The 8200 and 8400 have the 'same' backplane. And, we decide that the
8200 can have 5 slots, the 8400 9. So, on my 8200, what is 'not there'
so to speak, such that I can 'only' plug in 5 boards. I remember
reading some early 8x00 articles that said '6' slots for the 8200.
Where are the 'not there' slots on the 8200 ?
Is this a marketing type decision, or some real engineering differences
? The reason I ask is that for a specific opportunity, a 6 slot 8200
(or a single phase 8400 that list prices at the same) would be just
peachy fine.

The 8400 has a 9-slot centerplane: 5 connectors on one side, and 4 on the other. The 8200 is (conceptually) the same centerplane, but the box in which it sits has no physical space for the boards to plug into the 4 "backside" connectors. And, there is not enough power or cooling in the 8200 box to supply a total of 9 modules. Cheers, Bob | |||||
