Hi Yousef,
As per the documentation
Slot 7 is reserved for the supervisor engine. Please try to put it in different slots as suggested by below document.
If a redundant supervisor engine is not required, slots 1 through 6 and slots 8 through 13 are available for modules.
Please go through the following notes :
All Catalyst 6500 series switches and Cisco 7600 series routers support hot swapping, allowing you to install, remove, and replace modules without turning off chassis power. For more information on removing the modules from a switch, see the "Removing a Module" section.
When the software detects that a module has been installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the module, and resumes switch operation.
The Catalyst 6503-E switch, Cisco 7603 router, or Cisco 7603-S router chassis has three horizontal slots. The Catalyst 6504-E switch, Cisco 7604 router, or Cisco 7604-S router chassis has four horizontal slots. In these chassis, the slots can be used as follows:
•
Slot 1, the top-most slot, is reserved for the supervisor engine.
•Slot 2 can be used for a redundant supervisor engine.
•If a redundant supervisor engine is not required, the following slots are available for modules:
–Slots 2 and 3 on the 3-slot chassis
–Slots 2 through 4 on the 4-slot chassis
•Empty slots require filler panels to maintain consistent airflow through the chassis.
The Catalyst 6509-V-E switch, the Cisco 7609 router, or the Cisco 7609-S router chassis has nine vertical slots, which are numbered 1 to 9 from right to left. Install vertical modules with the component side facing to the right. In these chassis, the slots can be used as follows:
•Slot 5 is reserved for the supervisor engine.
•Slot 6 can be used for a redundant supervisor engine.
•If a redundant supervisor engine is not required, the following slots are available for modules:
–Slots 1 through 4 and slot 6 on the 6-slot chassis
–Slots 1 through 4 and slots 6 through 9 on the 9-slot chassis
•Empty slots require filler panels to maintain consistent airflow through the switch chassis.
The Catalyst 6513 switch or Cisco 7613 router chassis has 13 horizontal slots. In these chassis, the slots can be used as follows:
•Slot 7 is reserved for the supervisor engine.
•Slot 8 can be used for a redundant supervisor engine.
•If a redundant supervisor engine is not required, slots 1 through 6 and slots 8 through 13 are available for modules.
•Empty slots require filler panels to maintain consistent airflow through the chassis.
