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 system’s System Information document.
Notes, Notices, Cautions, and Warnings
Throughout this guide, blocks of text may be accompanied by an icon and printed in
bold type or in italic type. These blocks are notes, notices, cautions, and warnings,
and they are used as follows:
NOTE: A NOTE indicates important information that helps you make better use of
your computer system.
NOTICE: A NOTICE indicates either potential damage to hardware or loss
of data and tells you how to avoid the problem.
CAUTION: A CAUTION indicates a potentially hazardous situation which, if
not avoided, may result in minor or moderate injury.
WARNING: A WARNING indicates a potentially hazardous situation which,
if not avoided, could result in death or serious bodily injury.
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.

WARNING: Installing Dell system components in a Dell 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: 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
suitability by a certified safety agency.
•System rack kits are intended to be installed in a Dell rack by trained service tech-
nicians. 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

Installation
This procedure provides instructions for installing a Dell PowerApp appliance in a twopost open-frame relay rack, such as those found in telecommunications equipment
facilities. Both 3-inch and 6-inch wide two-post racks are accommodated.
The two-post open-frame relay rack must be properly secured to the floor, to the
ceiling or upper wall, and where applicable, to adjacent racks, using floor and wall
fasteners and bracing specified or approved by the rack manufacturer or by industry
standards. Refer to the two-post open-frame relay rack manufacturer’s installation
documentation for precautionary warnings and information before attempting this
installation.
CAUTION: Do not attempt to install the PowerApp appliance into a twopost open-frame relay rack that has not been securely anchored in place.
Damage to the appliance and personal injury may result.
Refer to “Safety Instructions” at the front of this document for additional safety
information regarding rack installation.

Marking the Rack
1.Determine where you want to place the bottom of the PowerApp appliance.
CAUTION: If you are installing more than one PowerApp appliance, install
the first appliance in the lowest available position in the rack.
2.Mark the upper and lower-mounting positions on the two posts.
Each 1-U (1.75-inch) vertical space has three holes, with center-to-center spacing
between holes (beginning at the center of the top hole of a 1-U space) of 0.625,
