IBM AIX on AS/400 Systems

Sry for my beginner question. I didn't find a list with all supported server types for an AIX 5.3 installation. Unfortunately ibm.com page has problems with the sign in so I can't ask in the ibm foum. Will AIX 5.3 run on a 9402, 9404 or 9406 system? Thanks for your help.

we need more info on the AS400 to answer that.
the 940x is the machine type, there is also a model number: 940x-yyy.
if the yyy starts with a 5 then you can run AIX on a partition.
apart from looking on the front of the machine for the machine type and model I can't help with an OS400 command to tell you the model.

Thank you for the answer. It's an 9402-400 system.

nope, that model cannot run AIX
