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: Before installing systems in a rack, install the front and side

stabilizers on stand-alone (single) 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.

CAUTION: 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 cause injury.

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.

Dell™ Rack Installation Guide 5

• 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 systems/components in a rack.

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

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

NOTICE: The RapidRails 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 Dell™ Rack Installation Guide

Before You Begin

Before you begin installing your system in the rack, carefully read “Safety Instructions”, found earlier in this guide, 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 the casters.

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: Before installing systems in a rack, install the front and side

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

You must allow 4 U (7 inches) of vertical space for each system you install in the rack (see Figure 1-3).

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

Figure 1-3. One Rack Unit

12.7 mm (0.5 inch)

15.9 mm (0.625 inch)

1 U (44 mm or 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 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:

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).

Dell™ Rack Installation Guide 11

Place a mark approximately 7 inches above the original mark you made (or count up 12 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).

12 Dell™ Rack Installation Guide

Installing the RapidRails Slide Assemblies

At the front of the rack cabinet, position one of the RapidRails slide assemblies so that its mounting-bracket flange fits in the appropriate location on the rack (see Figure 1-5).

The top mounting hook on the rail assembly’s front-mounting bracket flange should enter the top hole between the marks on the vertical rails.

Push the slide assembly forward until the top mounting hook enters the square hole just below the upper marks or tape you placed on the vertical rail. Next, push down on the mounting-bracket flange until the mounting hooks seat in the square holes and the push button pops out and clicks (see Figure 1-5).

At the back of the cabinet, pull back on the mounting-bracket flange until the mounting hooks are in the appropriate holes, and then push down on the flange until the mounting hooks seat in the square holes and the push button pops out and clicks.

Repeat steps 1 through 3 for the slide assembly on the other side of the rack.

NOTE: Ensure that the rails are mounted at the same vertical position

on both sides of the rack.

Installing the VersaRails Slide Assemblies

At the front of the rack cabinet, place a VersaRails slide assembly so that its mounting-bracket flange fits between the marks or tape (or numbered location) on the rack (see Figure 1-6).

The holes on the front of the mounting bracket should align with the holes between the marks on the front vertical rail.

Install a 10-32 x 0.5-inch flange-head Phillips screws in the mounting flange’s top hole and the bottom hole (see Figure 1-6).

At the back of the cabinet, pull back on the mounting-bracket flange until the mounting holes align with their respective holes on the back vertical rail.

Install 10-32 x 0.5-inch flange-head Phillips screws in the second and third holes (middle holes) of the back mounting flange to secure the slide assembly to the back vertical rail.

NOTE: The top and bottom flange holes will be used later for installing the

cable-management arm retainer.

Repeat steps 1 through 4 for the slide assembly on the other side of the rack.

NOTE: Ensure that the rails are mounted at the same vertical position on both

sides of the rack.

Installing the Cable Tray and Cable-Management Arm

This procedure is performed in two phases. First, install the cable tray to the back of the system chassis. Next, install the cable-management arm on the cable tray.

Attaching the Cable Tray to the System

NOTE: Depending on the cable tray that ships with your rail kit, you will need

to follow the procedure for mounting the tray on the back of the system chassis. Both cable trays are illustrated in Figure 1-8.

Mounting Type I

Align the formed metal tabs along the bottom of the cable tray with the mating slots at the back of the system chassis.

Insert the tabs into the slots and rotate the tray downward to the secure position (see Figure 1-8).

Secure the tray to the system with the two captive thumbscrews.

Mounting Type II

Align the formed metal tabs along the sides of the cable tray with the bent metal notches on the inner walls at the back of the system chassis.

Slide the tabs over the metal notches and press the tray downward to the secure position (see Figure 1-8).

Secure the tray to the system with the two captive thumbscrews.

CAUTION: The cable tray cannot support the weight of the system. Do not grasp

the cable tray when lifting the system. Lift the system only by the chassis edges.

Securing the Cable-Management Arm

NOTE: The cable-management arm can be installed on either side of the cable tray.

Facing the back of the rack cabinet, push the tab on the front end of the cable-management arm into the latch on the cable tray until the latch clicks (see Figure 1-8).
