Rack Installation Guide 1-1

CAUTION: Safety Instructions

Use the following safety guidelines to help ensure your own personal safety and to help

protect your system and working environment from potential damage. For complete safety

information, see the System Information Guide.

Rack Mounting of Systems

Observe the following precautions for rack stability and safety.

Systems are considered to be components in a rack. Thus, "component" refers to any

system as well as to various peripherals or supporting hardware.

CAUTION: Installing systems in a rack without the front and side stabilizers

installed could cause the rack to tip over, potentially resulting in bodily injury

under certain circumstances. Therefore, always install the stabilizers 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.

1-2 Rack Installation Guide

www.dell.com | support.dell.com

Installation Instructions

This installation guide provides instructions for trained service technicians installing one or

more systems in an open-frame relay rack or in a rack cabinet. The RapidRails™ rack kit can

be installed in all the system manufacturer's rack cabinets without tools, and the

VersaRails™ rack kit can be installed in most industry-standard rack cabinets. The

procedures for installing both RapidRails and VersaRails rack kits are similar. One rack kit is

required for each system to be installed in the rack cabinet.

This guide includes procedures for the following rack kits:

• RapidRails kit in a four-post rack cabinet

• VersaRails kit in a four-post rack cabinet

• Two-post kit (installed in either center-mount or flush-mount configuration)

Before You Begin

Before you begin installing your system in the rack, carefully read "CAUTION: Safety

Instructions," found earlier in this guide, as well as the safety instructions found in your

System 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.

• 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.

• After a component is inserted into the rack, carefully extend the rail into a locking

position, and then slide the component into the rack.

• 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.

CAUTION: Safety Instructions (continued)

Rack Installation Guide 1-3

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."

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 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.

Four-Post Rack Installation

Before attempting this installation, you should read through this entire procedure carefully.

Rack Stabilizer Feet

CAUTION: Installing systems in a rack without the front and side stabilizer feet

installed and anchored to the floor could cause the rack to tip over, potentially

resulting in bodily injury under certain circumstances. Therefore, always install

and anchor the stabilizer feet before installing components in the rack.

CAUTION: After installing systems in a rack, never pull more than one system

out of the rack on its slide assemblies at one time. The weight of more than one

extended system could cause the rack to tip over and cause injury.

JO525bk0.book Page 3 Monday, January 27, 2003 12:29 PM

1-4 Rack Installation Guide

www.dell.com | support.dell.com

The stabilizer feet help prevent the rack from tipping over when a system is pulled out of

the rack with the slide assemblies fully extended. 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 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

RapidRails Rack Kit Contents

The RapidRails rack kit includes the following items (see Figure 1-1):

• One pair of RapidRails slide assemblies

• One cable-management arm

• One cable tray

• Two stop blocks

• Releasable tie wraps (not shown in Figure 1-1)
