In search of a table that shows system & O/S release compatibility

I have been searching IBM's Web site to find a table that shows system model (9406-170) and O/S release compatibility. What I'd like to know is if this system will support V5R3, and what the minimum requirements may be? It is currently at V5R2. If you could answer this, or direct me to a Web site that would be great.
The 9406-170 hardware will support an upgrade to V5R3.
