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 information,

see the

Product Information

Guide

.

SAFETY: 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 injure someone.

NOTE: Your system is safety-certified as a free-standing unit and as a component for use in a rack

cabinet using the customer rack kit when both the rack cabinet and rack kit were designed for your

system. 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 have the final combination of system and rack kit in a

cabinet evaluated for suitability by a certified safety agency. The manufacturer disclaims all warranties

and liability in connection with such combinations.

•

System rack kits are intended to be installed in an approved rack by trained service

technicians. If you install the kit in any other rack, be sure that the rack meets the

specifications.

• 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.

• 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 power 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 system/component when servicing other components

in a rack.

1-6 Rack Installation Guide

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

without tools in manufacturer’s rack cabinets that have square holes; the VersaRails™ rack kit can

be installed in most industry-standard rack cabinets that have square or round holes. The

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

required for each system installed in the rack.

CAUTION: Do not install rack kit components designed for another system. Use only the rack kit for

your Dell system. Using the rack kit for another system may result in damage to the system and personal

injury.

NOTE: If your system is a tower version, you must install a tower-to-rack conversion kit. Instructions

for installing this kit are included in a separate document.

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

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.

Before You Begin

Before you begin installing your system in the rack, carefully read the safety instructions found

at the beginning of this guide, as well as the safety instructions found in your system’s

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 the casters. The cabinet has no

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.

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.

Rack Stabilizer Feet

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

the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore,

always install the stabilizer feet before installing components in the rack.

Rack Installation Guide 1-7

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.

The stabilizer feet help prevent the rack from tipping over when a system or other component 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.

Marking the Rack

NOTE: Your rack may already be marked and not require this procedure.

You must allow 5 U (8.75 inches) of vertical space for each system you install in the rack

(see Figure 1-3).

Figure 1-3. One Rack Unit

CAUTION: If you are installing more than one system, install the slide assemblies so that the first

system is installed in the lowest available position in the rack.

To mark the rack, perform the following steps:

1

Place a mark on the rack’s front vertical rails where you want to locate the bottom of

the system you are installing in the rack cabinet.

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 1-4).

2

Place a mark approximately 8.75 inches above the original mark you made (or count up

15 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 1-4).
