The Cisco AC/DC Power Solution provides a scalable platform for the delivery of DC power to equipment-installation sites that have only an AC power source.
PRODUCT OVERVIEW
The Cisco® AC/DC Power Solution is a rack-mounted AC-to-DC power system that provides a compact, scalable solution for powering Cisco optical platforms at site locations with only AC power available. The system accepts AC inputs and converts them to nominal -48 VDC for DC-powered equipment. The Cisco AC/DC Power Solution is available in three configurations (Figures 1, 2, and 3) to accommodate various equipment loads up to 96 amperes (96A) at nominal -48 VDC. This compact system provides N+1 redundancy in rectifiers, automated alarm generation, and integrated DC power distribution through a GMT-type fuse panel or circuit breakers, for powering up to five DC-powered network elements with redundant feeds, complementing the resiliency of Cisco carrier-class optical products.

Large Configuration of Cisco AC/DC Power Solution
The Cisco AC/DC Power Solution can be mounted in a variety of rack types including IEC, ANSI 19-inch, ANSI 23-inch, and ETSI configurations and requires only 5.25-inch (133.4 millimeters [mm]) or 7.0-inch (177.8 mm) of vertical rack space for the small and medium-to-large configurations, respectively. The systems employ rectifier modules in an N+1 load-sharing configuration, each with universal AC input capability, and are shipped with country-specific AC input cables. If user DC power requirements increase in the future, the system scales, in service, from small to medium to large by the simple addition of slide-in rectifier modules and an external distribution panel, providing an economical, simple growth path.
APPLICATIONS
The Cisco AC/DC Power Solution is designed to power equipment requiring nominal -48 VDC input. The solution has been successfully tested with Cisco optical products, including the Cisco ONS 15454 SDH/SONET Multiservice Provisioning Platform, Cisco ONS 15327 SONET Multiservice Platform, and the Cisco ONS 15302 and Cisco ONS 15305 Multiservice Customer Access Platforms. Table 1 outlines typical applications for the solution sizes of the Cisco AC/DC Power Solution.
