Cisco Alteon D-5424/5820 22G to 40G Upgrade | Support, License — L-RD-54-58-22U40=

Scale existing Alteon infrastructure from 22G to 40G with a Cisco upgrade path designed to extend platform life and match rising application demand. For teams managing load balancing and application delivery at the edge, this kind of capacity expansion is often the difference between planned growth and forced refresh. Rather than replacing the platform, this upgrade preserves the installed base while increasing headroom for traffic spikes, service consolidation, and future workload growth. That matters when procurement wants to protect prior investment and operations needs a controlled change window. Because this is a software-services support and warranty item, the value is in continuity: keeping the environment aligned to the supported configuration while avoiding the cost and disruption of a full hardware transition. It is a practical choice for infrastructure teams that need more capacity, not a new architecture. Use it when the current Alteon deployment is still the right platform, but the business has outgrown the original throughput ceiling.
