Description
Cisco Nexus N9K-C9504 Modular Switch Chassis
Compact Data Center Core/Spine | 4 Line Card Slots | Cloud Scale Architecture | 7RU Modular Chassis
The Cisco Nexus N9K-C9504 is a compact, high-performance modular director chassis optimized for space-constrained data center core, spine, and aggregation layers. Standing at 7 Rack Units (7RU), this highly resilient platform features 4 horizontal line card slots capable of scaling across 1G through 400G deployments. Built for enterprise cloud-scale environments, the N9K-C9504 utilizes a specialized backplane-free design where fabric modules interface directly with line cards. This design eliminates physical midplane copper bottlenecks, maximizing airflow efficiency while ensuring massive investment protection, ultra-low latency, and market-leading network telemetry.
Key Technical Features
* Compact Form Factor Density
Features 4 line card slots supporting up to 192 native 10/25G SFP ports, 144 40/100G QSFP ports, or up to 64 ultra-dense 400G QSFP-DD ports.
* Backplane-Free Innovation
Line cards connect directly to vertical fabric modules via orthogonal connectors, radically improving airflow efficiency and switching performance.
* Enterprise Redundancy
Supports up to 2 dedicated supervisor modules, up to 6 rear fabric modules, and up to 3 multi-rotor fan trays for full N+1 infrastructure resiliency.
* Cloud Scale Telemetry
Hardware-embedded ASIC capabilities stream line-rate flow logs and packet statistics without impacting CPU control plane performance bounds.
* Efficient Power Grid
Houses up to 4 hot-swappable 3000W high-efficiency power supply units (PSUs), enabling flexible grid redundancy configurations across high-load operations.
* Flexible Optical Architecture
Accepts both multi-rate transceivers and active/passive direct-attach copper breakout cables to adapt effortlessly into heterogeneous environments.
