Rack Installation Guide 1-5
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
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. 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. The manufacturer 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.
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.
• 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.

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.
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 determining the health of your system, some rack kits include a
status-indicator cable that relays 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 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.
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.
• 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 1-7
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 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.
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

1-10 Rack Installation Guide
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."
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).
1 U (44 mm or 1.75 inches)
12.7 mm (0.5 inch)
15.9 mm (0.625 inch)
15.9 mm (0.625 inch)
12.7 mm (0.5 inch)

Rack Installation Guide 1-11
2 Place 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).
