Which slots must the Supervisor Engine 720 be installed in a 3-slot chassis?

The Supervisor Engine 720 must be installed in specified slots within a 3-slot chassis to ensure proper functionality and operation. In the context of a Cisco 7600 series router, Slot 1 is designated as the primary slot for the Supervisor Engine, while Slot 2 serves as a redundancy or backup option. This setup allows for efficient power management, control of the data traffic, and ensures that the router can maintain operational integrity in case of a failure.

The architecture of these chassis typically limits the Supervisor Engines to these specific slots due to design requirements and to optimize performance. By placing the Supervisor Engine in Slots 1 and 2, the system can properly manage routing processes, maintain high availability, and ensure that all functionalities of the chassis are utilized appropriately.
