Safety Instructions

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

protect your server, storage system, or appliance from potential damage. For com-

plete safety, regulatory, and warranty information, refer to your system’s System

Information document.

Notes, Notices, Cautions, and Warnings

Throughout this guide, blocks of text may be accompanied by an icon and printed in

bold type or in italic type. These blocks are notes, notices, cautions, and warnings,

and they are used as follows:

NOTE: A NOTE indicates important information that helps you make better use of

your computer system.

NOTICE: A NOTICE indicates either potential damage to hardware or loss

of data and tells you how to avoid the problem.

CAUTION: A CAUTION indicates a potentially hazardous situation which, if

not avoided, may result in minor or moderate injury.

WARNING: A WARNING indicates a potentially hazardous situation which,

if not avoided, could result in death or serious bodily injury.

Precautions for Rack-Mountable Products

Observe the following precautions for rack stability and safety. Also refer to the rack

installation documentation accompanying the system and the rack for specific warn-

ing and/or caution statements and procedures.

Servers, storage systems, and appliances are considered to be components in a rack.

Thus, “component” refers to any server, storage system, or appliance, as well as to

various peripherals or supporting hardware.

WARNING: Installing Dell system components in a Dell rack without the

front and side stabilizers installed could cause the rack to tip over, poten-

tially resulting in bodily injury under certain circumstances. Therefore,

always install the stabilizers before installing components in the rack.

2D786bk0.book Page v Thursday, January 18, 2001 8:44 PM

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: Dell’s servers, storage systems, and appliances are certified as components

for use in Dell’s rack cabinet using the Dell customer rack kit. The final installation of

Dell systems and rack kits in any other brand of rack cabinet has not been approved by

any safety agencies. It is the customer’s responsibility to have the final combination of

Dell systems and rack kits for use in other brands of rack cabinets evaluated for suit-

ability by a certified safety agency.

•System rack kits are intended to be installed in a Dell rack by trained service tech-

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

specifications of a Dell rack.

•Do not move large racks by yourself. Due to the height and weight of the rack,

Dell recommends a minimum of two people to accomplish this task.

•Before working on the rack, make sure that the stabilizers are secure to the rack,

extend 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 com-

ponent 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 system/component when servicing other

systems/components in a rack.

Appliances and PowerEdge™ 350

Systems — Rack Installation

Guide

This installation guide provides instructions for trained service technicians installing

one or more Dell PowerApp 100 or 110 or PowerEdge 350 systems in a rack. This

guide includes procedures for the following three rack kits:

•Two-post center-mount

•Two-post flush-mount

•Four-post rack cabinet

One rack kit is required for each system to be installed in the rack.

Two-Post Center-Mount Rack Kit

Installation

This procedure provides instructions for installing a Dell system in a two-post open-

frame relay rack, such as those found in telecommunications equipment facilities.

Both 3-inch and 6-inch wide two-post racks are accommodated.

The two-post open-frame relay rack must be properly secured to the floor, to the

ceiling or upper wall, and where applicable, to adjacent racks, using floor and wall

fasteners and bracing specified or approved by the rack manufacturer or by industry

standards. See the two-post open-frame relay rack manufacturer’s installation docu-

mentation for precautionary warnings and information before attempting this

installation.

CAUTION: Do not attempt to install the system into a two-post open-frame

relay rack that has not been securely anchored in place. Damage to the

system and personal injury may result.

See “Safety Instructions”at the front of this document for additional safety informa-

tion regarding rack installation.

Marking the Rack

1. Determine where you want to place the bottom of the system.

CAUTION: If you are installing more than one system, install the first sys-

tem in the lowest available position in the rack.

2. Mark the upper and lower-mounting positions on the two posts.

Each 1-U (1.75-inch) vertical space has three holes, with center-to-center spacing

between holes (beginning at the center of the top hole of a 1-U space) of 0.625,

0.625, and 0.5 inch (see Figure 1-2).

1-4 Rack Installation Guide

Attaching the Brackets

1. Locate one of the two brackets and align it over the two threaded holes on the

side of the system (see Figure 1-3).

2. Secure the bracket to the system chassis using two 10-24 x 0.375-inch screws

(see Figure 1-3).

Repeat this step to install the remaining bracket on the other side of the system.

Figure 1-3. Securing the System in the Rack

Installing the System in the Rack

CAUTION: Due to the size and weight of the system, never attempt to install

the system by yourself.

1. Lift the system into position between the two posts, with the hole in the mount-

ing bracket aligned one hole above the mark you made in the two posts.

2. Secure the system to the rack using a 12-24 x 0.5-inch screw through the mount-

ing bracket to the front of the left and right posts (see Figure 1-3).

3. Attach the front bezel, if it is not already attached, to the system (see the

Installation and Troubleshooting Guide for instructions).

This completes the two-post center-mount rack installation.
