Customer self repair 6 C us tomer se lf r epair HP products are designed with many Customer Self Repair (CSR) parts to minimi ze repair time and allow for greater flexibility in performing def ective parts re placement. If during the di agnosis period HP (or HP service providers or service partners) iden tifies that the repair can be accomplished by the use of a CSR part, HP will ship that part directly to you for re placement. There are two categories of CSR parts: • Mandatory —Parts for wh ich customer self repair is man datory. 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 op tional. 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 prov ider 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 shippe d for next business day delivery. Same day or four-hour delivery may be offered at an additi onal 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 mate rials shipped with a replacem ent CSR part whether a defective part must be returned to HP. In cases wh ere it is required to return the defective part to HP, you must ship the defective part back to HP within a defi ned period of time, normally five (5) business days. The defective part must be returned with the associat ed documentation in the provided shipping material. Failure to return the defectiv e 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.

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 re placement parts free of charge. For parts only warranty service, CSR part replacement is mandatory. If you requ est HP to replace these parts, you will be charged for the travel and labor costs of this service. Répar ati on par le c lie nt (C SR) Les produits HP comportent de no mbreuses pièces CSR (Customer Self Repair = réparation par le client) afin de minimiser les délais de répar ation et faciliter le remplacement des pièces défectueuses. Si pendant la période de diagnostic, HP (ou se s partenaires ou mainteneurs agréés) détermine que la réparation peut être effectuée à l'aide d'une pièce CSR, HP vous l'envo ie directement. Il existe deux catégorie s de pièces CSR:
Customer self repair 7 • Obligatoire - Pièces pour lesquelles la réparation par le client est obligatoire. Si vous demandez à HP de remplacer ces pièces, les coûts de déplac ement 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'effect uer lui-même la r éparation. Toutefoi s, 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.

Dans les do cuments envoyés avec la pièc e de rechange CSR, HP précise s'il est nécessaire de lui re tourner la pièc e défectueuse . Si c'est le cas, vous devez le faire dans le délai indiqué, généralement ci nq (5) jours ouvrés. La pièce et sa documentation doivent être retournées dans l'emballage fourni. Si vo us ne retournez pas la pi èce défectueuse, HP se réserve le droit de vous fa cturer les coûts de remp lacement.

Dans le cadre de ce service, la ré paration des pièces CSR par le client est obligatoire. Si vous demandez à HP de remplacer ces pièces, les coûts de déplacemen t et main d'œuvre du servi ce vous seront facturés. R ipar a zi one da par te del c lien te Per abbreviare i tempi di riparazione e garantire una maggiore flessibilità nella sostituzione di parti difettose, i prodotti HP sono realiz zati con numerosi componenti che possono essere riparati direttamente dal cliente (CSR, Customer Self Repai r). Se in fase di diagnostica HP (o un centro di servizi o di assistenza HP) identifica il guasto come riparabile me diante un ricambio CSR, HP lo spedirà direttamente al cliente per la sostituzion e. Vi sono due categorie di parti CSR: • Obbligatorie – Parti che devono essere necessariamente ri parate dal cliente. Se il cliente ne affida la riparazione ad HP, deve sostenere le spese di spedizione e di manodo pera per il servizio. • Opzionali – Parti la cui riparazione da parte del clie nte è facoltativa. Si tratta comu nque di componenti progettati per questo scopo. Se tuttavia il cliente ne richiede la sostit uzione ad HP, potrebbe dover sostenere spese addizionali a seconda del tipo di garanzia pr evisto per il prodotto.
Customer self repair 8 NOTA: alcuni componenti HP non sono progettati per la ri parazione da parte del cl iente. Pe r rispettare la garanzia, HP richiede che queste parti siano sostituite da un c entro di assistenza autorizzato. Tali parti sono identificate da un "No" nel Ca talogo 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 restit uire dei componenti . Qualora sia richiesta la resa ad HP del c omponente difettoso, lo si deve spedire ad HP entro un determinato periodo di temp o, generalmente cinque (5) giorni lavorativi. Il componente difettoso deve essere restituito c on la documentazione associata nell'imballo di spedizione fornito. La mancata restituz ione del comp onente può comportare la fatturazione del ricambio da parte di HP.

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 sostituzion e ad HP, dovrà sostenere le spese di spedizione e di manodopera per il servizio.

Maintenance 139 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 mainte nance. If particulates are present in the cooling water, a filter must be fitted. Check the function in g of the condensation drainage system regularly. Regularly perform visual insp ections for leaks (annually) . Water quality CAUTION: Damage caused by water that does not meet the HP Modular Cooling System water quality requirements is not covered by MCS warranty. For specific guidelines con cerning water quality, see the HP Modular Cooling System Site Preparation Guide . Condensation management Any condensation that forms is colle cted 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 tub es are conne cted to one another using quick connectors. Any condensation that occurs is then remov ed through th is series of connecti ons to the condensation tray. When the specified condensation level in the condensa tion 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 conn ected 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 co nserve energy, consider raising the cooling water temperature to the necessary cool ing capacity. Frost damage To avoid frost damage, the water temperature must no t be allowed to fall below the minimum permissible temperature of 4 ºC ( 39.2 ºF) at any point in the water cy cle.
Maintenance 140 Before storage or transportation at sub-zero temper atures, the water cycle must be drained completely using compressed air. Avoi d setting the target temper atur e low er than is ne cess ary because the danger of falling below the dew point increases as water temper ature decreases (condensation buildup). Ensure that the enclosure is sealed on all sides, and in particular at the cable inlet (condensation formation). Diagnostic tools For a complete list of the warning and alarm messa ges displayed on the operator display and the web interface, see the HP Modular Coolin g System User Guide , included with your original MCS unit .
