Cisco Nexus 9500R N9K-X9624D-R2= 24 x 400G QSFP-DD | Data Center Switch — N9K-X9624D-R2=

Increase fabric density where throughput and port economics matter most. The Cisco Nexus 9500R Buffer Linecard, MPN N9K-X9624D-R2=, adds 24 x 400G QSFP-DD ports to a Nexus 9500R platform, giving infrastructure teams a direct path to higher aggregate bandwidth in a modular chassis design. This line card is built for large-scale data center switching environments that need to keep east-west traffic moving without forcing a full platform refresh. By concentrating 400G connectivity into a single module, it supports cleaner scaling for spine deployments, high-performance aggregation, and environments where port count, speed, and chassis-based serviceability all matter. For teams standardizing on Cisco Nexus infrastructure, the value is in the architecture: modular expansion, dense 400G uplinks, and a platform approach that preserves investment in the chassis while extending capacity. It is a strong fit when lower-cost fixed switches would create port shortages, cabling complexity, or an earlier replacement cycle. Ideal For Deploy as a high-density spine module in a Cisco Nexus 9500R data center fabric Add 400G uplink capacity to a modular aggregation layer Extend port density in large-scale east-west traffic environments Support chassis-based network growth without replacing the core switching platform Why This Product 1 24 x 400G ports deliver far more density than fixed 100G uplink designs 2 Chassis-based expansion preserves the Nexus 9500R investment 3 QSFP-DD connectivity simplifies high-speed fabric design 4 Buffer linecard architecture suits large east-west traffic environments
