Cisco SD-AR1K-SKYF10AB 4x 100GbE QSFP28 | Data Center Switch — SD-AR1K-SKYF10AB

Add 100GbE density where fabric throughput matters most. Cisco SD-AR1K-SKYF10AB provides four QSFP28 ports for high-speed aggregation and spine-style connectivity in environments that need precise component selection rather than bundled hardware. With no software support and no power supply included, it fits deployments where the network team already defines the operating stack, power design, and lifecycle model. This configuration is aimed at infrastructure teams building around existing Cisco standards or integrating into a larger modular system. The four-port 100GbE layout keeps the design focused on uplink capacity and predictable port economics, while the absence of included power hardware supports tailored chassis and power planning. For organizations that buy to exact specifications, this model offers a clean path to match architecture, procurement, and operational requirements without paying for extras that are not needed. Ideal For 100GbE uplink expansion in a data center fabric Aggregation layer deployments requiring four QSFP28 ports Cisco-based modular network builds with separate power planning Infrastructure refreshes where software support is sourced independently Why This Product 1 Four 100GbE QSFP28 ports for focused uplink density 2 Hardware-only build with no software support included 3 No power supply included for custom power architecture 4 Better fit for modular Cisco environments than bundled switch SKUs
