Overview

Introduction

The HP Modular Cooling System 200 is an air and water heat exchanger that removes high levels of excess heat generated by equipment installed in HP racks. The installed equipment takes in cold air through the front of the closed MCS-200 and uses the air for internal cooling. After the air has been warmed, the MCS-200 expels the air through the rear vents.

HP provides several components to complement or complete your MCS-200. For more information, see the HP Modular Cooling System 200/100 Options Installation Guide.

IMPORTANT: Before you begin the installation process, review the HP Modular Cooling System

200/100 Site Preparation Guide.

Safety information

The HP Modular Cooling System is tested to the maximum pressure (PS) of 8 bar (116 PSI) without fluid trapped inside by closed, external valves.

If valves are installed on the external pipe work that could potentially trap fluid inside the MCS-200 unit, special precautions must be taken. To prevent severe plumbing failure due to extreme pressure, use an expansion tank with a preinstalled safety valve in the plumbing circuit connected to the unit.

Management module

Management module overview

The HP Modular Cooling System has a management module, which can be accessed remotely through the web interface. The management module analyzes, queries, and manages various measurements and warning and alarm messages from the unit.

The management module (on page 32) analyzes measurements provided by each sensor or module, generates any necessary warning or alarm messages, and then sends them to the web interface. When a new warning or alarm occurs, the warning and alarm messages (on page 45) appear on the operator display as well as on the web interface Alarms menu and Alarm History menu. An alarm relay is also activated (if installed on the unit and enabled in the appropriate web interface menu), and an audible alarm is signaled by the internal beeper (if enabled in the appropriate web interface menu).

The management module performs regulation operations such as:

• Retrieving all measurements from the fan units and the water units in cycles, approximately once per

second (temperature, fan speed, and chilled water flow rate)

• Analyzing all measurements and generated alarm and warning messages

• Calculating heat removed from the water flow rate and temperature of the water supply and return

• Measuring water flow rate

• Regulating the server air inlet temperature by controlling the water flow

• Sending control settings for fan speeds back to the MCS-200 unit

• Sending various system values to the web interface

The web interface displays various measurements and warning and alarm messages (on page 45) from the management module. Also, various system values can be set through the web interface and sent to the management module. For more information about the web interface, see the HP Modular Cooling System Web Interface User Guide.

The following values can be set through the web interface and sent to the management module:

• Server Intake Temperature Set Point—Target value used by the management module for server intake

regulation

• High Temperature Threshold—Temperature difference above Server Intake Temperature Set Point for

temperature-critical alarm message

• Warning Temperature Threshold—Temperature difference above Server Intake Temperature Set Point

for temperature warning message

• Low Temperature Threshold—Temperature difference below Server Intake Temperature Set Point for

temperature warning message

The following values are displayed in the web interface for information only:

• Fan Speed—Displays the fan speed percentage

• Water Valve—Displays the water valve state

Can the level of heat removal be regulated in proportion to the waste heat generated?

How is water connected to the MCS-200 unit?

Can the MCS-200 unit operate with the front or rear door open?

Does the MCS-200 unit require maintenance?

Is a false floor necessary?

Does condensation form?

How does the MCS-200 unit control humidity?

Does the air flow within the MCS-200 unit produce static electricity?

The cooling capacity of the heat exchanger unit depends on the water supply temperature and the server inlet set point. The MCS-200 unit is capable of cooling rack-mounted components consuming up to 50 kW of electrical power.

The water is connected to the unit using a 1.25-inch flexible hose and quick-disconnect automatic shutoff hose fittings. For more information, see the HP Modular Cooling System Hook-Up Kit Installation Instructions.

Yes, due to the air curtain effect, the air will function normally with little air lost. When the doors are open during operation, room air mixes with air supplied to the servers.

No, assuming that the water quality is maintained, the MCS-200 unit is maintenance-free. For more information about water quality, see the HP Modular Cooling System 200/100 Site Preparation Guide on the HP website.

