Cisco VIP4-50 enterprise networking (router/Catalyst switch/UCS families) Router Line Card

The Cisco VIP4-50 is a Versatile Interface Processor 4 (VIP4), Model 50, for the Cisco 7500 Series router family. Like the higher-specification VIP4-80, it is a distributed-processing interface card carrying its own onboard CPU and forwarding logic, letting a 7500 chassis scale total forwarding performance by spreading work across several interface processors rather than relying solely on the central Route Switch Processor. The Model 50 sits below the Model 80 in the VIP4 range, suited to 7500 deployments with lower port-density or throughput requirements than the top-end configuration needs. It remains a routine spare for existing 7500-series routers still in service, restoring interface capacity or replacing a failed VIP. Confirm your RSP generation and required IOS feature set before ordering, since VIP4 compatibility depends on the router’s software train. This is a refurbished unit, shipped worldwide from Tech-Star’s UK stock.
