Safety Instructions

Use the following safety guidelines to ensure your own personal safety and to help protect your system and working environment from potential damage. For complete safety and regulatory information, see the Product Information Guide that shipped with your system. Warranty information might be included in this document or as a separate document.

SAFETY: Rack Mounting of Systems

Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation accompanying the system and the rack for specific caution statements and procedures.

Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various peripherals or supporting hardware.

a rack could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizer(s) before installing components in the rack.

After installing system/components in a rack, never pull more than one component out of the rack on its slide assemblies at one time. The weight of more than one extended component could cause the rack to tip over and may result in serious injury.

NOTE: Your system is safety-certified as a free-standing unit and as a component for use in a Dell rack cabinet using the customer rack kit. The installation of your system and rack kit in any other rack cabinet has not been approved by any safety agencies. It is your responsibility to ensure that the final combination of system and rack complies with all applicable safety standards and local electric code requirements. Dell disclaims all liability and warranties in connection with such combinations.

•System rack kits are intended to be installed in a rack by trained service technicians. If you install the kit in any other rack, be sure that the rack meets the specifications of a Dell rack.

CAUTION: Do not move racks by yourself. Due to the height and weight of the rack, a minimum of two people should accomplish this task.

•Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack.

•Always load the rack from the bottom up, and load the heaviest item in the rack first.

•Make sure that the rack is level and stable before extending a component from the rack.

•Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the slide rails can pinch your fingers.

•Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating.

•Ensure that proper airflow is provided to components in the rack.

•Do not step on or stand on any component when servicing other components in a rack.

Rack Installation Guide		5

General Installation Instructions

This installation guide provides instructions for trained service technicians installing one or more systems in a rack cabinet. The RapidRails™ configuration can be installed without tools in manufacturer's rack cabinets that have square holes; the VersaRails™ configuration can be installed in most industry-standard rack cabinets that have square or round holes. One rack kit is required for each system to be installed in the rack cabinet.

Before You Begin

Before you begin installing your system in the rack, carefully read "Safety Instructions" on page 5, as well as the safety instructions found in your Product Information Guide for additional information.

CAUTION: When installing multiple systems in a rack, complete all of the procedures for the current system before attempting to install the next system.

CAUTION: Rack cabinets can be extremely heavy and move easily on their casters. They do not have brakes. Use extreme caution while moving the rack cabinet. Retract the leveling feet when relocating the rack cabinet. Avoid long or steep inclines or ramps where loss of cabinet control may occur. Extend the leveling feet for support and to prevent the cabinet from rolling.

NOTE: For instructions on installing the system itself, see "Installing the System in the Rack" on page 15.

Important Safety Information

Observe the safety precautions in the following subsections when installing your system in the rack.

CAUTION: You must strictly follow the procedures in this document to protect yourself as well as others who may be involved. Your system may be very large and heavy and proper preparation and planning are important to prevent injury to yourself and to others. This precaution becomes increasingly important when systems are installed high up in the rack.

CAUTION: Do not install rack kit components designed for another system. Use only the rack kit for your system. Using the rack kit for another system may result in damage to the system and personal injury to yourself and to others.

Rack Requirements for VersaRails

NOTICE: The VersaRails rack kit is intended to be installed by trained service technicians in a rack that meets the specifications of American National Standards Institute (ANSI)/Electronic Industries Association (EIA) standard ANSI/EIA-310-D-92, International Electrotechnical Commission (IEC) 297, and Deutsche Industrie Norm (DIN) 41494. One rack kit is required for each system that is installed in a rack.

6 Rack Installation Guide

Rack Stabilizer Feet

CAUTION: Before installing systems in a rack, install front and side stabilizers on stand-alone racks or the front stabilizer on racks joined to other racks. Failure to install stabilizers accordingly before installing systems in a rack could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizer(s) before installing components in the rack.

The stabilizer feet help prevent the rack from tipping over. See the documentation provided with the rack cabinet for instructions on installing and anchoring the stabilizer feet.

Recommended Tools and Supplies

You may need the following items to install the system in a four-post rack cabinet:

•#2 Phillips screwdriver

•Masking tape or a felt-tip pen, for use in marking the mounting holes to be used

Rack Kit Contents

•One pair of slide assemblies

•One cable-management arm

•One left cable-management arm ramp assembly

•One right cable-management arm ramp assembly

•One status indicator cable (if applicable)

•Eight 10-32 x 0.5-inch flange-head Phillips screws

NOTE: The nonmetric screws described in illustrations and in procedural steps are identified by size and number of threads per inch. For example, a #10 Phillips-head screw with 32 threads per inch is identified as a 10-32 screw.

