Safety First—For You and Your
Computer
The procedures in this section require that you open the cover and work
inside your computer.
NOTICE: Do not attempt to service the co mputer yourself, except as
explained in this guide and elsewhere in Dell documentation. Always follow
installation and service instructions closely.
NOTICE: Before disconnectin g a device from the computer or removing a
component from the system board, verify that the standby power light on the
system board has turned off. For the location of this light, see the syste m
board.
Working inside your computer is saf e—if you observe the following
precautions.
CAUTION: FOR YOUR PERSONAL SAFETY AND PROTECTION OF
THE EQUIPMENT.
Before you start to work on the computer , perform the following steps in the
sequence indicated:
1 Turn off the computer and all devices.
2 Touch an unpainted metal surface on the computer chassis , such as the
metal around the card-slot openings at the back of your computer,
before touching anything inside your computer.
3 Disconnect the computer and devices from their electrical outlets.
Doing so reduces the potential for personal injury or shock. Also
disconnect any telephone or telecommunication lines from the
computer.
In addition, take note of these safety gu idelines 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, pre ss 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.
11
• 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 b y its edges,
not by its pins.
CAUTION: There is a danger of a new battery exploding if it is
incorrectly installed. Replace the batter y only with the same or
equivalent type recomme nded by the manufacture r. Discard used
batteries according to the manufacturer's instructions.
Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To
www.dell.com | support.dell.com
prevent static damage, discharge static electricity from your body before you
touch any of your computer’s electroni c 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 f r om electrostatic
discharge (ESD):
• When unpacking a static-sensitive component from its shipping
carton, do not remove the compon ent from the antistati c packing
material until you are ready to install the component in your
computer. Just before unwrapping the antistatic packaging, be sure to
discharge static electric ity from your bo dy.
12
• 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.
Ergonomic Computing Habits
CAUTION: Improper or prolonged keyboard u se may resul t in
injury.
CAUTION: Viewing the monitor screen for extended periods of
time may result in eye strain.
For comfort and efficiency, observe the following ergonomic guidelines
when setting up and using your computer:
• Position your computer 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 comforta ble viewing distance (u sually 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.

Connecting Devices
When you connect external devices to your computer's back panel, follow
these guidelines:
• Check the documentation that accompanied the device for specific
installation and configuration instructions.
For example, you must connect most devices to a particular
input/output (I/O) connector to operate properly. Also, external
devices like a mouse or printer usually require you to load device
drivers into computer memory before they will work.
• Always attach external devices while your computer is turned off. Then
turn on the computer before turning on any external devices, unless
the documentation for the device specifies otherwise. (If the computer
does not seem to recognize the device, try turning on the device before
turning on the computer.)
About Your Computer 29
NOTICE: When you disconnect external devices from the back of the
computer, wait 10 to 20 seconds after turning off the computer before you
disconnect any devices to avoid possible damage to the system board.
Parallel Connector
This is used to connect printers. Default designation is LPT1.
NOTE: The integrated
parallel connector is
automatically di sabled if
the computer detects an
installed expansion card
www.dell.com | support.dell.com
containing a parallel
connector configured to
the same address as
specified in “Additional
System Setup Options.”
NOTE: USB mice will
only wake the computer
from the S1 (standby) and
S3 (suspend to RAM)
states with a click.
Mouse Connector
Turn off the computer and any attached devices before connecting a mouse
to the computer. If your computer uses Microsoft Windows
Windows NT 4.0, Dell installed the necessary mouse drivers on your hard
drive.
2000 or
USB Connectors
These are used to attach USB-compliant devices such as keyboards, mice,
printers, and computer speakers to your computer.
Integrated Network Adapter Connector
The network adapter, which includes a Remote Wake Up feature, has the
following lights:
• A yell ow network activity light flashes when the computer is
transmitting or receiving network data. (A high volume of network
traffic may make this light appear to be in a steady “on” state.)
• A dual-colored link integrity light, which is green when a good
connection exists between a 10-megabit per second (Mbps) network
and the computer , or is orange when a good connection exists between
a 100-Mbps network and the computer. W h en the light is off, the
computer is not detecting a physical connection to the network.
30 About Your Computer
Network Cable Requirements
The network adapter connector attaches an unshielded twisted pair (UTP)
Ethernet cable to your computer. Pr ess one end of the UTP cable to an RJ45
jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending
on your network configuration, and press the other end of the UTP cable
into the network adapter connec tor until the cable snaps securely into place
Dell recommends the use of Category 5 wiring and connectors for our
customers’ networks.
Line-In Jack
This jack is used to attach record/playback devices such as cassette players,
CD players, and VCRs. Connect the line-out cable from any of these
devices to the line-in jack.
Line-Out Jack
This jack is used to attach computer speakers. This jack is amplified, so
speakers with integrated amplifiers are not required. Connect the audio
cable from the speakers to this jack.
Microphone Jack
This jack is used to attach a standard personal computer microphone.
Connect the audio cable from the microphone to the microphone jack.
Serial Connectors
Default port designations: COM1 for port 1 and COM2 for port 2. You can
reassign the serial connector’s designation if you add an expansion card
containing a serial connector using this designation.
If you set the computer’s serial connectors to Auto in system setup and add
an expansion card containing a serial connector configured to a specific
designation, the compute r automatically maps (assigns ) the integrated
ports to the appropriate COM setting as necessary.
Before you add a card with a serial connector, check the documentation that
accompanied your software to make sure that the software can be mapped
to the new COM port designation.
Keyboard Connector
Attach the keyboard cable to the 6-pin connector on the back panel.
