Safety Instructions: Dell™ PowerEdge™
2300 Systems Installation and Troubleshooting Guide
Use the
following safety guidelines to help protect your computer system from potential damage and
to ensure your own personal safety.
As you use your computer system, observe the following safety
guidelines:
- Be sure your computer, monitor and attached
peripherals are electrically rated to operate with the AC power available in your
location.
- To help avoid possible damage to the system
board, wait 5 seconds after turning off the system before removing a component from the
system board or disconnecting a peripheral device from the computer.
- To help prevent electric shock, plug the
computer and peripheral power cables into properly grounded power sources. These cables
are equipped with three-prong plugs to help 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 your computer system from
sudden, transient increases and decreases in electrical power, use a surge suppressor,
line conditioner, or un-interruptible power supply (UPS).
- Be sure nothing rests on your computer
system's cables and that the cables are not located where they can be stepped on or
tripped over.
- Do not spill food or liquids on your
computer. If the computer gets wet, consult Checking Inside the Computer.
- Do not push any objects into the openings of
your computer. Doing so can cause fire or electric shock by shorting out interior
components.
- Keep your computer away from radiators and
heat sources. Also, do not block cooling vents.
 WARNING: Improper or prolonged keyboard
use may result in injury.
For comfort and efficiency, observe the following ergonomic
guidelines when setting up and using your computer system:
- Position your system so that the monitor and
keyboard are directly in front of you as you work. Special shelves are available (from
Dell and other sources) to help you correctly position your keyboard.
- Set the monitor at a comfortable viewing
distance (usually 510 to 610 millimeters [20 to 24 inches] from your eyes).
- Make sure the monitor screen is at eye level
or slightly lower when you are sitting in front of the monitor.
- Adjust the tilt of the monitor, its contrast
and brightness settings, and the lighting around you (such as overhead lights, desk lamps,
and the curtains or blinds on nearby windows) to minimize reflections and glare on the
monitor screen.
- Use a chair that provides good lower back
support.
- Keep your forearms horizontal with your
wrists in a neutral, comfortable position while using the keyboard or mouse.
- Always leave space to rest your hands while
using the keyboard or mouse.
- Let your upper arms hang naturally at your
sides.
- Sit erect, with your feet resting on the
floor and your thighs level.
- When sitting, make sure the weight of your
legs is on your feet and not on the front of your chair seat. Adjust your chair's height
or use a footrest, if necessary, to maintain proper posture.
- Vary your work activities. Try to organize
your work so that you do not have to type for extended periods of time. When you stop
typing, try to do things that use both hands.
Before you
remove the computer covers, perform the following steps in the sequence indicated.

CAUTIONS: Do not
attempt to service the computer system yourself, except as explained in this guide and
elsewhere in Dell documentation. Always follow installation and service instructions
closely. To help avoid possible
damage to the system board, wait 5 seconds after turning off the system before removing a
component from the system board or disconnecting a peripheral device from the computer. |
1. Turn
off your computer and any peripherals.
2.
Disconnect your computer and peripherals from their power sources. Also, disconnect any
telephone or telecommunication lines from thecomputer.
Doing so reduces
the potential for personal injury or shock.
3. Touch an
unpainted metal surface on the chassis, such as the metal around the card-slot openings at
the back of the computer, before touching anything inside your computer.
While you work,
periodically touch an unpainted metal surface on the computer chassis to dissipate any
static electricity that might harm internal components.
In addition,
take note of these safety guidelines when appropriate:
- When you disconnect a cable, pull on its
connector or on its strain-relief loop, not on the cable itself. Some cables have a
connector with locking tabs; if you are disconnecting this type of cable, press in on the
locking tabs before disconnecting the cable. As you pull connectors apart, keep them
evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make
sure both connectors are correctly oriented and aligned.
- Handle components and cards with care. Don't
touch the components or contacts on a card. Hold a card by its edges or by its metal
mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its
pins.
WARNING: There is a danger of a new battery exploding
if it is incorrectly installed. Replace the battery only with the same or equivalent type
recommended by the manufacturer. Discard used batteries according to the manufacturer's
instructions.
Static
electricity can harm delicate components inside your computer. To prevent static damage,
discharge static electricity from your body before you touch any of your computer's
electronic components, such as the microprocessor. You can do so by touching an unpainted
metal surface on the computer chassis.
As you
continue to work inside the computer, periodically touch an unpainted metal surface to
remove any static charge your body may have accumulated.
You can also
take the following steps to prevent damage from electrostatic discharge (ESD):
- When unpacking a static-sensitive component
from its shipping carton, do not remove the component from the 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.