No, a false floor is not necessary to operate the MCS-200 unit. For more information, see the HP Modular Cooling System 200/100 Site Preparation Guide on the HP website.

During normal operation some condensation may form, but the MCS-200 unit condensation control system ensures that the condensation does not reach any rack-mounted components or cause any damage. In most cases, the condensation evaporates prior to reaching the MCS-200 unit condensation control system.

There is some room-air interchange, so the moisture content of the air inside the unit is the same as the room.

Very low humidity levels in the chilled air may produce static electricity. However, static electricity is not a problem if the MCS-200 unit is operated at the specified settings located in the HP Modular Cooling System 200/100 Site Preparation Guide and the Environmental specifications section.

Yes, the MCS-200 unit is physically separate from the server enclosure. Therefore, there is no situation in which water can come directly in contact with the servers. The base unit of each cooling module acts as a condensation tray for water. These trays are connected together, so that any water drains away at once through the condensation drain. Also, each heat exchanger module has a leak and condensation tray that transfers water to the bottom of the MCS-200 unit where it flows to the building condensation return system. If a leak occurs, the integrated leak sensor detects it and an alarm would is issued so that action can be quickly taken.

Maintenance and service

Air and water heat exchanger maintenance

For information on maintenance and service, refer to the HP website (http://www.hp.com).

The air and water heat exchanger requires no maintenance. If particulates are present in the cooling water, a filter must be fitted immediately upstream from the water inlet fittings. Check the functionality of the condensation drainage system regularly. Regularly perform visual inspections for leaks (annually).

Replaceable parts and maintenance and service information 59

Water quality and leveling requirements, and condensation management

Water quality requirements and specifications

Closed-loop water must not contain any lime scale deposits or loose debris. The water must have a low level of hardness, particularly a low level of carbon hardness. Filters must be used to remove free floating particulates and be regularly maintained. Additionally, the water must not be so soft that it attacks the materials with which it comes into contact. You must periodically add new fresh water, but also to remove some enriched water. HP recommends a #30 mesh filter is recommended for filtering water entering the MCS-200 unit and a 1 µm filter for prolonged performance.

Also consider the required set point for the water temperature. Temperatures near or below 0ºC (32ºF) mean that the chilled water plant condenser is very close to or below the freezing point of the water. The chilled water temperature to be supplied to the MCS-200 unit is 5ºC (41ºF). Freezing water can cause a blockage and damage to the unit. Therefore, an additive such as glycol might be necessary to lower the freezing point. However, the heat transfer potential of the water is lower, so the equipment must be derated properly.

In a cooling loop, metallic materials in a pipe distribution network are in constant contact with recirculating liquid and can react with impurities to cause corrosion that can develop into leaks or form deposits and blockages.

The rate of galvanic corrosion depends on the electrical potential between the two dissimilar metals and the temperature of the liquid.

A 10-degree increase in water temperature can double the rate of corrosion. For more information, see the HP Modular Cooling System Site Preparation Guide on the HP website

(http://www.hp.com).

Acceptable water quality specifications

Closed-loop water must not contain any lime scale deposits or loose debris. The water must have a low level of hardness, particularly a low level of carbon hardness. Filters must be used to remove free floating particulates and regularly maintained. The water must not be so soft that it corrodes the materials that it comes into contact. You must periodically add new fresh water, and remove some of the enriched water. HP recommends a #30 mesh filter for filtering water fed to the MCS-200 and a 1 µm filter for prolonged performance.

The following values are water quality ranges required for continuous quality of performance.

