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.
• Make sure that the rack is level and stable before extending a component from the
rack.

1-2 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 in all the manufacturer’s rack cabinets without tools, and the VersaRails™ rack
kit can be installed in many 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, for 3- or
6-inch-wide racks)
For ease in troubleshooting and the identification of system health, these rack kits include a
status-indicator cable that extends the information on the two-color status indicators on
the front and back panels to the back of the cable-management arm. For more information
on these indicators, see your system User’s Guide.
Before attempting this installation, you should read through this entire document carefully.
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.
• 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
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.
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’s System Information document 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.

1-4 Rack Installation Guide
www.dell.com | support.dell.com
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. Refer to 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 tools and supplies to install the system in a four-post rack:
• A #2 Phillips screwdriver (for installing VersaRails slide assemblies)
• Masking tape or a felt-tip pen, for use in marking the mounting holes to be used

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.
Marking the Rack
You must allow 2 U (88 mm, or 3.5 inches) of vertical space for each system you install in
the rack. 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 back vertical rails (see Figure 1-3). Rack cabinets may have round or square holes.
NOTE: The vertical rails may be marked by horizontal lines and numbers in 1-U
increments. If you wish, 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."

Rack Installation Guide 1-7
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:
1Place 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).
2Place a mark 88 mm (3.5 inches) above the original mark you made (or count up six
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).
