If it is an RK611 (a 9 slot backplane with 5 hex cards in it IIRC), then 
it's for RK06/RK07 drives. The interface is _very_ different to that for 
the RK05.

IIRC (again), the 3 spare slots are one end of the RK611 are wired as SPC 
slots and you can stick normal SPC cards in there (converesly if they're 
empty, you need to put grant continuity cards in them).

Personally, I'd want ot konw why you can't get cards into the exising 
backplane. It may be soemting simple like it's not aligned with the 
cabinet properyl (so the board edge conenctor tabs don't quite line up 
with the backpalne connectors. Try loosening the mouting screws for the 
backplane and sticking a hex card (anything, you're not going to power it 
up) in each end slot, then retighten the screws.