Parameter Range

pH Specific conductance at 25ºC (77ºF) Sulfur (SO4), total Chloride (Cl) Sulfide (S)

7-9 <2500 µmhos <100 ppm <50 ppm <10 ppm

Water quality and leveling requirements, and condensation management 60

Parameter Range

Hardness (CaCO3), total Iron (Fe), total Manganese (Mn), total Bacteria Residue on evaporation

Turbidity Corrosion inhibitor

CAUTION: Contaminated water might cause decreased cooling capacity or disruption in

<200 ppm <3.0 ppm <0.1 ppm <1000 CFUs/ml <500 ppm

20 Recommended

service. The water flowing into the MCS-200 unit must meet the guidelines stated in the HP Modular Cooling System Site Preparation Guide. Damage caused by contaminated water is not covered by the MCS unit warranty.

If your water is out of range, consult a water quality expert. HP recommends using particulate filtration on the dedicated water supply system connected to the MCS-200

unit.

Frost damage

To avoid frost damage, the water temperature must not be allowed to fall below the minimum permissible temperature of +4 ºC (+39.2 ºF) at any point in the water cycle.

Before storage or transportation at sub-zero temperatures, the water cycle must be drained completely using compressed air. Avoid setting the target temperature lower than is necessary because the danger of falling below the dew point increases as water temperature decreases (condensation buildup). Ensure that the enclosure is sealed on all sides, and in particular at the cable inlet (condensation formation).

Water precautions

Take the following precautions during the installation of the MCS-200 unit:

• Before installing the HP Modular Cooling System Hook-Up Kit, ensure that all foreign matter and

particulates are flushed from the system.

• Evaluate the short-term and long-term system requirements against the available water capacity.

• Ensure that the chilled water loop is properly designed for liquid cooling systems and is separate from

the sanitary water systems in your building (bathroom, sink, drinking water, and so on).

• Ensure facility managers understand the additional load being added to the chilled water supply of the

building. Be aware that the added heat load might affect other components being cooled by the chilled water plant.

Plumbing materials to avoid

Do not use the following materials in a closed water system:

• Oxidizing biocides

• Aluminum components

• Brass components with high levels of zinc

Water quality and leveling requirements, and condensation management 61

• Non-stainless steel Iron components

Leveling requirements

Adjust the MCS leveling feet so that the unit is level. For more information about seismic area considerations, refer to the HP Modular Cooling System Site

Preparation Guide on the HP website (http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?contentType=SupportManu

al&lang=en&cc=us&docIndexId=64179&taskId=101&prodTypeId=3447589&prodSeriesId=3657806).

Condensation management

Any condensation that forms is collected in each individual cooling module and is taken through a discharge tube to a condensation tray integrated in the base assembly. Where multiple cooling modules are used, the condensate discharge tubes are connected to one another using quick connectors. Any condensation that occurs is then removed through this series of connections to the condensation tray.

When the specified condensation level in the condensation tray is reached, a sensor activates a pump that pumps the condensation into the return system. A further discharge tube runs out of the system from condensation tray to drain excess fluid if needed. This hose should be connected to a collection system or an external drain.

To ensure reliable drainage:

• Ensure no kinks form in the drainage hose.

• Do not reduce diameter of drainage hose.

• Route the drainage hoses so that they always run downhill.

To avoid excessive buildup of condensate and to conserve energy, consider raising the cooling water temperature to the necessary cooling capacity.

Customer Self Repair

HP products are designed with many Customer Self Repair (CSR) parts to minimize repair time and allow for greater flexibility in performing defective parts replacement. If during the diagnosis period HP (or HP service

Support and other resources 63

providers or service partners) identifies that the repair can be accomplished by the use of a CSR part, HP will ship that part directly to you for replacement. There are two categories of CSR parts:

• Mandatory—Parts for which customer self repair is mandatory. If you request HP to replace these parts,

you will be charged for the travel and labor costs of this service.

• Optional—Parts for which customer self repair is optional. These parts are also designed for customer

self repair. If, however, you require that HP replace them for you, there may or may not be additional charges, depending on the type of warranty service designated for your product.

NOTE: Some HP parts are not designed for customer self repair. In order to satisfy the customer warranty, HP requires that an authorized service provider replace the part. These parts are identified as "No" in the Illustrated Parts Catalog.

