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 and regulatory information, see the safety instructions
that shipped with your system. Warranty information might be included in
this document or as a separate document.
SAFETY: Rack Mounting of Systems
Observe the following precautions for rack stability and safety. Also refer to
the rack installation documentation accompanying the system and the rack
for specific caution statements and procedures.
Systems are considered to be components in a rack. "Component" refers
to any system as well as to various peripherals or supporting hardware.
CAUTION: Instructions for Rack-Mounted Systems:
• Your rack kit has been approved only for the rack cabinet provided. It is
your responsibility to ensure that installation of the equipment into any
other rack complies with all applicable standards. Dell disclaims all liability
and warranties with respect to combinations of equipment with any other
rack.
• Before installing your equipment in a rack, install all front and side
stabilizers. Failure to install stabilizers can allow the rack to tip over.
• Always load from the bottom up, and load the heaviest items first.
• Do not overload the AC power supply branch circuit that provides power
to the rack.
• Do not stand or step on any components in the rack.
Installation Instructions
This installation guide provides instructions for trained service technicians
installing a 24-unit (U) rack. Information includes assembling the rack
and routing cables through the rack. The 24-U rack can be installed using
the recommended tools.
Installation Guide 5
Rack Requirements
CAUTION: The 24-U rack meets the specifications of American National
Standards Institute (ANSI)/Electronic Industries Association (EIA) standard
ANSI/EIA-310-D-92, Consumer Electronics Association (CEA) Standard CEA-310-E,
International Electrotechnical Commission (IEC) 297, and Deutsche Industrie Norm
(DIN) 41494.
Rack Installation
Before attempting this installation, you should read through this entire
procedure carefully.
Before You Begin
WARNING: Before you begin installing your rack, carefully read "Important
Safety Information," as well as the safety instructions that came with the rack.
WARNING: When installing multiple systems in a rack, complete all of the
procedures for the current system before attempting to install the next system.
WARNING: 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, rough surfaces, or ramps where loss of cabinet control may occur.
Extend the leveling feet for support and to prevent the cabinet from rolling.
WARNING: Avoid rolling the rack cabinet over rough surfaces. Hard impacts to
the casters could cause them to break, and the rack could become unstable and
tip over.
WARNING: Do not attempt to move your rack with components installed. If you
move a fully loaded rack on a slightly uneven floor surface, the rack may become
unstable and tip over.
Important Safety Information
Observe the safety precautions in the following subsections when installing
your system in the rack.
WARNING: 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.
6 Installation Guide
WARNING: For stability, you must ensure that a minimum of 50 lbs. is installed
in the bottom 3-U spaces of the rack cabinet.
Rack Stabilizer Feet
WARNING: 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.
WARNING: 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.

Securing the Rack Leveling Feet
WARNING: Read all statements below before you adjust the leveling feet.
Your rack includes four leveling feet, which are mounted on the corners of
the rack. The leveling feet are designed to align the rack in an upright, level
position when the rack is situated on a slightly uneven floor surface. Before
you install your systems in the rack, deploy and adjust the leveling feet.
When you level your rack, follow these guidelines.
WARNING: When you adjust the leveling feet, ensure that the casters on each
corner of the rack do not rise more than 9.5 mm (3/8 inch) above the floor. If you
exceed 9.5 mm of clearance between the floor and the casters as you adjust the
leveling feet, slowly retract the leveling feet, and then move the rack to another
location that requires minimal adjustments to the leveling feet.
WARNING: Adjust the leveling feet until each leveling foot rests firmly on the
floor. Proper contact with the floor ensures that each leveling foot is supporting
the weight of the rack and prevents the rack from swaying in any direction. If
the leveling feet are not all in firm contact with the floor, the rack can become
unstable and tip over.
WARNING: Do not attempt to move your rack with the leveling feet deployed.
Always retract the leveling feet before moving the rack. Having the leveling feet
deployed when you move the rack may cause the rack to tip over.
WARNING: Always level the rack and install the stabilizing feet before you
install your systems. A fully loaded rack may tip over if your rack is resting on
an uneven floor surface and the leveling and stabilizing feet are not supporting
the weight of the rack.
NOTE: If the rack is not leveled properly, you might not be able to install the
stabilizer feet, which are necessary to prevent the rack from tipping over.
18 Installation Guide
1
Using a screwdriver, lower the leveling foot until it rests on the floor.
2
If you need to lower the foot further, tighten the hex nut clockwise
with a 12-mm wrench (see Figure 1-10).

22 Installation Guide
Routing Cables
The 24-U rack offers several features that simplify cable routing
(see Figure 1-14).
• Four power distribution unit (PDU) channels in each rack flange allow you
to route power cables to the systems mounted in the rack.
• Cable clips can be mounted in the PDU channels to keep cables out
of the way and help prevent cords from becoming tangled.
You can route cables out of the rack in two ways on a standard configuration:
• Through the cable exit at the bottom of the back doors (see Figure 1-14)
• Through the adjustable cable slot at the top of the rack and into a cable
raceway (see Figure 1-14).
