Safety First—For You and Your Computer

Use the following safety guidelines to help protect your computer system
from potential damage and to ensure your own personal safety.

When Working Inside Your Computer

Before you open the computer cover, perform the following steps in the
sequence indicated.

NOTICE: Do not attempt to service the computer yourself, except as

www.dell.com | support.dell.com

explained in your online Dell documentation or otherwise provided to you.

Always follow installation and service instructions closely.

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 instructio ns.

Turn off the computer and any peripherals.

1
2 Wear a wrist grounding strap, and clip it to an unpainted metal

surface, such as the padlock loop on the back of the chassis. If a wrist

grounding strap is not available, ground yourself by touching an

unpainted metal surface on the chassis, such as the power supply,

before touching anything inside your computer.

10 Safety Information

While you work, periodically touch an unpainted metal surface on the

computer chassis to dissipate any static electricity that might harm

internal components. Also avoid touching components or contacts on

a card and avoid touching pins on a chip.

3 Disconnect your computer and peripherals from their power sources.

Before disconnecting a peripheral device from the computer , wait 10 to

20 seconds after disconnecting the computer from its electrical outlet.

Before removing a component from the system board, verify that the

standby power light on the system board has turned off. To locate this

light, see "System Board Components" or the interior service label.

Disconnect any telephone or telecommunication lines from the

computer. Doing so reduces the potential for personal injury or shock.

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.

• Handle components and cards with care. Do not 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.

Also see "Protecting Against Electrostatic Discharge." Dell recommends
that you periodically review the safety instructions in your System
Information Guide.

Safety Informa tion 11

Protecting Against Electrostatic Discharge

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 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

www.dell.com | support.dell.com

accumulated.
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 compon ent from the antistat ic packing
material until you are ready to install the component in your
computer. Just before unwrapping the antistatic packaging, be sure to
discharge static electri city 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.

12 Safety Information

Ergonomic Computing Habits

CAUTION: Improper or prolonged keyboard use may result i n

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 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 comforta ble viewing distance (usually 510 to

610 mm [20 to 24 inches] from your eyes).

• Ensure that 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, ensure that 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.

Network Adapter

The network adapter has the following lights:

• A yellow 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 network link and speed light, which is green when a

good connection exists between a 10-Mbps network and the computer,
or is orange when a good connection exists between a 100-Mbps
network and the computer. When the light is off, the computer is not
detecting a physical connection to the network.

The network controller includes a Remote Wake Up feature. For more
information, see "Network Operations" and "Power Management."

NOTICE: Do not connect a modem cable to the network adapter. Voltage

from telephone communications can damage the network adapter.

Network Connection Requirements

Press one end of the UTP Ethernet cable into the network adapter on your
computer until the cable snaps securely into place. Connect the other end
to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or hub,
depending on your network configuration.

Dell recommends the use of Category 5 wiring and connectors for our
customers' networks.

NOTE: Verify the type of network device to which you are connecting the

computer. A hub typically operates at 10-Mbps. A switch can operate at 10- or
100-Mbps. Ensure th at the network adapter is configured for the appropriate
speed. See network adapter diagnostics and configuration utility on Dell

Diagnostics.

Installing and Configuring Software

See "Finding Information and Assistance" for a list of software resources
available to you from Dell, including drivers, utilities, documentation, and
operating system backups. Before installing software that was not provided
with your Dell computer, check the software for viruses with virus-scanning
software. Viruses can quickly use all availab le system me mory, damage o r
destroy data stored on the hard drive, and permanently affect the
performance of the programs they infect. Several commercial virus­scanning programs are available for purchase, and many websites distribute
virus-scanning programs that you can download.

www.dell.com | support.dell.com

Before you install a program, read its documentation to learn how the
program works, what hardware it requires, and what its defaults are. A
program usually includes installation instructions in its accompanying
documentation and a software installation routine on its program
diskette(s) or CD(s).

The software installation routine assists you in transferring the appropriate
program files to your computer's hard drive. Installation instructions may
provide details about how to configure your operating system to successfully
run the program. Always read the installation instructions before running a
program's installation routine.

When you run the installation routine, be prepared to respond to prompts
for information about how your computer's operating system is configured,
what type of computer you have, and what peripherals are connected to
your computer.

NOTE: If you experience any problems while installing or operating your

software, see "Software Problems."

TAPI

The TAPI features of your computer enable Microsoft® Windows®-based
applications to operate with a wide variety of telephony devices, including
voice, data, fax, video, and so forth. TAPI applications require a T API service
provider (TSP), which is a software driver that allows TAPI applications to
communicate with different types of TAPI hardware.

