RE: Changing Console -- MIDRANGE-L

The system has a twinax card; it has a twinax controller; there were (in a
previous life) twinax devices attached to it.

It would be pretty much impossible to put a twinax cable if there is no
twinax card.
The original post did not exactly make that clear (or I am a bit slow this
morning - quite possible) so I was trying to determine if there was actually
a card in there.

It's really not that hard to put a twinax cable in that machine and
hook up a terminal to test it "before" changing the console type.
And then do a DSPDEVD on it to ensure that it's at the right port and
address to be your console.

Hi Jerry

when you say you have a twinax controller - are you saying that you
have a twinax card in that 520 - what kind of card is it ?
Hopefully this document works for you if you are going to use twinax:

Evan,

Thanks. I do have a twinax controller (plus Steely Dan's greatest

hits),

and I do (S/34 programmer that I am) have twinax cables (I store
them in

my

attic).

I sis forget to mention (senility is setting in) that once upon a
time

in

the west (re: Sergio Leone) that when this system was first
delivered it was configured for an HMC, even though ordered as
twinax (we converted

later).

The IBM tech (level one) had the steps (I think) memorized. I.e., I
had

to

go through steps on the control panel to switch it to twinax.

So, I'll accept an alternative. What are those mysterious steps (he

would

not slow down so that I could write them down)?

Hi Jerry

let's say you go ahead and change that second option to "1" (Twinax)
-

are

there any twinax cables connected to the system ?
Do you even have a twinax controller in the 520 ? (I am betting the

answer

to this is "No") I don't think the twinax bit of this plan is ever
going

to

work...

I think you will be forced to reconfigure the LAN Console to work at
the new site, but I would need more information to make any
suggestions on that score.

I have a system, which is currently using a LAN console, to a
twinax console. I know, I prefer a LAN console, too. In short,
this is for a company that is no longer in operation, but they
have to have access to the data for another year. I have to move
the System i (a 520 at
V5R4) from its current "home" to another location. Once I get it
moved, I may re-configured the LAN console (or I may just rest on
my laurels).

Anyway, I think I know how to do this, but I need confirmation
that my thought is correct and complete. I think the only thing I
need to do is run STRSST and change the second option on this
panel to '1'. It will probably
ask me (or force me) to re-IPL. Anyway, is this the extent of what I

have

to do?

Select Console

System:

Allow console recovery and console can be taken

over by another console . . . . . . . . . 1 1=Yes, 2=No

Select one of the following:

Console type . . . . . . . . . . . . . . . . 3

1. Twinaxial

2. Operations console(Direct)

3. Operations console(LAN)

4. Hardware management console(HMC)

Current state of console tag . . . . . . . . 0

Allow supported internal LAN adapter to

be the console . . . . . . . . . . . . . . . 1 1=Yes, 2=No

Allow supported Gigabit LAN adapter to

be the console . . . . . . . . . . . . . . . 1 1=Yes, 2=No
