End-of-life status
The ISR4351-AXV/K9 is end-of-sale
Cisco has declared the ISR4351-AXV/K9 end-of-sale, so it is no longer manufactured new. TFI supplies it professionally refurbished and tested.
Why refurbished still makes sense: a refurbished ISR4351-AXV/K9 delivers the same proven performance at a fraction of the new-equipment cost, backed by a TFI warranty and SLA. It is the practical choice for spares, expansion of an existing deployment, or extending the life of a network you are not ready to replace. Talk to us about a successor model if you are planning a refresh.
