N77-DC-3KW - Cisco NEXUS 7700 - 3.0KW DC POWER SUPPLY MODUL

The Cisco Nexus® 7700 platform switches are the latest extension to the modular Cisco Nexus 7000 Series Switches. The Cisco Nexus 7700 switches have operational and feature consistency with the existing Cisco Nexus 7000 Series Switches, using a common system architecture, the same application-specific integrated circuit (ASIC) technology, and the same proven Cisco® NX-OS Software releases.The Cisco Nexus 7700 AC and DC power supply modules deliver fault tolerance, high efficiency, load sharing, and hot-swappable power features to the Cisco Nexus 7700 switches. The Cisco Nexus 7700 switches use 3.0-kilowatt (kW) power supplies that are 90 percent efficient or greater, so less power is dissipated as heat, and more power is available to the system to use than with typical power supplies. The high-efficiency 3.0-kW power supplies allow a smaller power configuration and provide flexible power provisioning.The maximum output for the 3.0-kW AC power supplies is 1400 or 3000 watts (W) if input power is 110 or 220 VAC respectively, and the dual input 3.0-kW DC power scale is 1500 or 3000W if one or two inputs respectively are active. Both the AC and DC versions support multiple system-level redundancy options for greater availability. Designed to address high-availability requirements, the power supplies incorporate internal component-level monitoring, temperature sensors, and intelligent remote-management capabilities.The power supplies are fully hot swappable, helping ensure no system interruption during installation or upgrades. They are fitted at the bottom front of the Cisco Nexus 7700 chassis, allowing installation and removal without disturbing the network cabling of the I/O modules.