Microsoft Windows provide a TSP called Uni modem, which is a "universal"

modem service provider that supports a wide range of commonly used

modems. For more information on Unimodem, see your Windows
documentation. When using a TAPI device other than a modem, such as a

PBX or a voice processing card, you will need a TSP provided by the

manufacturer of the device.
The TAPI system-board connector uses a 4-pin cable to interface your

internal TAPI-compliant expansion card with the audio system in your
computer. To locate the TAPI system-board connector, see "System Board

Components" or the interior service label. Your computer supports TAPI-

compliant cards using the standard TAPI connector. For example, you can
connect your modem to the TAPI connector and then use your audio
speakers and microphone as a speakerphone. The microphone carries your
voice into the computer and then through the TAPI system board connector
to your modem card. The caller’s voice enters through the modem card to
the T API system board connector and then out to the speakers. You can also
use this configuration to record and play sound files over the phone.

IEEE 1394 (FireWire)

FireWire is a high-speed data bus that is defined by IEEE Standard 1394-

1995. This protocol is a scalable, flexible, low-cost digital interface. It can
move large amounts of data between computers and peripheral devices,
using simplified cabling, hot-swapping, and transfer speeds up to 4 00Mbps.

Because of the very high data rates that FireWire can handle, it is ideal for
use with multimedia devices such as digital video cameras and high-speed
hard drives and printers. FireWire speeds the transfer of multimedia data
and large files, enabling a PC to connect directly to digital consumer

Power Management

Your computer can be set to use less power when you are not working. You
control the power usage through the OS installed on your computer and
certain option setti n g s in system setup. These periods of reduced power are
called "sleep states":

• Standby. In this sleep state, power is reduced or turned off for most

components, including the cooling fans. However, system memory
remains active .

• Hibernate. This sleep state reduces power consumption to a minimum

by writing all data in system memory to a hard drive and then
removing system power. Waking up from this state restarts the
computer, and the memory contents are restored. Operation then
resumes where the computer left off when it entered the hibernation
state.

This state is not supported by Windows NT 4.0.

NOTE: All components installed in the computer must support this

feature and have the appropriate drivers loaded to enter hibernation. For
more information, see th e manufacturer’s documentation for each

System Board Installation

When installing memory modules in the system board sock ets and not using
the optional memory riser boards, observe the following guidelines:

• Each memory socket on the system boar d must be occupied either by a

RIMM or a CRIMM.

72 Removing and Installing Parts

• Memory sockets must be upgraded in matched pairs. In other words,

two sockets in a pair must contain modules of identical capacity,
number of components, and speed. See "System Board Memory

Components" to identify pairs of sockets.

• Mixed pairs of ECC and non-ECC modules all function as non-ECC.

• Be sure to install a RIMM in socket 1 first (closest to the processor)

before installing modules in the other sockets.

• The system board supports PC600 and PC800 memory modules.

Riser Board Installation

When installing memory modules using the optional memory riser boards,
observe the following guidelines:

• The memory riser boards must be installed in system board memory

sockets 1 and 2. Memory riser board A must be installed in system
board memory socket 1, and riser board B must be installed in system
board socket 2. System board memory sockets 3 and 4 can either be
empty or contain CRIMMs. Sockets 3 and 4 cannot contain RIMMs
with memory riser boards installed in sockets 1 and 2. See "System

Board Memory Components" to identify the system board sockets.

• Memory sockets on the riser boards must be upgraded in matched

pairs. In other words, two sockets in a pair must contain modules of
identical capacity, number of components, and speed. See "Memory

Riser Board Components" to identify pairs of sockets.

• Not all memory sockets on the memory riser boards need to be

populated: if one or more pairs of memory sockets contain RIMMs,
then the next pair must contain CRIMMs, and the remaining pair(s)
can be empty. For example, if the first and second pairs of memory
sockets on the riser boards contain RIMMs, then the third pair must
contain CRIMMs, and the fourth pair can remain empty.

• Mixed pairs of ECC and non-ECC modules all function as non-ECC.

• The optional memory riser boards only support PC800 memory

modules.

Removing and Installing Parts 73

Addressing Memory with 4-GB Configurations

If you use optional memory riser boards and eight, 512-MB RIMMs, you can
install 4 GB of physical computer memory. Current workstation-class OSs
(such as Microsoft

®

Windows NT® and Windows® 2000) can only utiliz e a
maximum of 4 GB of address space. However, the amount of memory
available to the OS will be slightly less than 4 GB.

Certain components within the computer require address space in the 4-GB
range. Any address space reserved for these components cannot be used by
computer memory. The following is a list of some components that require
memory address space:

www.dell.com | support.dell.com

• System ROM

•APIC(s)

• Integrated PCI devices, such as the network adapter, SCSI controller,

and IEEE 1394 controller

• PCI and AGP expansion cards

• The AGP Aperture size spe cified in system setup

At system start-up, the BIOS i dentifies the components that require address
space. Starting at the highest end of the 4-GB range, it assigns those
addresses working downward. All remaining addresses are then available for
use by installed computer memory.

In other words, the BIOS dynamically calculates the amount of reserved
address space required. It then subtracts the reserved address space from
4 GB to determine the amount of usable address space:

• If the total installed computer memory is less than the usable address

space, all installed computer memory is available for use by the OS.

• If the total installed computer memory is equal to or greater than the

usable address space, a small portion of installed computer memory is
not available for use by the OS.
