    Introduction The Cisco AC/DC Power System is a rack-mounted, AC-to-DC power system that provides a scalable, compact solution for powering 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. This compact system provides N+1 redundancy in rectifiers, automated alarm generation, and integrated DC power distribution through a GMT fuse panel and available four-position 1RU circuit breaker distribution shelf.

  • Page 18: System Shelf

    1.1.1 System Shelf 1.1.1 System Shelf The AC/DC power system shelf consists of four rectifier slots and system monitoring/control interfaces. The system controller provides rectifier monitoring, operational data collection, alarm generation, and intra-system communications regulation. Figure 1-1 Cisco AC/DC Power System (with Optional 1RU DC Distribution Shelf) There are two system shelves, one of which has an LCD display on the front of the shelf.
