Personally, I was just fueling the fire with tongue planted firmly
in-cheek. :-) No offense intended, we tend to pick a lot of nits
'round here.

I'm curious about the chassis designations... isn't the system board
part number more deterministic of the expansion capability than the
chassis? Or is the assumption here that certain chassis types only
carried certain system board revisions (and perhaps extra disk
backplane expansions)?

The reason I bring this up is because during the course of service, I
can say firsthand that zero regard is ever paid to these AA/BA/CA
designations. This would seem somewhat like reading the "SvCd"
markings on the outside edge of a SS5 chassis and assuming the specs
within are correct (i.e., the board was never replaced/upgraded)
without examining the contents.

Just a thought... maybe I'm missing something here.

Thanks,
