Cisco DPX20/X10 4x10G-BP SR NIC Module, 1-Year | Network Adapter — RD21-4X10GBPSR-1Y

Build fast, compact network attachment into supported DPX20/X10 systems with a pluggable 4 x 10 GbE NIC module. This Cisco SR variant is designed for short-reach fiber environments where links stay within the rack or across nearby equipment, making it a strong fit for tightly packed data center layouts and localized aggregation. Because the module is pluggable, it preserves the platform’s physical efficiency while giving infrastructure teams a clean way to add 10 GbE capacity without redesigning the chassis. That matters when you need to expand port availability, keep cabling straightforward, and maintain consistent performance across a controlled distance. The 1-year coverage is well suited to tactical rollouts, near-term refreshes, or projects where support terms are aligned to a shorter procurement window. For Cisco-standard environments, this module offers a focused path to add bandwidth where short-reach optics are the right technical and financial choice. Ideal For Connecting servers to nearby switches in the same rack Adding 10 GbE capacity to compact data center rows Supporting localized aggregation in Cisco DPX20/X10 environments Deploying short-term expansion where 1-year coverage is sufficient Why This Product 1 SR optics are optimized for short-reach links and intra-rack cabling 2 4-port 10 GbE design adds capacity without increasing chassis footprint 3 Pluggable format keeps deployment simple in supported Cisco systems 4 1-year coverage fits tactical or shorter-cycle procurement plans