Based on availability and where geography permits, CSR parts will be shipped for next business day delivery. Same day or four-hour delivery may be offered at an additional charge where geography permits. If assistance is required, you can call the HP Technical Support Center and a technician will help you over the telephone. HP specifies in the materials shipped with a replacement CSR part whether a defective part must be returned to HP. In cases where it is required to return the defective part to HP, you must ship the defective part back to HP within a defined period of time, normally five (5) business days. The defective part must be returned with the associated documentation in the provided shipping material. Failure to return the defective part may result in HP billing you for the replacement. With a customer self repair, HP will pay all shipping and part return costs and determine the courier/carrier to be used.

For more information about HP's Customer Self Repair program, contact your local service provider. For the North American program, refer to the HP website (http://www.hp.com/go/selfrepair).

Réparation par le client (CSR)

Les produits HP comportent de nombreuses pièces CSR (Customer Self Repair = réparation par le client) afin de minimiser les délais de réparation et faciliter le remplacement des pièces défectueuses. Si pendant la période de diagnostic, HP (ou ses partenaires ou mainteneurs agréés) détermine que la réparation peut être effectuée à l'aide d'une pièce CSR, HP vous l'envoie directement. Il existe deux catégories de pièces CSR:

Obligatoire - Pièces pour lesquelles la réparation par le client est obligatoire. Si vous demandez à HP de remplacer ces pièces, les coûts de déplacement et main d'œuvre du service vous seront facturés.

Facultatif - Pièces pour lesquelles la réparation par le client est facultative. Ces pièces sont également conçues pour permettre au client d'effectuer lui-même la réparation. Toutefois, si vous demandez à HP de remplacer ces pièces, l'intervention peut ou non vous être facturée, selon le type de garantie applicable à votre produit.

REMARQUE: Certaines pièces HP ne sont pas conçues pour permettre au client d'effectuer lui-même la réparation. Pour que la garantie puisse s'appliquer, HP exige que le remplacement de la pièce soit effectué par un Mainteneur Agréé. Ces pièces sont identifiées par la mention "Non" dans le Catalogue illustré.

Les pièces CSR sont livrées le jour ouvré suivant, dans la limite des stocks disponibles et selon votre situation géographique. Si votre situation géographique le permet et que vous demandez une livraison le jour même ou dans les 4 heures, celle-ci vous sera facturée. Pour bénéficier d'une assistance téléphonique, appelez le Centre d'assistance technique HP. Dans les documents envoyés avec la pièce de rechange CSR, HP précise s'il est nécessaire de lui retourner la pièce défectueuse. Si c'est le cas, vous devez le faire dans le délai indiqué, généralement cinq (5) jours ouvrés. La pièce et sa documentation doivent être retournées dans l'emballage fourni. Si vous ne retournez pas la pièce défectueuse, HP se réserve le droit de vous facturer les coûts de remplacement. Dans le cas d'une pièce CSR, HP supporte l'ensemble des frais d'expédition et de retour, et détermine la société de courses ou le transporteur à utiliser.

Riparazione da parte del cliente

Per abbreviare i tempi di riparazione e garantire una maggiore flessibilità nella sostituzione di parti difettose, i prodotti HP sono realizzati con numerosi componenti che possono essere riparati direttamente dal cliente (CSR, Customer Self Repair). Se in fase di diagnostica HP (o un centro di servizi o di assistenza HP) identifica il guasto come riparabile mediante un ricambio CSR, HP lo spedirà direttamente al cliente per la sostituzione. Vi sono due categorie di parti CSR:

Obbligatorie – Parti che devono essere necessariamente riparate dal cliente. Se il cliente ne affida la riparazione ad HP, deve sostenere le spese di spedizione e di manodopera per il servizio.

