Additional Safety Precautions
To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions.
General Precautions
Observe the following general precautions for using and working with your system:
Observe and follow service markings. Do not service any Dell product except as explained in your Dell system documentation. Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to electrical shock. Components inside these compartments should be serviced only by a Dell authorized service technician.
If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or contact your Dell authorized service provider:
The system cable, extension cable, or plug is damaged.
An object has fallen into the product.
The product has been exposed to water.
The product has been dropped or damaged.
The product does not operate correctly when you follow the operating instructions.
Keep your system components away from radiators and heat sources. Also, do not block cooling vents.
Do not spill food or liquids on your system components, and never operate the product in a wet environment. If the computer gets wet, see the appropriate chapter in your troubleshooting guide or contact a Dell-authorized service provider.
Do not push any objects into the openings of your system components. Doing so can cause fire or electric shock by shorting out interior components.
Use the product only with Dell products or other Dell-approved equipment.
Allow the product to cool before removing covers or touching internal components.
Use the correct external power source. Operate the product only from the type of power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult your Dell service provider or local power company.
To help avoid damaging your system components, be sure the voltage selection switch (if provided) on the power supply is set to match the power available at your location:
115 volts (V)/60 hertz (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
230 V/50 Hz in most of Europe, the Middle East, and the Far East
Also be sure that your monitor and attached devices are electrically rated to operate with the power available in your location.
Use only approved power cable(s). If you have not been provided with a power cable for your server, storage system, or appliance, or for any AC-powered option intended for your system, purchase a power cable that is approved for use in your country. The power cable must be rated for the product and for the voltage and current marked on the products electrical ratings label. The voltage and current rating of the cable should be greater than the ratings marked on the product.
To help prevent electric shock, plug the system/components and peripheral power cables into properly grounded electrical outlets. 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.
Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products plugged into the extension cable or power strip does not exceed 80 percent of the extension cable or power strip ampere ratings limit.
To help protect your system/components from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
Position system cables and power cables carefully; route system cables and the power cable and plug so that they cannot be stepped on or tripped over. Be sure that nothing rests on your system components cables or power cable.
Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local/national wiring rules.
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.
Handle batteries carefully. Do not disassemble, crush, puncture, short external contacts, dispose of in fire or water, or expose batteries to temperatures higher than 60 degrees Celsius (140 degrees Fahrenheit). Do not attempt to open or service batteries; replace batteries only with batteries designated for the product.
Turn down the volume before using headphones or other audio devices.
Precautions for Servers, Storage Systems, and Appliances
Follow the additional safety guidelines for your system:
Unless your installation and/or troubleshooting documentation specifically allows it, do not remove enclosure covers, attempt to override the safety interlocks, or access any components inside the system. Depending on your system, installation and repairs may be done only by individuals who are qualified to service your computer or storage system equipment and trained to deal with products capable of producing hazardous energy levels.
When connecting or disconnecting power to hot-pluggable power supplies, if offered with your Dell product, observe the following guidelines:
Install the power supply before connecting the power cable to the power supply.
Unplug the power cable before removing the power supply.
If the system has multiple sources of power, disconnect power from the system by unplugging all power cables from the power supplies.
Move products with care; ensure that all casters and/or stabilizers are firmly connected to the computer or storage system. Avoid sudden stops and uneven surfaces.
Precautions for Rack-Mountable Products
Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation accompanying the system and the rack for specific warning and/or caution statements and procedures.
Servers, storage systems, and appliances are considered to be components in a rack. Thus, "component" refers to any server, storage system, or appliance, as well as to various peripherals or supporting hardware.
WARNING: Installing Dell system components in a Dell rack without the front and side stabilizers installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers before installing components in the rack.
After installing system/components in a rack, never pull more than one component out of the rack on its slide assemblies at one time. The weight of more than one extended component could cause the rack to tip over and injure someone.
NOTE: Dells servers, storage systems, and appliances are certified as components for use in Dells rack cabinet using the Dell customer rack kit. The final installation of Dell systems and rack kits in any other brand of rack cabinet has not been approved by any safety agencies. It is the customers responsibility to have the final combination of Dell systems and rack kits for use in other brands of rack cabinets evaluated for suitability by a certified safety agency.
