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. This system provides nomimal -48 VDC service to DC-powered network elements
(NEs) through redundant feeds, complementing the resiliency of Cisco's line of Carrier Class optical
products.

The Cisco AC/DC Power System is designed to be mounted in a variety of rack types including IEC,
ANSI (19 inches), ANSI (23 inches), and ETSI configurations and requires only 177.8mm (7.0in.) of
vertical space for medium and large systems and 133.4mm (5.25in.) for small systems. The system is
based on the CSCO-PWR-RECT rectifier module and allows three different configurations based on
load requirements that range from 13.3A to 96A. Additionally, power distribution is accomplished using
a GMT fuse block and/or an optional 1 RU distribution shelf (depending on system size).

The Cisco AC/DC Power System offers these features:

•

AC input (A) 100-120VAC

•

AC input (B) 200-250VAC

•

Nominal -48 VDC rectifier providing up to 1600W

•

Front access design

•

Temperature hardened -40ºC to +55ºC

•

Available in 19in. (IEC and ANSI), ETSI (21in. inside [610mm]), or 23in. mounting arrangements

•

Available external distribution shelf with up to 4 load circuit breakers

•

10 position GMT fuse panel

•

Active high power factor correction

•

90% or greater efficiency

•

Front panel LCD interface

1.1 System Description

This section provides descriptions of the system shelf, rectifier modules, GMT fuses, and the 1 RU
distribution shelf.
