> The console is a twinax terminal hanging off of port 0 on a twinax
>  breakout box attached to the only twinax controller.

If your other devices have sign on screens then your IPL ran fine & the 
problem is with the console connection, not with the IPL.

Your twinax controller may come with a "box" with 2 rows of places that you 
can connect & they are not super well marked ... you need to use a magnifying 
glass to figure out which one is port 0 & attach your twinax terminal to that 
one.

There is some place on the twinax terminal (like a SETUP key perchance, or 
power it off & holding any key (like the space bar) down, turn the power on) 
to tell it that it is address 0 on its port.  It may support multiple 
addresses.  One of them has to be address 0 & that is the session side you 
IPL from.

AS/400 twinax is a bit sensitive to the type of connection.
I have never seen console work with anything between the twinax controller & 
the twinax connection on the twinax terminal.
When we string twinax terminals together the cable needs to go from the 400 
to the 0 side of the first terminal, then next cable from the 1 side of first 
terminal to 0 side of second terminal, and you have to know how to terminate 
the tthing.
When it is a PC the connection is often a pigtain "T" in whcih the lack of 
something connected on one side makes it know that is end of line & the "T" 
direction is interchangeable, but some PC connections need some switch on the 
PC to say that it is the end of the line.

Now if you have cable through & it is hooked up wrong, like you using the 1 
side connected to the 400, some things sometimes work, but other things do 
not, so the first game is to make sure twinax hooked up right.

In addition to cable thru to various other twinax terminals in daisy chain 
format, you can have splices, in which there is a twinax connector that is 
same sex on both sides, but there is a limit to how many of these can be on a 
port, and a limit to how long from 400 through all chains to last guy on the 
end & God forbid that the end is not properly terminated or we have a 
phenomena known as antenna inteerference.

There are some other possibilities.
I assume you have the right password for the DST.
I assume the 400ds do in fact have OS/400 loaded.
I assume they do not have M36.

With M36 there is a little game in which the port 0 gets reassigned ... port 
0 is REALLY the 400 & port 1 is REALLY the 36 but M36 thinks its port 1 is 
port 0.

Do you know that for power off, push the white button & you get the IBM 
version of a question mark, meaning "Are you sure you want to do that?" Then 
you press again for it to take, but the panel might have some rules setting 
to allow this action.  Then wait until the 400 quits making noises, that you 
can hear, and give it a few more minutes before power on again try.
