Description
Cisco Nexus N9K-C9408 Modular Switch Chassis
High-Density Enterprise Core/Spine | 8-Slot Expansion Chassis | Cloud Scale Architecture | 4RU Modular Chassis
The Cisco Nexus N9K-C9408 is a high-performance centralized modular switch chassis engineered for compact data center aggregation, core routing, and dense enterprise backbone deployments. Standing at 4 Rack Units (4RU), this innovative modular platform balances space-constrained requirements with substantial scale, offering 8 horizontal expansion slots for Line Expansion Modules (LEMs). Designed with high-velocity port infrastructure in mind, the N9K-C9408 utilizes a backplane-free architecture, enabling superior airflow efficiency, ultra-low latency, and massive data switching capabilities up to 25.6 Tbps. It serves as an optimal evolutionary platform sitting between fixed top-of-rack switches and full-size director chassis.
Key Technical Features
* Centralized Modular Power
Features 8 horizontal expansion bays on a compact 4RU chassis footprint, maximizing high-bandwidth density without excessive rack unit consumption.
* Intelligent Backplane Engineering
Eliminates midplane copper barriers, allowing airflow to move across elements efficiently to drastically simplify system thermal profiles.
* Modular Component Control
Utilizes swappable supervisors and centralized switch cards to guarantee operational continuity and seamless logic upgrades.
* Line-Rate Network Analytics
Embedded Cloud Scale telemetric engines capture network flow statistics directly inside the ASIC layer to power deep management analytics.
* 2+2 Grid Redundancy
Houses up to 4 hot-swappable 2000W high-efficiency power supply modules to split load burdens across active data center grid layers cleanly.
* High-Velocity Cooling Grid
Leverages 5 dedicated hot-swappable vertical fan modules running an intelligent N+1 cooling redundancy program against localized node heat loads.
