What is the purpose of service modules in these 4000 router series?

 Hi there,

The slots on the ISR4000 can be used for either NIMs or SM-X modules which provide a variety of new functionality to the chassis. An exhaustive list can be found here:

Is there a feature that you are looking for?

cheers,

Seb.
