Re: 2843, 27844 and 2838

'Who owns what' is kinda the key question! There is one IOP (286d maybe) that doesn't exist as a separate physical entity in a 270 it's on the planar (a.k.a. mother board). That card in a 270 controls the very bottom slot (C01-RAID card) as well as the top two slots (C07 probably a comm card such as 2793 and C06 likely your Twinax card.) Then you probably have the 2842 in slot C05 or C06 with the 2838 Ethernet card below that.

As Kirk mentioned the simplest is to pull the 2746 (Twinax) card and put the 2nd 2838 in there and it can become your console. You must remove the Twinax card or you'll be hosed because you'll have three console capable cards in there and that's a no no.

As he mentioned you'll use SST to assign the IP address to the card. This will be an additional IP address assigned to your system and needs to be in the same network as your system console PC. Wen you configure the PC as the console it's going to want a Device ID and you will want to use QCONSOLE for that. Also be SURE to use V6R1 or newer for the System i Access on the PC as that is more reliable and eliminates one annoying password. Note that the console component isn't installed unless you select Custom and include Operations Console.

I've been living dangerously without a console, but I really have to
address this. Simple jiggling hasn't worked, but I really need to get
the box out of its little area and get some better access to the cables
and connections. Before I do that, though, I want to prepare for any
major surgery I might do.

One thing I may do is insert attach a second Ethernet card and go to the
LAN Console. Currently my configuration indicates as near as I can tell
that I have a 2842 adapter and a 2838 PCI IOP. This gives me a single
Ethernet line. I have in my posession an additional 2838 as well as a
2843 adapter. My quandary is that I have no idea what is compatible
with what. Can you have both a 2842 and a 2843? If so, how does each
2838 know who it belongs to?

I'm so confused.

And while I'm obviously leery of doing any messing about at all with the
Ethernet while the console is on the fritz, at the same time if I get
the console working I'd like to install the new Ethernet while I have
the machine up on blocks, so to speak.

So, is there a place that will tell a complete hardware idiot which
cards are compatible with one another, and with the box?

The box is a little bitty (2GB/80GB) 9406-270 without a lot of cards.
It's got a 284D and a 2842 and I don't use the 284D for much of
anything; QTILINE and QESLINE are always varied off. It's running V5R4
with cumes from February of 2008.
