The port-side exhaust design helps optimize airflow within crowded rack environments, minimizing thermal hotspots and sustaining performance even in hot, busy data centers. If you're upgrading, expanding, or deploying a new Nexus 9000 system, this power supply is engineered to maximize uptime, simplify maintenance, and support enterprise-grade availability.

• High-capacity 350 W AC power supply tailored for Cisco Nexus 9000 switches, providing ample headroom for peak traffic, virtualization, and fluctuating workloads.
• Port-side exhaust design that channels warm air away from critical components, enhancing rack airflow and reducing thermal buildup in densely packed data centers.
• Global input compatibility with 120 V AC or 230 V AC (50/60 Hz), allowing easy deployment across regions without multiple power configurations.
• Hot-swappable, field-replaceable PSU to minimize downtime; swap components without powering down the switch and keep critical services online.
• Cisco-certified hardware with proven compatibility across the Nexus 9000 family, backed by Cisco support, warranty options, and a robust ecosystem of updates and service.

In modern data centers, power delivery and thermal management are as critical as the data path itself. The Nexus 9000 350W AC PS is engineered to deliver steady, predictable power to support high-throughput environments, including spine-leaf architectures and multi-chassis interconnects. The 350-watt rating provides comfortable margin during peak uplink activity, large-scale virtualization, and bursts in web-scale or enterprise workloads. The port-side exhaust, a key feature of this PSU, aligns with common front-to-back cooling strategies used in many Cisco deployments, helping maintain a balanced airflow in 42U or taller racks. This results in cooler intake for adjacent components and more consistent performance across all active modules in the switch chassis.

Designed for reliability, this power supply adheres to Cisco’s strict hardware standards and quality controls. It is built to operate in demanding data-center conditions, with attention to thermal management, mechanical fit, and ease of replacement. The hot-swappable design minimizes maintenance windows, enabling IT teams to perform routine swaps, part replacements, or upgrades with minimal disruption. For organizations pursuing high availability, pairing this PSU with redundant units can support N+R or N+N configurations, providing failover protection for critical network operations. Simply put, the Nexus 9000 350W AC PS helps you maintain uptime while delivering the robust performance expected from Cisco’s Nexus platform.

Beyond raw power, administrators will appreciate the PSU’s compatibility with the broader Nexus ecosystem. The module is designed to slide into the dedicated PSU bay of compatible Nexus 9000 switches, aligning with Cisco’s installation guidelines for safe handling and proper engagement with the chassis connectors. The port-side exhaust aligns with many data-center rack layouts, allowing operators to design cooling strategies around this airflow direction to optimize overall energy use and temperature control. This is particularly valuable in dense environments where every watt of power and every cubic foot of cooling matters for operating cost efficiency and service levels. Whether you’re outfitting a new build or refreshing existing infrastructure, the 350W AC PSU for Nexus 9000 is a dependable choice for consistent performance and long-term operational stability.

To maximize value, consider the power supply as part of a holistic approach to Nexus 9000 deployment, including appropriate fan configurations, power distribution, and preventive maintenance. Cisco’s certified hardware and common stocking of replacement units simplify procurement and service, helping IT teams keep their networks online. The combination of 350W capacity, dual-voltage input, port-side exhaust, and hot-swappability makes this PSU a practical and future-proof component for data centers seeking scalable, resilient networking with the Cisco Nexus 9000 series.