System rack kits are intended to be installed in a Dell rack by trained service technicians. If you install
the kit in any other rack, be sure that the rack meets the specifications of a Dell rack.
Do not move large racks by yourself. Due to the height and weight of the rack, Dell recommends a minimum of two people to accomplish this task.
Before working on the rack, make sure that the stabilizers are secure to the rack, extend to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack.
Always load the rack from the bottom up, and load the heaviest item in the rack first.
Make sure that the rack is level and stable before extending a component from the rack.
Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the slide rails can pinch your fingers.
After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into the rack.
Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating.
Ensure that proper airflow is provided to components in the rack.
Do not step on or stand on any system/component when servicing other systems/components in a rack.
Precautions for Products With Modems, Telecommunications, or Local Area Network Options
Observe the following guidelines when working with options:
Do not connect or use a modem or telephone during a lightning storm. There may be a risk of electrical shock from lightning.
Never connect or use a modem or telephone in a wet environment.
Do not plug a modem or telephone cable into the network interface controller (NIC) receptacle.
Disconnect the modem cable before opening a product enclosure, touching or installing internal components, or touching an uninsulated modem cable or jack.
Do not use a telephone line to report a gas leak while you are in the vicinity of the leak.
Precautions for Products With Laser Devices
Observe the following precautions for laser devices:
Do not open any panels, operate controls, make adjustments, or perform procedures on a laser device other than those specified in the products documentation.
Only authorized service technicians should repair laser devices.
When Working Inside Your Computer
Before you remove the computer covers, perform the following steps in the sequence indicated.
CAUTION: Some Dell systems can be serviced only by trained service technicians because of high voltages and energy hazards. 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.
NOTICE: 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 devices.
2. 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.
3. Disconnect your computer and devices from their power sources. Also, 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 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 that both connectors are correctly oriented and aligned.
Handle components and cards with care. Dont 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 manufacturers instructions.
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 computers 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.
The following notice may appear throughout this document to remind you of these precautions:
NOTICE: See "Protecting Against Electrostatic Discharge."
Ergonomic Computing Habits
CAUTION: Improper or prolonged keyboard use may result 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 you set up and use 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 that the monitor screen is at eye level or slightly lower when you sit 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 you use the keyboard or mouse.
Always leave space to rest your hands while you use 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 chairs 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.
1 Monitor screen at or below eye level

Memory Module Installation Guidelines
Starting with the socket nearest to the system board's center, the DIMM sockets are labeled "DIMM3" through "DIMM0" (see Figure 15). When you install memory modules, follow these guidelines:
Install a DIMM in socket DIMM3 (the socket toward the center of the board) before socket DIMM2, socket DIMM2 before socket DIMM1, and so on.
The reason for installing memory in the back-most socket first is for ease of future installations.
If you install different sizes of memory modules, install them in order of descending capacity, beginning with the highest-capacity DIMM in socket DIMM3.
You do not need to install memory modules in pairs.

Microprocessor
The microprocessor and heat-sink assembly is secured to the system board in a zero-insertion-force (ZIF) socket.
To remove the microprocessor and heat sink assembly, perform the following steps.
CAUTION: See "Safety Instructions" before working inside your system.
CAUTION: The microprocessor and heat-sink assembly can get extremely hot during system operation. Be sure the assembly has had sufficient time to cool before you touch it.
CAUTION: When handling the microprocessor and heat-sink assembly, take care to avoid sharp edges on the heat-sink.
NOTICE: See "Protecting Against Electrostatic Discharge." 1. Turn off the system, including any attached peripherals, and disconnect the AC power cable from
its power source.
2. Remove the front bezel.
3. Remove the cover.
4. Disconnect the AC power cable and all peripheral cables from the back panel of the system.
5. Release the clip securing the heat sink to the microprocessor socket by first inserting a small flat- tip screwdriver into the upper slot at the front of the socket to release the clamp, and then releasing the clip from the opposite side of the socket.
6. Grasp the end of the ZIF socket arm and bend it out slightly until it disengages from the socket tab.
7. Swing the ZIF arm up to the upright position.
The microprocessor and heat-sink assembly are now unlocked from the ZIF socket.
