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: 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 injure someone.
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.
• 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 components
in a rack.

1-6 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
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 Dell system. Using the rack kit for another system may result in damage to the system and personal
injury.
NOTE: If your system is a tower version, you must install a tower-to-rack conversion kit. Instructions
for installing this kit are included in a separate document.
The RapidRails rack kit can be installed in most industry-standard rack cabinets.
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.
Before You Begin
Before you begin installing your system in the rack, carefully read the safety instructions found
at the beginning of this guide, as well as the safety instructions found in your system’s
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. 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.

Rack Installation Guide 1-7
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
NOTE: Your rack may already be marked and not require this procedure.
You must allow 5 U (8.75 inches) of vertical space for each system you install in the rack
(see Figure 1-3).
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:
1 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).
2 Place a mark approximately 8.75 inches above the original mark you made (or count up
15 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).
1 U (44 mm or 1.75 inches)
12.7 mm (0.5 inch)
15.9 mm (0.625 inch)

Installing the RapidRails Slide Assemblies
1 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.
2 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).
3 At the back of the cabinet, pull back on the mounting-bracket flange until the mounting
hooks are in the appropriate hole, and then push down on the flange until the mounting
hooks seat in the square holes and the push button pops out and clicks.
