The WS-F6K-DFC is only supported on the sup2. See

You need a DFC3 to work with the sup720. If the line card supports it,
you probably want a WS-F6700-DFC3B.

Which brings up another question for me: Can you use any of the DFC3s
(WS-F6700-DFC3B, WS-F6700-DFC3A, WS-F6700-DFC3BXL) on any line card that
supports DFC3s?
