Re: 5494-002 from T/R to Ethernet -- MIDRANGE-L



Oliver,

Ok, let me think about this.  The SRC 540404 essentially means that the test
frame sent by the 5494 was never answered.  Which confirms that something is not
configured correctly at the address level.  It's been a while since I have had
to deal with this.  We used to do this but eventually put in a ETH card in the
AS/400 to communicate with the ETH attached 5494's.

You will have to invert addresses.  On the AS/400 side you will want to invert
the address of the 5494.  On the 5494 you will have to invert the address of the
AS/400.   I hope that makes sense.

Now, you can cheat and overide the adapter addresses to something that will
invert to themselves.  If you do not have a lot of devices to do this with this
may make life very easy.  If you have lot's of devices it may make address
management a bear.  There are certain numbers that invert to themselves.
Anyway, numbers like 42, 66, and 24 will invert to themselves.  For example you
can have the 5494 addressed as 420000002424 and use this address on the AS/400.
I would assume changing the TRN address isn't easy but something like
420000000024 or whatever will work.

If you don't want to address these cards manually then invert the target
address.  Leave your source address alone.  I used to actually have a program
help me do this. I think even CA/400 had a program to do this.

Hello,

we are currently migrating our network from tokenring to ethernet. We
already have an ethernet backbone and our 620 is
connected to both lans.

On a second site, we have a small t/r with a 5494 attached, going to the
main site by leased line and routers (CISCO 2500).
The 5494 connects to the t/r adapter of the AS/400, but I need it to go to
the ethernet card.

I tried to configure the 5494, but couldn't get it connecting. I've been
told by IBM  that I might have to translate the
adapter adress to ethernet format - but which one or both? I have two
adapter adr on the config screen ( the adress of the
5494 and the AS/400 adress).

I tried several variations, but couldn't get the 5494 to connect. On the
operator panel, it gave SRC 460/0 540404.

Any suggestions or tips on this?

Thanx,

Oliver
