Cisco Nexus 7000 3.0-kW and 6.0-kW DC Power Supply Modules offer features that are designed to make operation of a DC environment simpler and reduce operating costs through common sparing, hot-swappable features, and higher efficiency. The Cisco Nexus 7000 Series also supports multiple power redundancy schemes, mixed-mode AC and DC operations, and real-time power information. The following list presents the main features:

Common power supply across the Cisco Nexus 7000 9-, 10-, and 18-Slot Switches and Cisco Nexus 7000 Series systems for common sparing flexibility (6.0-kW DC power supply only)

Efficiency greater than 91 percent, reducing power losses from conversion

Hot-swappable power supplies for upgrades or maintenance with no service disruption

Mixed-mode AC and DC operation, enabling migration without disruption and providing support for dual environments with unreliable AC power, with battery backup capability

Equally sized, multiple inputs, reducing fusing requirements and maintaining a consistent supply wire gauge for all output configurations, avoiding the need for costly upgrades.
