong "direction" since each end has a unique
connector that only plugs in one way.  However, I could have them in the
wrong *order* (I am guessing).  I have them as follows: Cable 1 goes
from the xSeries Port 0 to the HSL port on the System i called "T1".
Cable 2 from the xSeries Port 1 to the HSL port on the System i called
"T2". Is that correct?

Second, the SPCN cabling.  There is a J15 port on the xSeries.  I cabled
this to the SPCN 0 port on the System i.  Is this correct?


What would be the answer to #1.  It that correct?  And, if #2 is NOT
correct, how do I cable the SPCN when there isn't a J16 ?  The manual
says that we should use a "Y" connector for the SPCN cable but where
would the other leg of the "Y" go?

Service tools shows this:


                                             Serial
Opt     Frame     Unit     Type     Model     Number         Fault
       03C00      00      787F      001      DP-M09V2       No
       03C00      01      787F      001      DP-M09V2       No
       00002      00      TMP0      002      01-EF97B       No
       00002      01      TMP0      002      01-EF97B       No

What should I be seeing ?

Thanks,

Pete
