I'm in the process of installing some additional ethernet ports into a
2600. Specifically a quad ethernet 4e board. After installing the board and booting the router, I can't see the four interfaces (using show interfaces). I had expected the router to recognize their existence. Is there some configuration that needs to be done for a new card such as this? My router is running IOS 12.2. Sorry if this is obvious, this is a first for me.
