The Cisco Nexus 9500 platform supports up to 10 hot-swappable, front-panel-accessible power supplies. A fully loaded chassis can operate with two 3000W AC power supplies. N+1 and N+N redundancy modes are supported. The 3000W AC power supply is 80 Plus Platinum rated, providing more than 90 percent efficiency across typical workloads.
The additional unused power-supply slots are not needed with existing line cards, but they offer headroom to support higher-bandwidth line cards in the future. Two power supplies are available to provide deployment options:
? N9K-PAC-3000W-B: Cisco Nexus 9500 platform 3000W standard 200-to-240 VAC power supply with port-side intake
? N9K-PUV-3000W-B: Cisco Nexus 9500 platform 3000W universal high-voltage AC/DC power supply with port-side intake