NOTICE: The microprocessor may adhere to the heat-sink assembly because of a layer of thermal grease applied to the top of the microprocessor. When lifting the heat sink away, use care to prevent the microprocessor from separating from the heat sink and falling on system board components.
8. Lift the microprocessor and heat-sink assembly away from the ZIF socket (see Figure 19).

Be careful not to touch the surfaces coated with thermal grease. The beveled surface on the heat-sink covers the part of the ZIF socket that is not covered by the microprocessor.
6. Drop the heat-sink clip into the heat sink's center groove, with the end of the clip that has two slots facing the front of the ZIF socket.
7. Gently hold the heat-sink in place as you press down on the end of the shorter end of the heat- sink clip (the end that has a single slot) until that end snaps into its tab on the back of the ZIF socket.
8. Use your thumb to press down on the front end of the heat-sink clip (the end that has two slots) until it snaps into the socket tab.
9. Replace the cover, install the power cord, and turn on the system's power switch.
Battery
The system battery maintains configuration, date, and time information in a special section of memory when you turn of the system. The operating life of the battery ranges from 2 to 5 years, depending on how you use the system (for example, if you keep the system on most of the time, the battery gets little use and thus lasts longer). You may need to replace the battery if an incorrect time or date is displayed during the boot routine along with the following or similar message:
Time-of-day not set -- please run SETUP program
Strike the F1 key to continue, F2 to run the setup utility
or
System CMOS checksum bad -- Run SETUP
Strike the F1 key to continue, F2 to run the setup utility
or
Invalid configuration information -- please run SETUP program
Strike the F1 key to continue, F2 to run the setup utility
To determine if the battery needs replacing, reenter the time and date through the System Setup program. Turn off the system for a few hours, and then turn it on again. Enter the System Setup program. If the date and time are not correct in the System Setup program, replace the battery.
NOTES: Some software may cause the system time to speed up or slow down. If the system seems to operate normally except for the time kept in the System Setup program, the problem may be caused by software rather than by a defective battery.
If the system is turned off for long periods of time (for weeks or months), the NVRAM may lose its system configuration information. This situation is not caused by a defective battery.
You can operate the system without a battery; however, the system configuration information maintained by the battery in NVRAM is erased each time you shut down the system. Therefore, you must reenter the system configuration information and reset the options each time the system boots until you replace the battery.
The battery is a 3.0-volt (V), coin-cell CR2032-type battery. To remove the battery, perform the following steps.
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 manufacturers instructions.
1. Enter the System Setup program and, if possible, make a printed copy of the System Setup screens.
See "Using the System Setup Program" for instructions.
2. Shut down the system, including any attached peripherals, and disconnect the system from the electrical outlet.
NOTICE: See "Protecting Against Electrostatic Discharge."
3. Remove the cover.
4. Pry the battery out of its socket with your fingers or with a blunt, nonconductive object such as a
plastic screwdriver.
5. Install the new battery with the side labeled "+" facing up (see Figure 21).
Figure 21. Battery Replacement
6. Replace the cover, and then reconnect the system and peripherals to their AC power sources and turn them on.
7. Enter the System Setup program to confirm that the battery is operating properly.
8. Enter the correct time and date through the System Setup program's Time and Date settings. Also reenter any system configuration information that is no longer displayed on the System Setup screens, and then exit the System Setup program.
9. To test the newly installed battery, turn off and disconnect the system from the electrical outlet for at least an hour.
10. After an hour, plug in and turn on the system and enter the System Setup program. If the time and date are still incorrect, see "Getting Help" in your system Installation and Troubleshooting Guide for instructions on obtaining technical assistance.

System Board Jumpers
Overview
This section provides specific information about the jumpers on the system board. It also provides some basic information on jumpers and switches and describes the connectors and sockets on the various boards in the system.
JumpersA General Explanation
Jumpers provide a convenient and reversible way of reconfiguring the circuitry on a printed circuit board. When installing replacement parts or reconfiguring the system, you may need to change jumper settings on the system board. You may also need to change jumper and/or switch settings on expansion cards or drives.
