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 com-
plete safety, regulatory, and warranty information, refer to your system’s System
Information booklet.

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 warn-
ing 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.
WARNING: Installing Dell system components in a Dell rack without the
front and side stabilizers installed could cause the rack to tip over, poten-
tially resulting in bodily injury under certain circumstances. Therefore,
always install the stabilizers before installing components in the rack.

iv
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: Dell’s servers, storage systems, and appliances are certified as components
for use in Dell’s rack cabinet using the Dell customer rack kit. The final installation of
Dell systems and rack kits in any other brand of rack cabinet has not been approved by
any safety agencies. It is the customer’s responsibility to have the final combination of
Dell systems and rack kits for use in other brands of rack cabinets evaluated for suit-
ability by a certified safety agency.
•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,
Dell recommends a minimum of two people to accomplish this task.
•Before working on the rack, make sure that the stabilizers are secure 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.
•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 com-
ponent 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.

Installing the Slide Assemblies in the Rack
NOTE: If the slide assemblies were preinstalled by Dell, you can skip this section.
You must allow 2 U (3.5 inches) of vertical space for each system you install in the
rack.
NOTE: The vertical rails of the rack are marked by small indentations in 1-U
increments (see Figure 1-6).
Figure 1-6. One Rack Unit
For more information about requirements for installing components in a Dell rack, see
the Dell Rack Advisor software available on the Dell Web site at
http://support.dell.com.
CAUTION: If you are installing more than one system, install the slide
assemblies so that the first system is installed in the lowest available posi-
tion in the rack.
To install the slide assemblies in the rack, perform the following steps:
1. Place the front of the template on the vertical rails at the front of the rack where
you want to install the system.
Ensure that the printing on the template identifies the side facing outward as the
template front.
1 U (1.75 inches)

support.dell.com Rack Installation Guide 1-9
2. Mark the rack’s front vertical rails with a felt-tipped marker or place self-adhesive
masking tape where the system’s upper and lower edges will be located (see
Figure 1-7).
3. Make a mark or place tape on the vertical rails next to the template’s V-shaped
notches.
Figure 1-7. Using Template to Mark Vertical Rails
4. At the front of the rack cabinet, position one of the slide assemblies so that its
mounting bracket flange fits between the marks or tape you placed on the rack,
marking the upper and lower edges of the template (see Figure 1-8).
The hooks on the mounting bracket should align with the marks you made from
the V-shaped notches in the template.
5. Align the slide-assembly mounting-bracket flange (on the front of the slide
assembly) with the square holes in the front vertical rail (see Figure 1-8).
6. Push forward until the mounting tabs are secure in the square holes on the
vertical rail and the push-button clicks and pops out.
7. Push back on the back slide assembly mounting bracket flange until the mounting
tabs lock into the square holes on the back vertical rail.
