Rack Installation Guide 1-1
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 complete safety,
regulatory, and warranty information, refer to your Dell™ system’s System Information
document.
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 warning
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.
CAUTION: Installing system components in a rack without the front and side
stabilizers installed could cause the rack to tip over, potentially resulting in
bodily injury or death under certain circumstances. Therefore, always install the
stabilizers 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 injure
someone.
NOTE: Your Dell system is safety-certified as a free-standing unit and as a component for use in
a Dell rack cabinet using the Dell customer rack kit. The installation of your system and rack kit
in any non-Dell 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 non-Dell rack cabinet
evaluated for suitability by a certified safety agency. Dell disclaims all liability and warranties in
connection with such combinations.
• System rack kits are intended to be installed in a Dell 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.
• Do not move large racks by yourself. Due to the height and weight of the rack, it is
recommended that a minimum of two people perform this task.
• Before working on the rack, make sure that the stabilizers are secured 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.

1-2 Rack Installation Guide
www.dell.com | support.dell.com
• 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 acomponent
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.
Installation Instructions
This installation guide provides instructions for trained service technicians installing one or
more systems in a rack cabinet. The RapidRails™ rack kit can be installed in all Dell™ rack
cabinets, 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.
CAUTION: Do not attempt to 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.
NOTE: If your system is a tower version, you must first convert the system to a rack version
using a tower-to-rack conversion kit. Instructions for installing this kit are included in this
document.
RapidRails Rack Kit Contents
The RapidRails rack kit consists of one pair of RapidRails mounting rails (see Figure 1-1).

Rack Installation Guide 1-3
Figure 1-1. RapidRails Rack Kit Contents
Dell Rack Requirements
NOTICE: This rack kit is intended to be installed in a Dell rack by trained service technicians.
If you install the kit in any other rack, be sure that the rack 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.
VersaRails Rack Kit Contents
The VersaRails rack kit includes the following items (see Figure 1-2):
• One pair of VersaRails mounting rails
• Eight 10-32 x 0.5-inch Phillips screws

Non-Dell Rack Requirements
NOTICE: This 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.
Before You Begin
Before you install your system in the rack, read the “Safety Instructions” in the front of this
document, as well as the safety instructions in your System Information booklet 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.
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 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 and anchored to the floor could cause the rack to tip over, potentially
resulting in bodily injury or death under certain circumstances. Therefore,
always install and anchor the stabilizer feet before installing components in the
rack.
CAUTION: After installing systems in a rack, never pull more than one system
out of the rack 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. See the documentation provided with the rack cabinet
for instructions on installing and anchoring the stabilizer feet.

Rack Installation Guide 1-5
Recommended Tools and Supplies
The following items make the installation easier:
• A #2 Phillips screwdriver (if installing a VersaRails kit)
• Torx T-10 driver (if installing the tower-to-rack kit)
• 3/16-inch hex-head wrench (if installing the tower-to-rack kit)
Installation Tasks
Installing a rack kit involves the following tasks:
1Removing the rack doors
2Marking the rack
3Installing the mounting rails in the rack
4Installing the tower-to-rack conversion kit (if needed)
5Installing the system in the rack
6Replacing the rack doors
NOTE: The procedures that follow apply to both Dell rack cabinets and rack cabinets not
manufactured by Dell unless identified as specific to one or the other.
Removing the Rack Doors
See the procedures for removing doors in the documentation provided with your Dell 24-U
and 42-U rack cabinets. If you have a Dell PowerEdge™ 4210 rack cabinet, see the
procedures in the Dell PowerEdge 4210 Rack Installation Guide. If you have a rack cabinet
not manufactured by Dell, see the manufacturer’s documentation for removing doors.
CAUTION: Because of the size and weight of the rack cabinet doors, never
attempt to remove or install them by yourself.
Marking the Rack
NOTE: If you are installing a VersaRails rack kit, skip to the procedure, “Installing the
VersaRails Mounting Rails.”
You must allow 3-U (5.25 inches) of vertical space for each system you install in the rack.
Dell rack cabinets and rackcabinets not manufactured by Dell that meet EIA-310standards
have an alternating pattern of three holes per U with center-to-center hole spacing
(beginning at the top hole of a1-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).
