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 op erate the product.

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

4.2 General Information

The Power Control System (XCS) (Figure 4-1) is a supervisory system that is designed to control AC/DC power systems that are based on XR1648 rectifier modules.

Communication is accomplished through an alarm interface board and a backplane that connects to the rectifier modules.

4.2.1 Alarm Interface Board and Connections

The alarm interface board is the main connection point for external communication inputs. The board is located inside the controller and can be accessed by removing the front controller cover and then sliding out the controller tray to expose the alarm connections (located on the right-hand side).

Alarm connections are made at the terminal block located on the Alarm/Interface PC board. The green connectors can be easily removed for ease in installing the wires into the connector; 22 AWG (0.34mm²) wire is recommended for connecting alarms to the alarm output terminals (Figure 2-21 on page 2-24). External connections are Form C relay which can be monitored either Normally Closed or Normally Open. The four alarms are numbered 1 through 4. (Refer to Table 2-6 on page 2-23).

Note All alarm connections are for the unpowered state. When the power is off the NC is normally closed and

when the power is on, the NC is open.

The following is a list of alarm board connections including descriptions and cabling:

• Alarms - Up to four Form C alarm contacts for remote signaling

• Load fuse and breaker monitoring

• RS232 Interface - External communications port (not utilized in this application)

Chapter 4 System Operation

4.2.2 Basic Controller Functions

The following section contains basic controller functions including starting the controller, adding modules, and removing modules from the system.

4.2.2.1 Start the Controller

When power is applied to the controller:

Step 1 The controller will spend several minutes analyzing the system and testing all addresses for connected

rectifier modules. The green LED on the controller will blink. No alarms will be raised during this period.

Step 2 When the controller finds a module it will add it to the inventory.

4.2.2.2 Add Modules

When a rectifier is added to the system it will remain off until the controller detects it.

Step 1 When a rectifier is added to the system, its output voltage will walk-in, increasing up to its default

setting. This will occur within 60 seconds.

Step 2 The controller constantly scans for new modules, but it may take a few minutes to recognize an inserted

module.

4-2

Cisco AC/DC Power System User Guide, R1.0

May 2006

Chapter 4 System Operation

Step 3 During this recognition time the controller may report module-related alarms and the red LED on the

rectifier may turn on. These alarms are caused by imbalances related to load sharing of the rectifiers (the new rectifier’s output voltage is different than the existing rectifiers).

Step 4 The rectifier module will take a few minutes to step up to the correct voltage. At this point the controller

will locate and adjust the rectifier module voltage to the correct output voltage and any alarms will be extinguished.

Step 5 To shorten the time that is needed to find new modules, the controller can be powered down and then

powered up. This will cause the system to search for new modules faster. This is only recommended as a solution if it is important to shorten the time required for searching for new modules.

4.2.2.3 Remove Modules

Physically removing a module from the system creates a communication error indicated by the yellow LED on the controller. The yellow LED will remain on until a rectifier is installed.

Varoitus

Attention

Warnung

Avvertenza

Statement 43

Alvorens aan apparatuur te werken die met elektrische leidingen is verbonden, sieraden (inclusief ringen, kettingen en horloges) verwijderen. Metalen voorwerpen worden warm wanneer ze met stroom en aarde zijn verbonden, en kunnen ernstige brandwonden veroorzaken of het metalen voorwerp aan de aansluitklemmen lassen.

Ennen kuin työskentelet voimavirtajohtoihin kytkettyjen laitteiden parissa, ota pois kaikki korut (sormukset, kaulakorut ja kellot mukaan lukien). Metalliesineet kuumenevat, kun ne ovat yhteydessä sähkövirran ja maan kanssa, ja ne voivat aiheuttaa vakavia palovammoja tai hitsata metalliesineet kiinni liitäntänapoihin.

Avant d’accéder à cet équipement connecté aux lignes électriques, ôter tout bijou (anneaux, colliers et montres compris). Lorsqu’ils sont branchés à l’alimentation et reliés à la terre, les objets métalliques chauffent, ce qui peut provoquer des blessures graves ou souder l’objet métallique aux bornes.

Vor der Arbeit an Geräten, die an das Netz angeschlossen sind, jeglichen Schmuck (einschließlich Ringe, Ketten und Uhren) abnehmen. Metallgegenstände erhitzen sich, wenn sie an das Netz und die Erde angeschlossen werden, und können schwere Verbrennungen verursachen oder an die Anschlußklemmen angeschweißt werden.

Prima di intervenire su apparecchiature collegate alle linee di alimentazione, togliersi qualsiasi monile (inclusi anelli, collane, braccialetti ed orologi). Gli oggetti metallici si riscaldano quando sono collegati tra punti di alimentazione e massa: possono causare ustioni gravi oppure il metallo può saldarsi ai terminali.

¡Advertencia!

Advarsel

Aviso

Varning!

Fjern alle smykker (inkludert ringer, halskjeder og klokker) før du skal arbeide på utstyr som er koblet til kraftledninger. Metallgjenstander som er koblet til kraftledninger og jord blir svært varme og kan forårsake alvorlige brannskader eller smelte fast til polene.

Antes de trabalhar em equipamento que esteja ligado a linhas de corrente, retire todas as jóias que estiver a usar (incluindo anéis, fios e relógios). Os objectos metálicos aquecerão em contacto com a corrente e em contacto com a ligação à terra, podendo causar queimaduras graves ou ficarem soldados aos terminais.

Antes de operar sobre equipos conectados a líneas de alimentación, quitarse las joyas (incluidos anillos, collares y relojes). Los objetos de metal se calientan cuando se conectan a la alimentación y a tierra, lo que puede ocasionar quemaduras graves o que los objetos metálicos queden soldados a los bornes.

Tag av alla smycken (inklusive ringar, halsband och armbandsur) innan du arbetar på utrustning som är kopplad till kraftledningar. Metallobjekt hettas upp när de kopplas ihop med ström och jord och kan förorsaka allvarliga brännskador; metallobjekt kan också sammansvetsas med kontakterna.
