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
www.dell.com | support.dell.com
Installation Instructions
This installation guide provides instructions for trained service technicians installing one or
more systems in a rack cabinet or in an open-frame relay rack. The RapidRails™ rack kit can
be installed in all the system manufacturer’s rack cabinets without tools, and the
VersaRails™ rack kit can be installed in most 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 ease in troubleshooting and the identification of system health, some rack kits include a
status-indicator cable assembly that extends the information from 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 the 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 "Safety Instructions" 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 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.
NOTE: For instructions on installing the system itself, see "Installing the System in the Rack."
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.
Recommended Tools and Supplies
You may need the following tools and supplies to install the system in a four-post rack:
• #2 Phillips screwdriver
• Masking tape or a felt-tip pen, for use in marking the mounting holes to be used

1-6 Rack Installation Guide
www.dell.com | support.dell.com
Marking the Rack
You must allow 1 U (44 mm, or 1.75 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 rear 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."
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 1-3).
