Resolution
The Supervisor Engine 720 (Sup 720) must be installed in particular slots in the 3-, 6-, 9-, and 13-slot chassis because the switch fabric is integrated with the supervisor. For slot requirements, refer to Table A:
Table A. Supervisor Engine 720 Slot Requirements
Chassis | Slots for Supervisor Engine 720 |
6503/6503-E/7603 | 1 or 2 |
6506/6506-E/7606 | 5 or 6 |
