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 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).
Parts only warranty service
Your HP Limited Warranty may include a parts only warranty service. Under the terms of parts only
warranty service, HP will provide replacement parts free of charge.
For parts only warranty service, CSR part replacement is mandatory. If you request HP to replace these
parts, you will be charged for the travel and labor costs of this service.
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:
Customer self repair 5
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.
Pour plus d'informations sur le programme CSR de HP, contactez votre Mainteneur Agrée local. Pour plus
d'informations sur ce programme en Amérique du Nord, consultez le site Web HP
(http://www.hp.com/go/selfrepair).
Service de garantie "pièces seules"
Votre garantie limitée HP peut inclure un service de garantie "pièces seules". Dans ce cas, les pièces de
rechange fournies par HP ne sont pas facturées.
Dans le cadre de ce service, la réparation des pièces CSR 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.
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.
Customer self repair 6
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).
Servizio di garanzia per i soli componenti
La garanzia limitata HP può includere un servizio di garanzia per i soli componenti. Nei termini di
garanzia del servizio per i soli componenti, HP fornirà gratuitamente le parti di ricambio.
Per il servizio di garanzia per i soli componenti è obbligatoria la formula CSR che prevede la riparazione
da parte del cliente. Se il cliente invece richiede la sostituzione ad HP, dovrà sostenere le spese di
spedizione e di manodopera per il servizio.
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.
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
Customer self repair 7
anrufen und sich von einem Mitarbeiter per Telefon helfen lassen. Den Materialien, die mit einem CSRErsatzteil 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.
Weitere Informationen über das HP Customer Self Repair Programm erhalten Sie von Ihrem Servicepartner
vor Ort. Informationen über das CSR-Programm in Nordamerika finden Sie auf der HP Website unter
(http://www.hp.com/go/selfrepair).
Parts-only Warranty Service (Garantieservice
ausschließlich für Teile)
Ihre HP Garantie umfasst möglicherweise einen Parts-only Warranty Service (Garantieservice
ausschließlich für Teile). Gemäß den Bestimmungen des Parts-only Warranty Service stellt HP Ersatzteile
kostenlos zur Verfügung.
Für den Parts-only Warranty Service ist das CSR-Verfahren zwingend vorgegeben. Wenn Sie den
Austausch dieser Teile von HP vornehmen lassen, werden Ihnen die Anfahrt- und Arbeitskosten für diesen
Service berechnet.
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
Customer self repair 8
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 sustituciones que lleve a cabo el cliente, HP se hará cargo de todos los gastos de envío
y devolución de componentes y escogerá la empresa de transporte que se utilice para dicho servicio.
Para obtener más información acerca del programa de Reparaciones del propio cliente de HP, póngase
en contacto con su proveedor de servicios local. Si está interesado en el programa para Norteamérica,
visite la página web de HP siguiente (http://www.hp.com/go/selfrepair).
Servicio de garantía exclusivo de componentes
La garantía limitada de HP puede que incluya un servicio de garantía exclusivo de componentes. Según
las condiciones de este servicio exclusivo de componentes, HP le facilitará los componentes de repuesto
sin cargo adicional alguno.
Para este servicio de garantía exclusivo de componentes, es obligatoria la sustitución de componentes
por parte del usuario (CSR). 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.
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
Customer self repair 9
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).
Garantieservice "Parts Only"
Het is mogelijk dat de HP garantie alleen de garantieservice "Parts Only" omvat. Volgens de bepalingen
van de Parts Only garantieservice zal HP kosteloos vervangende onderdelen ter beschikking stellen.
Voor de Parts Only garantieservice is vervanging door CSR-onderdelen verplicht. Als u HP verzoekt deze
onderdelen voor u te vervangen, worden u voor deze service reiskosten en arbeidsloon in rekening
gebracht.
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.
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.
Para obter mais informações sobre o programa de reparo feito pelo cliente da HP, entre em contato com
o fornecedor de serviços local. Para o programa norte-americano, visite o site da HP
(http://www.hp.com/go/selfrepair).

Maintenance
Maintenance and service
For information on maintenance and service, refer to the HP website (http://www.hp.com).
Air and water heat exchanger maintenance
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).
Water quality requirements and specifications
Closed-loop water must not contain any lime scale deposits or loose debris. The water should 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. It is necessary to periodically add new fresh water, but also to
remove some enriched water. A #30 mesh filter is recommended for filtering water entering the HP MCS,
and a 1 µm filter is suggested 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 G2 unit is 5ºC (41ºF). Freezing water can cause a
blockage and damage to the unit. So, 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 G2 Site Preparation Guide on the HP website
(http://www.hp.com).

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 HP
Modular Cooling System G2 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 G2 unit:
•
Before installing the HP Modular Cooling System G2 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).
Maintenance
76
•
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
•
Non-stainless steel Iron components
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.