Opzionali – Parti la cui riparazione da parte del cliente è facoltativa. Si tratta comunque di componenti progettati per questo scopo. Se tuttavia il cliente ne richiede la sostituzione ad HP, potrebbe dover sostenere spese addizionali a seconda del tipo di garanzia previsto per il prodotto.

NOTA: alcuni componenti HP non sono progettati per la riparazione da parte del cliente. Per rispettare la garanzia, HP richiede che queste parti siano sostituite da un centro di assistenza autorizzato. Tali parti sono identificate da un "No" nel Catalogo illustrato dei componenti.

In base alla disponibilità e alla località geografica, le parti CSR vengono spedite con consegna entro il giorno lavorativo seguente. La consegna nel giorno stesso o entro quattro ore è offerta con un supplemento di costo solo in alcune zone. In caso di necessità si può richiedere l'assistenza telefonica di un addetto del centro di supporto tecnico HP. Nel materiale fornito con una parte di ricambio CSR, HP specifica se il cliente deve restituire dei componenti. Qualora sia richiesta la resa ad HP del componente difettoso, lo si deve spedire ad HP entro un determinato periodo di tempo, generalmente cinque (5) giorni lavorativi. Il componente difettoso deve essere restituito con la documentazione associata nell'imballo di spedizione fornito. La mancata restituzione del componente può comportare la fatturazione del ricambio da parte di HP. Nel caso di riparazione da parte del cliente, HP sostiene tutte le spese di spedizione e resa e sceglie il corriere/vettore da utilizzare.

Per ulteriori informazioni sul programma CSR di HP contattare il centro di assistenza di zona. Per il programma in Nord America fare riferimento al sito Web HP (http://www.hp.com/go/selfrepair).

Customer Self Repair

HP Produkte enthalten viele CSR-Teile (Customer Self Repair), um Reparaturzeiten zu minimieren und höhere Flexibilität beim Austausch defekter Bauteile zu ermöglichen. Wenn HP (oder ein HP Servicepartner) bei der Diagnose feststellt, dass das Produkt mithilfe eines CSR-Teils repariert werden kann, sendet Ihnen HP dieses Bauteil zum Austausch direkt zu. CSR-Teile werden in zwei Kategorien unterteilt:

Zwingend – Teile, für die das Customer Self Repair-Verfahren zwingend vorgegeben ist. Wenn Sie den Austausch dieser Teile von HP vornehmen lassen, werden Ihnen die Anfahrt- und Arbeitskosten für diesen Service berechnet.

Optional – Teile, für die das Customer Self Repair-Verfahren optional ist. Diese Teile sind auch für Customer Self Repair ausgelegt. Wenn Sie jedoch den Austausch dieser Teile von HP vornehmen lassen möchten, können bei diesem Service je nach den für Ihr Produkt vorgesehenen Garantiebedingungen zusätzliche Kosten anfallen.

Support and other resources 65

HINWEIS: Einige Teile sind nicht für Customer Self Repair ausgelegt. Um den Garantieanspruch des Kunden zu erfüllen, muss das Teil von einem HP Servicepartner ersetzt werden. Im illustrierten Teilekatalog sind diese Teile mit „No“ bzw. „Nein“ gekennzeichnet.

CSR-Teile werden abhängig von der Verfügbarkeit und vom Lieferziel am folgenden Geschäftstag geliefert. Für bestimmte Standorte ist eine Lieferung am selben Tag oder innerhalb von vier Stunden gegen einen Aufpreis verfügbar. Wenn Sie Hilfe benötigen, können Sie das HP technische Support Center anrufen und sich von einem Mitarbeiter per Telefon helfen lassen. Den Materialien, die mit einem CSR-Ersatzteil geliefert werden, können Sie entnehmen, ob das defekte Teil an HP zurückgeschickt werden muss. Wenn es erforderlich ist, das defekte Teil an HP zurückzuschicken, müssen Sie dies innerhalb eines vorgegebenen Zeitraums tun, in der Regel innerhalb von fünf (5) Geschäftstagen. Das defekte Teil muss mit der zugehörigen Dokumentation in der Verpackung zurückgeschickt werden, die im Lieferumfang enthalten ist. Wenn Sie das defekte Teil nicht zurückschicken, kann HP Ihnen das Ersatzteil in Rechnung stellen. Im Falle von Customer Self Repair kommt HP für alle Kosten für die Lieferung und Rücksendung auf und bestimmt den Kurier-/Frachtdienst.

