Why refurbished still makes sense: a refurbished Cisco2851-SEC/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.