NOTE: Both the right and left cable-management arm ramp assemblies are illustrated in Figure 1-1. Depending on the orientation of the cable-management arm (CMA), you will only use one ramp assembly to secure the CMA to the back of the rack. For more information, see "Attaching the Cable-Management Arm Ramp Assembly"

8 Rack Installation Guide

Removing the Rack Doors

See the procedures for removing doors in the documentation provided with your rack cabinet.

CAUTION: Because of the size and weight of the rack cabinet doors, never attempt to remove or install them by yourself.

CAUTION: Store the doors where they will not injure someone if the doors accidently fall over.

Marking the Rack

For a 2-U system, you must allow 2 U (88 mm, or 3.5 inches) of vertical space for each system you install in the rack.

Rack cabinets that meet EIA-310 standards have an alternating pattern of three holes per rack unit with center-to-center hole spacing (beginning at the top hole of a 1-U space) of 15.9 mm, 15.9 mm, and 12.7 mm (0.625 inch, 0.625 inch, and 0.5 inch) for the front and back vertical rails (see Figure 1-2). Rack cabinets may have round or square holes.

NOTE: The vertical rails may be marked by horizontal lines and numbers in 1-U increments. If you want, you can make a note of the number marking on the rack’s vertical rail. It is not necessary to mark or place tape on the rack.

Figure 1-2. One Rack Unit

15.9 mm (0.625 inch)

1 U (44 mm [1.75 inches])

15.9 mm (0.625 inch)

12.7 mm (0.5 inch)

CAUTION: If you are installing more than one system, install the mounting rails so that the first system is installed in the lowest available position in the rack.

Rack Installation Guide		9

To mark the rack, perform the following steps:

1Place a mark (or tape) on the rack's front vertical rails where you want to locate the bottom of the system you are installing in the rack. The bottom of each 1-U space is at the middle of the narrowest metal area between holes (marked with a horizontal line on some rack cabinets—see Figure 1-3).

2Place a mark 88 mm (3.5 inches) above the original mark you made (or count up three holes in a rack that meets EIA-310 standards) and mark the rack's front vertical rails with a felt-tipped pen or masking tape (if you counted holes, place a mark just above the top hole). This mark or piece of tape indicates where the system's upper edge will be located on the vertical rails (see Figure 1-3).

Figure 1-3. Marking the Vertical Rails

1 marks on vertical rail (2)

10 Rack Installation Guide

Configuring the Sliding Rail Assemblies

The sliding rail assembly has a rotating mounting bracket at each end of the rail. The position of the bracket determines whether the rail assembly is used as a RapidRail or a VersaRail. The RapidRail side of the bracket has a hook and a latch that secure it to the vertical rail. The VersaRail side of the bracket has three holes and uses screws to attach it to the vertical rail.

NOTE: The rack kit ships with the slide assemblies in the RapidRails configuration.

To change from one type of rail assembly to the other type of rail assembly:

1Lift the blue lever on the rotating mounting bracket (see Figure 1-4).

2Rotate the bracket and slide it up off of the two shoulder standoffs.

3Continue to rotate the bracket 180 degrees until you can set the notches back over the shoulder standoffs.

4Rotate the bracket in the opposite direction until the bracket clicks into place.

Consignes de sécurité

Respectez les consignes de sécurité de ce guide pour assurer votre sécurité personnelle et pour contribuer à protéger votre système et votre environnement de travail de dommages potentiels. Pour obtenir toutes les informations concernant la sécurité et les réglementations, consultez le document Product Information Guide (Guide d'informations sur le produit) fourni avec le système. Les informations sur

la garantie se trouvent soit dans ce document, soit à part.

SÉCURITÉ : montage en rack des systèmes

Pour garantir la stabilité du rack, ainsi que votre sécurité, respectez les précautions suivantes. Reportez-vous également à la documentation accompagnant le système et le rack pour connaître les mises en garde et les procédures spécifiques.

Les systèmes sont considérés comme étant les composants d'un rack. Le terme “composant” fait donc référence à un système mais aussi aux différents périphériques ou matériels associés.

