I want to use shelf spare 6500 modules in my 7600 chassis. Can I do it?
for linecards with a DFC submodule the DFC model must be the same as that of the main cpu for example you need DFC 3B if you have SUP 720 3B.
some linecards have older DFC and cannot be upgraded to DFC 3, DFC 3B, DFC 3BXL, DFC 3CXL and so on these modules can be a problem.
Hope to help
