2843, 27844 and 2838

[Joe Pluta <joepluta@xxxxxxxxxxxxxxxxx>]

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.
