Extend the service life of SN5400 Series infrastructure with renewed NVIDIA business-critical support built around fast hardware recovery. This 56-month term adds long-horizon coverage for organizations that want to keep network operations stable while avoiding the cost and disruption of unmanaged failure events. The 4-hour advanced replacement model is especially valuable in environments where a failed switch cannot wait for standard shipping cycles. It helps shorten the path from incident to recovery, supporting uptime targets across data center, campus, and aggregation deployments. For procurement teams, the longer renewal term improves planning clarity. For operations teams, it provides a support structure that matches the importance of the hardware it protects. This is the kind of coverage that makes sense when the network is too critical for generic support tiers.
