Cisco DPX20/X10 Pluggable 4x10G NIC Module | Enterprise Adapter — RD21-4X10GNIC-5Y

Add controlled network capacity to DPX20/X10 systems with a pluggable 4x10G NIC module built for supported Cisco environments. This module is a strong fit when teams need to increase port density without moving to a larger architecture, keeping upgrades focused, predictable, and easier to validate during rollout. Four 10 GbE connections provide a practical balance of bandwidth and flexibility for access, aggregation, and application traffic. The pluggable design supports straightforward integration into compatible hardware, while the 5-year term gives procurement and operations teams a longer planning horizon. That matters when refresh schedules, support alignment, and budget timing all need to stay in sync. Compared with generic adapters, this module is easier to justify in standardized Cisco deployments because it is tied to the intended platform and use pattern. The result is less guesswork during qualification, cleaner inventory decisions, and a more durable fit for organizations that value consistency across infrastructure layers.
