Why add Module In Cisco Packet Tracer or in Real Routers?
Sometimes, when creating a topology, we get an error, “This cable can not be connected to that port.” It means that we ran out of available ports and some extra ports are required to make a connection. We will have to add some modules that provide required ports. So before creating a topology, make sure how many ports you will be needing? It is always recommended to have some extra modules for future use.
And always save your configuration before adding any module to your router because you will lose any unsaved configuration if you didn’t save.
Adding Modules in Cisco Packet Tracer:
In some routers, both in real and in CPT, we can add modules to get some extra ports. In Cisco Packet Tracer, to add modules to your Cisco Router, go to Physical Tab and under Modules Tab, you will see the available modules. If you want to add the module, you just have to drag and drop the modules into the available slot.
If the module is compatible, it will be added to the router else you will get an error. Process is same for real router too. Power Off the device, plug in the module in available slot and power on the device.
