Safety Instructions: Dell™ PowerEdge™
24U Rack Installation Guide
Safety Precautions • Rack Stabilizer • When
Using the Rack • Protecting
Against Electrostatic Discharge
This rack is intended to be installed by certified service
technicians. Throughout this document, there are blocks of text printed in bold type.
These blocks of text are warnings that indicate the potential for bodily harm or personal
injury if not heeded. When you see these warning messages in the text, carefully follow
the instructions in the warning to prevent injury. An example of the warning format
follows:
 |
WARNING: A WARNING indicates the potential for
bodily harm and tells you how to avoid the problem. |
|
WARNING: Installing components in the rack
without the front stabilizer installed could allow the rack to tip over and cause bodily
injury under certain circumstances. Always install the stabilizer before installing
components in the rack. |
Before installing the equipment in the rack, you must install the
stabilizer. The stabilizer helps prevent the rack from tipping over when a computer or
storage system is installed and then pulled out of the rack to the fully extended position
of the slide assemblies. Refer to Setting Up the
Rack, for instructions on installing the stabilizer.
|
WARNING: After installing
components in a rack, never pull more than one component out of the rack on its slides at
one time. The weight of more than one component extended on slides could cause the rack to
tip over and injure someone. |
As you use the rack, observe the following safety guidelines:
- To help prevent electric shock, plug the rack power cables into
properly grounded power sources. These cables are equipped with plugs to ensure proper
grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you
must use an extension cable, use a three-wire cable with properly grounded plugs.
- To help protect the equipment in the rack from sudden, transient
increases and decreases in electrical power, use a surge suppressor, line conditioner, or
uninterrupted power supply (UPS).
- Be sure that nothing rests on the rack's power cables and that the
cables are not located where they can be stepped on or tripped over.
|
WARNING: To prevent personal
injury, after installing any component of the rack, extend the slides to allow the locking
pin to engage the holes locking the slides into their fully extended position. This
assures alignment of the locking pins into the holes and reliability of the locking
mechanism. Slowly engage the slides until you hear a click when the slides have locked in
place. WARNING: Due to the weight of the
components, never allow your feet or other body parts to be directly under the rack
component during installation or removal of the component. |
Static electricity can harm delicate electronic components. To
prevent static damage, discharge static electricity from your body before you touch any
electronic components, such as an expansion card. You can do so by touching an unpainted
metal surface on a computer chassis.
As you continue to work, periodically touch an unpainted metal
surface to remove any static charge your body may have accumulated.
In addition to the preceding precautions, you can also take the
following steps to prevent damage from ESD:
- When unpacking a static-sensitive component from its shipping carton,
do not remove the component's antistatic packing material until you are ready to install
the component in your computer. Just before unwrapping the antistatic packaging, be sure
to discharge static electricity from your body.
- When transporting a sensitive component, first place it in an
antistatic container or packaging.
- Handle all sensitive components in a static-safe area. If possible,
use antistatic floor pads and workbench pads.
The following caution may appear throughout this document to remind
you of these precautions:
