As you use your computer, observe the following safe-handling guidelines.
CAUTION: Do not operate your computer with any cover(s) (including computer covers, bezels, filler brackets, front-panel inserts, and so on) removed.
Your computer is equipped with one of the following:
A fixed-voltage power supply — Computers with a fixed-voltage power supply do not have a voltage selection switch on the back panel and operate at only one voltage (see the regulatory label on the outside of the computer for its operating voltage).
An auto-sensing voltage circuit — Computers with an auto-sensing voltage circuit do not have a voltage selection switch on the back panel and automatically detect the correct operating voltage.
A manual voltage selection switch — Computers with a voltage selection switch on the back panel must be manually set to operate at the correct operating voltage.
To help avoid damaging a computer with a manual voltage selection switch, ensure that the voltage selection switch is set to match the AC power available at your location:
115 V/60 Hz in most of North and South America and some Far Eastern countries such as South Korea and Taiwan
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
NOTE: The voltage selection switch must be set to the 115-V position even
though the AC power available in Japan is 100 V.
230 V/50 Hz in some regions in the Caribbean and South America and most of Europe, the Middle East, and the Far East
Also, ensure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.
Before working inside the computer, unplug the computer to help prevent electric shock or system board damage. Certain system board components continue to receive power any time the computer is connected to AC power.
To avoid shorting out your computer when disconnecting a network cable, first unplug the cable from the network adapter on the back of your computer, and then from the network jack. When reconnecting a network cable to your computer, first plug the cable into the network jack, and then into the network adapter.
To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before disconnecting a device from the computer.
To help prevent electric shock, plug the computer and device power cables into properly grounded electrical outlets. These cables are equipped with 3-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 3-wire cable with properly grounded plugs.
To help protect your computer from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
Be sure nothing rests on your computer's cables and that the cables are not located where they can be stepped on or tripped over.
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. Avoid placing loose papers underneath your computer; do not place your computer in a closed-in wall unit or on a bed, sofa, or rug.
Before you open the computer cover, perform the following steps in the sequence indicated.
CAUTION: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not covered by your warranty.
NOTICE: To help avoid possible damage to the system board, wait 5 seconds
after turning off the computer before removing a component from the system
board or disconnecting a device from the computer.
Perform an orderly computer shutdown using the operating system menu.
Turn off your computer and any devices.
Ground yourself by touching 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.
Disconnect your computer and devices, including the monitor, from their
electrical outlets. Also, disconnect any telephone or telecommunication
lines from the computer.
Doing so reduces the potential for personal injury or shock.
Disconnect the power cable to your computer, and then press the power
button to ground the system board.
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, ensure that 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.
CAUTION: 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):
Do not remove components from their antistatic packing material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, discharge static electricity from your body.
When transporting an electrostatic sensitive component, first place it in an antistatic container or packaging.
Handle all electrostatic sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
The following notice may appear throughout this document to remind you of these precautions:
Your computer uses a lithium-ion battery. For instructions about replacing the lithium-ion battery in your computer, refer to the section about replacing the battery in your Dell computer documentation.
Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.
To prevent damage to your computer, the front door is designed to "break away" if it is lifted up too far. If the front door breaks away, you might need to reattach both the front door and the hinge arms.
NOTICE: To disconnect a network cable, first unplug the cable from your
computer and then unplug it from the network wall jack.
Turn off any attached devices and disconnect them from their
electrical outlets.
Disconnect the computer power cable from the wall outlet, and then
press the power button to ground the system board.
If you have installed a padlock through the padlock ring on the back
panel, remove the padlock.

and then lift the lever.
To remove the card, grasp the card by the top corners and lift it out.
If the card is difficult to remove, gently ease the card back and forth to remove it from the connector.
HINT: Installing filler
brackets over empty card-
slot openings is necessary
to maintain Federal
Communications
Commission (FCC)
certification of the
computer. The brackets
also keep dust and dirt out
of your computer.
If you are not replacing the card, install a filler bracket in the empty
card-slot opening.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in "Safety Instructions."
You can increase your computer memory by installing memory modules on the system board. For information on the type of memory supported by your computer, see "Memory" in "Technical Specifications."
NOTICE: If you remove your original memory modules from the computer
during a memory upgrade, keep them separate from any new modules that you
may have, even if the new modules were purchased from Dell. Your original
memory modules must be installed as a pair in either connectors RIMM1 and
RIMM 2 or RIMM 3 and RIMM4. Do not pair one original memory module
with one new memory module in connectors RIMM1 and RIMM2 or RIMM3
and RIMM4. Otherwise, your computer may not start properly.
RDRAM technology requires that all memory connectors be populated with either a memory module or a continuity module. Memory modules and continuity modules are easily identified—memory modules have a metal cover on one side of the module and continuity modules do not.
HINT: The metal cover
on a memory module is
manufactured in various
colors. The color of the
metal cover has no effect
on the module's
performance.
Memory modules are the actual components that provide memory for the microprocessor; continuity modules are used only to complete the memory circuit if memory modules are not installed in all of the memory connectors.
Another RDRAM requirement is that memory modules must be installed in pairs of matched memory size. This means that if you purchased your computer with 128 MB of memory installed and you want to add another 128 MB of memory, you must remove the two continuity modules and replace them with two 64-MB memory modules.
The only two valid memory configurations are:
A pair of matched memory modules installed in connectors RIMM1 and RIMM2 with continuity modules installed in connectors RIMM3 and RIMM4
or
A pair of matched memory modules installed in connectors RIMM1 and RIMM2 and another matched pair installed in connectors RIMM3 and RIMM4
To install memory modules:
HINT: Memory
purchased from Dell is
covered under your
computer warranty.
NOTICE: Be sure to install memory modules in the first two memory
connectors (RIMM1 and RIMM2) nearest the processor before installing
memory modules in the outer two memory connectors (RIMM3 and RIMM4).
NOTICE: All memory connectors must be populated with either a memory
module or a continuity module. The computer will not operate if a memory
connector is unpopulated.
Remove a memory or a continuity module.
Press out the securing clip at each end of the memory module
connector.
Grasp the module and pull up.
If the module is difficult to remove, gently ease the module back and forth to remove it from the connector.
NOTICE: If you remove your original memory modules from the computer
during a memory upgrade, keep them separate from any new modules that you
may have, even if the new modules were purchased from Dell. Your original
memory modules must be installed as a pair in either connectors RIMM1 and
RIMM 2 or RIMM 3 and RIMM4. Do not pair one original memory module
with one new memory module in connectors RIMM1 and RIMM2 or RIMM3
and RIMM4. Otherwise, your computer may not start properly.

This computer supports two types of system boards—a one-piece system board and a two-piece, riser system board. The one-piece system board contains all four PCI slots. The two-piece, riser system board uses a riser extension that contains card slots PCI3 and PCI4. The riser extension attaches to the riser system board at the brown RISER connector on the riser extension. Both types of system boards perform identically and are removed and reinstalled the same way into the computer.
To attach the riser extension to the riser system board:
Align the two metal clips on the riser extension with the two slots on
the metal base of the riser system board.
Align the brown RISER connector on the riser extension with the pad
connectors on the riser system board.