To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated.
NOTICE: Make sure the system is turned off before you change a jumper setting. Otherwise, damage to the system or unpredictable results may occur.
A jumper is referred to as open or unjumpered when the plug is pushed down over only one pin or if there is no plug at all. When the plug is pushed down over two pins, the jumper is referred to as jumpered. The jumper setting is often shown in text as two numbers, such as 1-2. The number 1 is printed on the circuit board so that you can identify each pin number based on the location of pin 1.
System Board Jumpers
Figure 1 shows the location of the configuration jumpers on the system board. Table 1 lists the function of these jumpers.

Using the System Password Feature
NOTICE: The password features provide a basic level of security for the data on your system. However, they are not foolproof. If your data requires more security, it is your responsibility to obtain and use additional forms of protection, such as data encryption programs.
Your Dell system is shipped to you without the system password feature enabled. If system security is a concern, you should operate your system only with system password protection. Two types of passwords can be establisheda supervisor password and a user password.
NOTICE: If you leave your system running and unattended without having a system password assigned, or if you leave your system unlocked so that someone can disable the password by changing a jumper setting, anyone can access the data stored on your hard-disk drive.
Using the Supervisor Password Feature
Your Dell system is shipped with the supervisor password feature disabled, which allows you to enter the System Setup program and assign a password. When the Supervisor Password Is option is enabled, the system prompts you for the supervisor password whenever you enter the System Setup program. If system security is a concern, you should operate your system with supervisor password protection.
You can assign a supervisor password whenever you use the System Setup program. After a supervisor password is assigned, only those who know the password have full use of the System Setup program. To delete or change an existing supervisor password, you must know the supervisor password (see "Disabling or Changing an Existing Supervisor Password" ).
If you assign and then forget a supervisor password, a trained service technician must open the system and change a jumper setting to disable the supervisor password feature (see "Disabling a Forgotten Password"). Note that the user password is erased at the same time.
Assigning a Supervisor Password (System Setup Only)
Before you can assign a supervisor password, you must enter the System Setup program and select the Set Supervisor Password option.
NOTE: The supervisor password controls the user password access to the system setup.
When a supervisor password is assigned, the setting shown for the Set Supervisor Password option is Installed.
When no supervisor password is assigned and the password jumper on the system board is in the uninstalled position (its default), the setting shown for the Set Supervisor Password option is Not Installed. Only when this option is set to Not Installed can you assign a supervisor password, using the following procedure:
1. Enter the System Setup program by pressing
2. Select the Security screen.
3. Verify that the Supervisor Password Is option is set to Not Installed.
4. Select the Set Supervisor Password option and press
The system prompts you to Enter Supervisor Password.
5. Type your supervisor password.
You can use up to seven characters in your password.
As you press each character key (or the spacebar key for a blank space), an asterisk (*) placeholder appears in the field.
The password assignment operation recognizes keys by their location on the keyboard; it is case sensitive. This means that the software distinguishes between lowercase and uppercase characters. For example, if you have an M in your password, the system does not recognize either M or m as correct; your system will only accept M. Certain keys and key combinations are not valid. If you enter one of these keys or combinations, the system does not accept them. To erase a character when entering your password, press
NOTE: To escape from the field without assigning a supervisor password, press the
6. Press
The system prompts you to Confirm New Password, followed by another empty seven-character field in square brackets.
To confirm your new password, type it a second time and press
The system tells you the Password Successfully Installed.
The password setting changes to Installed. Your supervisor password is now set; you can exit the System Setup program and begin using your system. Note, however, that password protection does not take effect until you reboot the system by turning the system off and then on again.
Using Your Supervisor Password to Secure Your System Setup
If the Supervisor Password Is option is set to Installed, the following prompt appears:
Enter CURRENT Password
After you type the correct supervisor password and press
If a wrong or incomplete supervisor password is entered, the following message appears:
Enter CURRENT Password
If an incorrect or incomplete supervisor password is entered again, the same message appears.
The third and subsequent times an incorrect or incomplete supervisor password is entered, the system displays the following message:
Invalid Password-System Halted
To reboot the system and either set a new password, press or the reset button on the system unit.
