Safety Precautions | Rack Stabilizer Feet | 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 a warning 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 and side stabilizer feet
installed could allow the rack to tip over and cause
bodily injury under certain circumstances. Always install
the stabilizer feet before installing components in the
rack. |
Before installing the equipment in the rack, you must install
the stabilizer feet. The stabilizer feet help 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 feet.
|
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
uninterruptible power supply.
- Be sure 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 green
push-button locks to engage the holes locking the slides
into their fully extended position. This assures
alignment of the push buttons into the holes and
reliability of the locking mechanism. 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.