Reparaciones del propio cliente

Los productos de HP incluyen muchos componentes que el propio usuario puede reemplazar (Customer Self Repair, CSR) para minimizar el tiempo de reparación y ofrecer una mayor flexibilidad a la hora de realizar sustituciones de componentes defectuosos. Si, durante la fase de diagnóstico, HP (o los proveedores o socios de servicio de HP) identifica que una reparación puede llevarse a cabo mediante el uso de un componente CSR, HP le enviará dicho componente directamente para que realice su sustitución. Los componentes CSR se clasifican en dos categorías:

• Obligatorio: componentes para los que la reparación por parte del usuario es obligatoria. Si solicita a

HP que realice la sustitución de estos componentes, tendrá que hacerse cargo de los gastos de desplazamiento y de mano de obra de dicho servicio.

• Opcional: componentes para los que la reparación por parte del usuario es opcional. Estos

componentes también están diseñados para que puedan ser reparados por el usuario. Sin embargo, si precisa que HP realice su sustitución, puede o no conllevar costes adicionales, dependiendo del tipo de servicio de garantía correspondiente al producto.

NOTA: Algunos componentes no están diseñados para que puedan ser reparados por el usuario. Para que el usuario haga valer su garantía, HP pone como condición que un proveedor de servicios autorizado realice la sustitución de estos componentes. Dichos componentes se identifican con la palabra "No" en el catálogo ilustrado de componentes.

Según la disponibilidad y la situación geográfica, los componentes CSR se enviarán para que lleguen a su destino al siguiente día laborable. Si la situación geográfica lo permite, se puede solicitar la entrega en el mismo día o en cuatro horas con un coste adicional. Si precisa asistencia técnica, puede llamar al Centro de asistencia técnica de HP y recibirá ayuda telefónica por parte de un técnico. Con el envío de materiales para la sustitución de componentes CSR, HP especificará si los componentes defectuosos deberán devolverse a HP. En aquellos casos en los que sea necesario devolver algún componente a HP, deberá hacerlo en el periodo de tiempo especificado, normalmente cinco días laborables. Los componentes defectuosos deberán devolverse con toda la documentación relacionada y con el embalaje de envío. Si no enviara el componente defectuoso requerido, HP podrá cobrarle por el de sustitución. En el caso de todas

Customer Self Repair

Veel onderdelen in HP producten zijn door de klant zelf te repareren, waardoor de reparatieduur tot een minimum beperkt kan blijven en de flexibiliteit in het vervangen van defecte onderdelen groter is. Deze onderdelen worden CSR-onderdelen (Customer Self Repair) genoemd. Als HP (of een HP Service Partner) bij de diagnose vaststelt dat de reparatie kan worden uitgevoerd met een CSR-onderdeel, verzendt HP dat onderdeel rechtstreeks naar u, zodat u het defecte onderdeel daarmee kunt vervangen. Er zijn twee categorieën CSR-onderdelen:

Verplicht: Onderdelen waarvoor reparatie door de klant verplicht is. Als u HP verzoekt deze onderdelen voor u te vervangen, worden u voor deze service reiskosten en arbeidsloon in rekening gebracht.

Optioneel: Onderdelen waarvoor reparatie door de klant optioneel is. Ook deze onderdelen zijn ontworpen voor reparatie door de klant. Als u echter HP verzoekt deze onderdelen voor u te vervangen, kunnen daarvoor extra kosten in rekening worden gebracht, afhankelijk van het type garantieservice voor het product.