The number of unsuccessful attempts made to enter the correct supervisor password can alert you to an unauthorized person attempting to use your system.
Even after your system is turned off and on, the previous message is displayed each time an incorrect or incomplete supervisor password is entered.
NOTE: The supervisor password only applies to the System Setup program. A user password should be installed to completely secure your system. See "Assigning a Supervisor Password (System Setup Only)."
Deleting or Changing an Existing Supervisor Password
To delete or change an existing supervisor password, perform these steps:
1. Enter the System Setup program by pressing
2. Select the Security screen field to verify that the Supervisor Password Is option is set to Installed.
3. Select the Set Supervisor Password option and press
The system prompts you to Enter Current Password.
4. Type your current supervisor password and press
The system prompts you to Enter Supervisor Password.
NOTE: If you want to delete the password and not enter a new password, press
5. To assign a new password follow the procedure from step 4 in "Assigning a Supervisor Password (System Setup Only)."
Using the User Password Feature
Your system is shipped to you with the user password feature disabled. After you assign a user password, the system prompts you for the user password during the boot process. If system security is a concern, you should operate your system with user password protection.
You can assign a user password, as described in "Assigning a User Password," whenever you use the System Setup program. After you assign a user password, only those who know the password have full use of the system.
If you assign and then forget a user password, you must remove the system cover and change a jumper setting to temporarily disable the user password feature (see "Disabling a Forgotten Password"). Note that the supervisor password is erased at the same time.
NOTICE: If you leave your system running and unattended without having a system password assigned, or if you leave your system unlocked so that someone can disable the password by changing a jumper setting, anyone can access the data stored on your hard-disk drive.
Assigning a User Password
Before you can assign a user password, you must enter the System Setup program and select the Set User Password option.
To assign a user password, perform the following steps:
1. Enter the System Setup program by pressing
2. Select the Security screen.
3. Select the Set User Password option and press
The system prompts you to Enter User Password.
4. Type your user password.
You can use up to seven characters in your password.
As you press each character key (or the spacebar key for a blank space), an asterisk (*) placeholder appears in the field.
The password assignment operation recognizes keys by their location on the keyboard; it is case sensitive. This means that the software distinguishes between lowercase and uppercase characters. For example, if you have an M in your password, the system does not recognize either M or m as correct; your system will only accept M. Certain keys and key combinations are not valid. If you enter one of these keys or combinations, the system does not accept them. To erase a character when entering your password, press

The system tells you that the Password Successfully Installed.
The password setting changes to Installed. Your supervisor password is now set; you can exit the System Setup program and begin using your system. A change to the Set User Password option becomes effective immediately (rebooting the system is not required).
NOTES: The user password can be the same as the supervisor password.
If the two passwords are different, the user password can be used as an alternate supervisor
password. However, the supervisor password cannot be used in place of the user password.
Operating With a User Password Installed
If Set User Password is set to Installed, you must enter the correct user password before you can modify the majority of the System Setup options. When you start the System Setup program, the program prompts you to type the password.
If you do not enter the correct password in three tries, the system displays the following message:
Invalid Password-System Halted
Deleting or Changing an Existing User Password
To delete or change an existing user password, perform the following steps:
1. Enter the System Setup program by pressing
2. Select the Security screen field to verify that the User Password Is option is set to Installed.
3. Select the Set User Password option and press
The system prompts you to Enter Current Password.
4. Type your current user password and press
The system prompts you to Enter User Password.
NOTE: If you want to delete the password and not enter a new password, press
5. To assign a new password, follow the procedure from step 4 in "Assigning a User Password (System Setup Only)."
Disabling a Forgotten Password
If the administrator or user forgets the supervisor or user password, you cannot operate the system or change settings in the System Setup program until a trained service technician opens the system chassis, changes the password jumper setting to disable the passwords, and erases the existing passwords.
To disable a forgotten supervisor password or user password, perform the following steps.
NOTICE: See "Protecting Against Electrostatic Discharge."
1. Shut down and power off your system and disconnect the system and peripherals from their electrical outlets.
2. Remove the system cover.
