Hi Dimitry,
removing of the other cards did not help. The chassis still boots into
PFC3 mode.

I think it could not have helped at all. I am sure mixing of DFC (same
version of PFC) and CFC enabled linecards works.
We have in production other 7606S boxes, with a mix of CFC and DFC cards
and it RUNS in PFC3CXL.
For example this chassis ->

So the setup is almost the same as the chassis in subject.
