RE: IXA installation - cannot see the adapter

Pete,

It's been awhile since I did an IxA, I don't recall the jumper info you
described.

But IIRC, the HSL loops are directional, both the cables and the ports
themselves have to be connected in the right direction.  The cables have
tags with arrows on them.  The port directionality can be found in the
manual.

Also, the SPCN cabling is a little strange, I remember spending a lot of
time looking at the diagrams till I figured out how it was supposed to
be.

If all else fails, call IBM.

Good luck,

Charles Wilt

Subject: IXA installation - cannot see the adapter

This is my first IXA installation and I am a little uncertain 
whether I 
have done things correctly.  I have a x366 xServer that I rack 
installed.  It had two cards installed in the xServer: an RSA II card 
and the 1519 IXA card (in slot 2, covering also slot 3).

At this point in the process I had a question that I couldn't get 
answered by the manual or other on-line resources.  The installation 
instructions (page 45 of the Integrated xSeries Adapter 
manual) refers 
to a step 6.  To wit:

"6. Provide 3.3v standby power for the card position by doing the 
following:

a. Locate J35 and install a jumper to connect the pins by 
doing one of 
the following.  For a 2-pin configuration, install a jumper 
to connect 
the two pins.  For a 3-pin configuration, move the jumper from the 
default position to the enabled position by moving the jumper to the 
uppermost 2 pins as viewed from the front of the server.

b. Locate J40 and install a jumper to connect the two pins.  
For a 2-pin 
configuration, install a jumper to connect the two pins. For a 3-pin 
configuration, move the jumper from the default position to 
the enabled 
position by moving the jumper to the rightmost 2 pins as 
viewed from the 
front of the server."

The thought that occurred to me was "I need to jumper 
something in order 
to get power to the cards?" So I didn't complete that step.  These 
failing bi-focaled eyes couldn't see those jumpers anyway.  
Perhaps that 
was my big mistake.

Next step - Cabling. Man!  These guys are expensive because of the 
cables needed to connect the xServer and System i together!  This is 
where my newness in installing one of these things left me 
uneasy.  The 
cable between the RSA card and the 1519  was well labeled and easy to 
install.  The SPCN cable went from the "little brick" SPCN adapter to 
the UPS (via a "Y" Cable).  However, I got uneasy with the 
HSL cables.  
Having never dealt with HSL cabling, I was uncertain how to establish 
the "loop". I connected one cable from the IXA to the System 
i, and then 
connected the other cable from the IXA to the System i.  
There seemed to 
be only one way to install these and the only thing I could have done 
wrong was establish the "loop" incorrectly.  Would that be 
important?  I 
ran the first cable from the left-most connector on the IXA to the 
topmost connector on the System i.  I ran the second cable using the 
remaining connectors.  Seemed *fairly* straight forward.

The problem is that I don't see the adapter when I use the WRKHDWRSC 
*CMN command.  I see a 268C resource type but the manual says that it 
should be a 2689 resource type.  I think the 268C is the 
Linux partition 
using virtual hardware.  But there is no 2689 resource listed.

Where should I start checking?  The xServer DOES boot when I manually 
turn it on.  I changed some BIOS settings as per the manual. 
So I think 
the issue is the System i "seeing" the IXA.

Any suggestions would be appreciated.

Thanks

Pete Helgren