PRÉCAUTION : avant d'installer des systèmes dans un rack autonome, installez d'abord les pieds stabilisateurs avant et latéraux. Pour plusieurs racks associés, installez d'abord les pieds stabilisateurs avant. L'installation de systèmes dans un rack non équipé de pieds stabilisateurs peut provoquer son basculement et entraîner des blessures. Installez toujours les pieds stabilisateurs du rack avant d'ajouter des composants dans celui-ci.

Après avoir installé un système ou des composants dans un rack, ne faites jamais coulisser hors du rack plus d'un composant à la fois. Le poids de plusieurs composants sortis du rack risquerait de le faire basculer et de blesser quelqu'un gravement.

REMARQUE : le système est certifié sur le plan de la sécurité en tant qu'unité autonome et en tant que composant destiné à être utilisé dans un rack Dell, à l'aide du kit de rack client. L'installation du système et du kit d'installation en rack dans une autre armoire n'a reçu aucune homologation des organismes de certification de la sécurité.

Il vous incombe de veiller à ce que la combinaison finale système et rack soit conforme à toutes les normes de sécurité en vigueur, ainsi qu'aux normes électriques locales. Dell décline toute responsabilité et toutes garanties liées à ce type de combinaisons.

•Les kits de rack doivent être installés par des techniciens de maintenance qualifiés. Si vous installez ce kit dans un autre rack, assurez-vous que ce dernier possède les mêmes spécifications qu'un rack Dell.

PRÉCAUTION : ne déplacez pas de rack sans aide. En raison de la hauteur et du poids du rack, cette tâche doit être réalisée par deux personnes au minimum.

•Avant de travailler sur le rack, vérifiez que les pieds stabilisateurs sont fixés au rack, qu'ils touchent le sol et que tout le poids du rack repose sur le sol. Avant d'intervenir sur un rack isolé, installez d'abord les pieds stabilisateurs avant et latéraux. Pour plusieurs racks associés, installez d'abord les pieds stabilisateurs avant.

•Chargez le rack du bas vers le haut, en plaçant toujours l'élément le plus lourd en premier.

•Assurez-vous que le rack est d'aplomb et stable avant de tirer un composant hors de son compartiment.

Consignes générales d'installation

Ce guide d'installation s'adresse à des techniciens de maintenance qualifiés. Il contient les instructions relatives à l'installation d'un ou de plusieurs systèmes dans un rack. La configuration RapidRails™ peut être installée sans outils dans tous les racks du fabricant dotés de trous carrés ; la configuration VersaRails™ peut être installée dans la plupart des racks standard équipés de trous carrés ou ronds. Un kit d'installation est nécessaire pour chaque système.

Avant de commencer

Avant de commencer à installer le système dans le rack, lisez attentivement la section “Consignes de sécurité” à la page 27, ainsi que les consignes de sécurité figurant dans le document Product Information Guide (Guide d'informations sur le produit) pour plus d'informations.

PRÉCAUTION : si vous installez plusieurs systèmes dans un rack, terminez toutes les opérations requises sur le système en cours d'installation avant de passer au suivant.

PRÉCAUTION : les racks peuvent être extrêmement lourds, mais se déplacent assez facilement sur leurs roulettes. Cependant, les roulettes ne possèdent pas de système de freinage. Procédez avec la plus grande prudence pour déplacer un rack. Rentrez ses pieds réglables lorsque vous le changez d'emplacement. Évitez de déplacer le rack le long de rampes ou de plans inclinés trop longs ou trop abrupts, sur lesquels l'armoire pourrait vous échapper. Ressortez les pieds réglables lorsque l'armoire doit être soutenue ou pour lui éviter de glisser sur ses roulettes.

REMARQUE : pour plus d'informations sur l'installation du système proprement dit, voir “Installation du système dans le rack” à la page 37.

Informations importantes concernant la sécurité

Respectez les précautions décrites dans les sous-sections suivantes lors de l'installation du système dans le rack.

PRÉCAUTION : vous devez respecter à la lettre les procédures de ce document afin de garantir votre propre protection ainsi que celle d'autrui. Le système peut être très lourd et volumineux. Une préparation et une planification adéquates sont donc importantes afin d'éviter tout risque de blessure pour vous-même ou autrui. Ces précautions sont d'autant plus importantes lorsque les systèmes sont installés en hauteur.

PRÉCAUTION : n'installez pas de kits prévus pour un autre système. Sinon, vous risquez d'endommager le système et de vous blesser ou de blesser une autre personne.
