I have 3 CSR's setup and working.  Trying to get netflow to work.  One works just fine but the other two aren't.  Same configuration across the board, destination IP, source interface etc.  The two that don't work look like they are pulling a source ...

Can you swap out the fans and power or do you have to RMA the switch with the proper airflow?

Does anyone know of a good document explaining the pros and cons of using a switch stack and a chassis?Thanks
