THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

•Turn the television or radio antenna until the interference stops.

•Move the equipment to one side or the other of the television or radio.

•Move the equipment farther away from the television or radio.

•Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

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
