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.

• 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.

1-U Keyboard Tray Installation

NOTE: One unit, or U, equals 1.75 vertical inches.

This guide provides instructions for installing and using the Dell PowerEdge™ 1-U keyboard tray in

a four-post rack cabinet. The pullout tray assembly accommodates a keyboard with a trackball.

An attached cable-management arm routes the keyboard/trackball cables to the back of the rack.

Important Safety Information

Observe the following safety precautions when installing components 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: Rack cabinets can be extremely heavy and move easily on their casters. They have 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.

CAUTION: Installing components 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.

Recommended Tools and Supplies

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

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

Keyboard Tray Kit Contents

The keyboard tray kit includes the following items. See Figure 1-1.

• One 1-U keyboard tray with cable-management arm installed

NOTE: A keyboard is not shipped preinstalled in the tray. You must order a separate Dell rack-mount

keyboard to complete the installation.

• 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)

Installation Guide 1-7

• One pair of RapidRails

• 10-32 x 0.5-inch flange-head Phillips screws and centering washers (four sets)

(not shown in Figure 1-1)

Figure 1-1. 1-U Keyboard Tray Kit Contents

Installing the 1-U Keyboard Tray

Installing the 1-U keyboard tray consists of performing the following tasks in order:

Removing the rack doors

Marking the rack

Installing the slide assemblies (RapidRails) in the rack

Installing the keyboard tray in the rack

Attaching the cable-management arm to the rack

Installing the keyboard in the tray

Completing the cable connections

Replacing the rack doors

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 two doors where they will not injure someone if the doors accidently fall over.

1-8 Installation Guide

Marking the Rack

You must allow 1 U (44 mm, or 1.75 inches) of vertical space for installing the keyboard tray. 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 rear vertical rails. See Figure 1-2.

Rack cabinets have square holes.

NOTE: The vertical rails are sometimes engraved with 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. If you choose this method, skip ahead to the procedure "Installing the

RapidRails Slide Assemblies."

NOTE: Installing the 1-U keyboard tray in the top U space of the Dell PowerEdge 2410 rack is not

recommended.

To mark the rack, perform the following steps:

Use a felt-tipped marker or masking tape to mark the rack’s front vertical rails where you want

to locate the bottom of the 1-U keyboard tray.

The bottom of each 1-U space is at the middle of the narrowest metal area between the holes

(marked with a horizontal line on some rack cabinets). See Figure 1-2.