OPMERKING: Sommige HP onderdelen zijn niet ontwikkeld voor reparatie door de klant. In verband met de garantievoorwaarden moet het onderdeel door een geautoriseerde Service Partner worden vervangen. Deze onderdelen worden in de geïllustreerde onderdelencatalogus aangemerkt met "Nee".

Afhankelijk van de leverbaarheid en de locatie worden CSR-onderdelen verzonden voor levering op de eerstvolgende werkdag. Levering op dezelfde dag of binnen vier uur kan tegen meerkosten worden aangeboden, indien dit mogelijk is gezien de locatie. Indien assistentie gewenst is, belt u een HP Service Partner om via de telefoon technische ondersteuning te ontvangen. HP vermeldt in de documentatie bij het vervangende CSR-onderdeel of het defecte onderdeel aan HP moet worden geretourneerd. Als het defecte onderdeel aan HP moet worden teruggezonden, moet u het defecte onderdeel binnen een bepaalde periode, gewoonlijk vijf (5) werkdagen, retourneren aan HP. Het defecte onderdeel moet met de bijbehorende documentatie worden geretourneerd in het meegeleverde verpakkingsmateriaal. Als u het defecte onderdeel niet terugzendt, kan HP u voor het vervangende onderdeel kosten in rekening brengen. Bij reparatie door de klant betaalt HP alle verzendkosten voor het vervangende en geretourneerde onderdeel en kiest HP zelf welke koerier/transportonderneming hiervoor wordt gebruikt.

Neem contact op met een Service Partner voor meer informatie over het Customer Self Repair programma van HP. Informatie over Service Partners vindt u op de HP website (http://www.hp.com/go/selfrepair).

Reparo feito pelo cliente

Os produtos da HP são projetados com muitas peças para reparo feito pelo cliente (CSR) de modo a minimizar o tempo de reparo e permitir maior flexibilidade na substituição de peças com defeito. Se, durante o período de diagnóstico, a HP (ou fornecedores/parceiros de serviço da HP) concluir que o reparo pode ser efetuado pelo uso de uma peça CSR, a peça de reposição será enviada diretamente ao cliente. Existem duas categorias de peças CSR:

Obrigatória – Peças cujo reparo feito pelo cliente é obrigatório. Se desejar que a HP substitua essas peças, serão cobradas as despesas de transporte e mão-de-obra do serviço.

Support and other resources 67

Opcional – Peças cujo reparo feito pelo cliente é opcional. Essas peças também são projetadas para o reparo feito pelo cliente. No entanto, se desejar que a HP as substitua, pode haver ou não a cobrança de taxa adicional, dependendo do tipo de serviço de garantia destinado ao produto.

OBSERVAÇÃO: Algumas peças da HP não são projetadas para o reparo feito pelo cliente. A fim de cumprir a garantia do cliente, a HP exige que um técnico autorizado substitua a peça. Essas peças estão identificadas com a marca "No" (Não), no catálogo de peças ilustrado.

Conforme a disponibilidade e o local geográfico, as peças CSR serão enviadas no primeiro dia útil após o pedido. Onde as condições geográficas permitirem, a entrega no mesmo dia ou em quatro horas pode ser feita mediante uma taxa adicional. Se precisar de auxílio, entre em contato com o Centro de suporte técnico da HP para que um técnico o ajude por telefone. A HP especifica nos materiais fornecidos com a peça CSR de reposição se a peça com defeito deve ser devolvida à HP. Nos casos em que isso for necessário, é preciso enviar a peça com defeito à HP dentro do período determinado, normalmente cinco (5) dias úteis. A peça com defeito deve ser enviada com a documentação correspondente no material de transporte fornecido. Caso não o faça, a HP poderá cobrar a reposição. Para as peças de reparo feito pelo cliente, a HP paga todas as despesas de transporte e de devolução da peça e determina a transportadora/serviço postal a ser utilizado.
