Each computer system uses a high-performance Peripheral Component Interconnect (PCI) design that allows you to configure the computer system to your initial requirements and then add Dell-supported upgrades as necessary. System Features Your system offers the following features: q An Intel Pentium II or Pentium III microprocessor. The Intel Pentium II and Pentium III microprocessors include MMXTM technology designed to handle complex multimedia and communications software. This microprocessor incorporates new instructions and data types as well as a technique called single instruction, multiple data (SIMD) that allows the microprocessor to process multiple data elements in parallel, thereby improving overall system performance. q A keyboard command (<\>) that lets you switch between the microprocessor's rated speed and a slower compatibility speed. file:///C|/temp/dell/docs/9030t/intro.htm (1 of 11)12/1/2008 12:54:34 PM Introduction: Dell OptiPlex GX1 Small-Form-Factor System User's Guide NOTE: This keyboard command is not available under the Microsoft® Windows NT® and IBM® OS/2® operating systems. q A secondary cache of 512 KB of static random-access memory (SRAM) included within the single-edge contact (SEC) cartridge, which also contains the microprocessor. System memory that can be increased up to 768 megabytes (MB) by installing 32-, 64-, 128-, or 256-MB synchronous dynamic RAM (SDRAM) dual in-line memory modules (DIMMs) in the three DIMM sockets on the system board. The system also supports both error checking and correction (ECC) and nonparity DIMMs. See "System Memory" for details. Self-Monitoring and Analysis Reporting Technology II (SMART II) support, which warns you at system startup if your hard-disk drive has become unreliable. To take advantage of this technology, you must have a SMART II-compliant hard-disk drive in your computer. All hard-disk drives shipped with OptiPlex GX1 systems are SMART II-compliant. A basic input/output system (BIOS), which resides in flash memory and can be upgraded by diskette or remotely over a network, if required. Full compliance with PCI specification 2.1. Full Plug and Play version 1.0a capability, which greatly simplifies the installation of expansion cards. Plug and Play support included in the system BIOS allows you to install Plug and Play expansion cards without setting jumpers or switches or performing other configuration tasks. Also, because the system BIOS is stored in flash memory, it can be updated to support future enhancements to the Plug and Play standard. Wakeup On LAN capability, which, when enabled in the System Setup program, allows the system to be turned on from a server management console. Wakeup On LAN capability also allows remote computer setup, software downloading and installation, file updates, and asset tracking after hours and on weekends when network traffic is at a minimum. Universal Serial Bus (USB) capability, which can simplify connecting peripheral devices such as mice, printers, and computer speakers. The USB connectors on your computer's back panel, which are enabled by default, provide a single connection point for multiple USB-compliant devices.

ENERGY STAR® Compliance Certain configurations of Dell computer systems comply with the requirements set forth by the Environmental Protection Agency (EPA) for energy-efficient computers. If the front panel of your computer bears the ENERGY STAR® Emblem (see Figure 2), your original configuration complied with these requirements and all ENERGY STAR® power management features of the computer are enabled. To disable or change the operation of these features, you must change the setting for the Power Management option in the System Setup program. file:///C|/temp/dell/docs/9030t/intro.htm (10 of 11)12/1/2008 12:54:34 PM Introduction: Dell OptiPlex GX1 Small-Form-Factor System User's Guide NOTES:As an ENERGY STAR® Partner, Dell Computer Corporation has determined that this product meets the ENERGY STAR® guidelines for energy efficiency. Any Dell computer bearing the ENERGY STAR® Emblem is certified to comply with EPA ENERGY STAR® requirements as configured when shipped by Dell. Any changes you make to this configuration (such as installing additional expansion cards or drives) may increase the system's power consumption beyond the limits set by the EPA's ENERGY STAR® Computers program. Figure 2. ENERGY STAR Emblem The EPA's ENERGY STAR® Computers program is a joint effort between the EPA and computer manufacturers to reduce air pollution by promoting energy-efficient computer products. The EPA estimates that use of ENERGY STAR® computer products can save computer users up to two billion dollars annually in electricity costs. In turn, this reduction in electricity usage can reduce emissions of carbon dioxide, the gas primarily responsible for the greenhouse effect, and sulfur dioxide and nitrogen oxides, which are the two primary causes of acid rain. Computer users can also help to reduce electricity usage and its side effects by turning off their computer systems when they are not in use for extended periods of time, particularly at night and on weekends.

After you correctly connect all the cables to your system and turn it on, see the setup guide for your operating system to complete its installation. When the operating system is installed, you can connect peripheral devices such as a printer or install application programs not already installed by Dell. Connecting Peripheral Devices Figure 1 shows the connectors on the back of your computer for attaching external devices. Figure 1. I/O Ports, Connectors, and Indicators file:///C|/temp/dell/docs/9030t/setup.htm (1 of 15)12/1/2008 12:54:36 PM Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide 1 Parallel port connector 2 Mouse connector 3 USB connectors 4 Link integrity indicator (see "Integrated NIC Connector") 5 Activity indicator (see "Integrated NIC Connector") 6 Audio connectors 7 Integrated NIC connector 8 Video connector 9 Serial port 2 connector 10 Keyboard connector 11 Serial port 1 connector When you connect external devices to your computer's back panel, follow these guidelines: q 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) port or connector to operate properly. Also, external devices like a mouse or printer usually require you to load device drivers into system memory before they will work. q 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.) NOTICE: When you disconnect external devices from the back of the computer, file:///C|/temp/dell/docs/9030t/setup.htm (2 of 15)12/1/2008 12:54:36 PM Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide wait 5 seconds after turning off the computer before you disconnect any devices to avoid possible damage to the system board. Parallel Port Connector The integrated parallel port uses a 25-pin D-subminiature connector on the computer's back panel. This I/O port sends data in parallel format (where eight data bits, or one byte, are sent simultaneously over eight separate lines in a single cable). The parallel port is used primarily for printers. The default designation of your computer's integrated parallel port is LPT1. Port designations are used, for example, in software installation procedures to identify the port to which your printer is attached, thus telling your software where to send its output. (An incorrect designation prevents the printer from printing or causes scrambled print.) NOTE: The integrated parallel port is automatically disabled if the system detects an installed expansion card containing a parallel port configured to the same address as specified in the Parallel Port option in the System Setup program. Mouse Connector Your system uses a Personal System/2 (PS/2)-compatible mouse. The mouse cable attaches to a 6-pin miniature Deutsche Inductive Norm (DIN) connector on the back panel of your computer. Turn off the computer and any attached peripherals before connecting a mouse to the computer. A PS/2-compatible mouse works as does an industry-standard serial mouse or bus mouse except that it has its own dedicated connector, which frees up the serial ports and does not require an expansion card. Mouse driver software gives the mouse priority with the microprocessor by issuing interrupt request (IRQ) 12 whenever a new mouse movement is made. The drivers also pass along the mouse data to the application that is in control. USB Connectors Your system contains two Universal Serial Bus (USB) connectors for attaching USB-compliant devices. USB-compliant devices are typically peripherals such as keyboards, mice, printers, and computer speakers. If you reconfigure your hardware, you may need pin number and signal information for the USB connectors. Click one of the pins in the illustration for information on a particular signal. Integrated NIC Connector Your system has an integrated 10/100-megabit-per-second (Mbps) 3Com® Peripheral Component Interconnect (PCI) 3C905B-TX Ethernet network interface controller (NIC). The NIC provides all the functions of a separate network expansion card and supports both the 10BASE-T and 100BASE-TX Ethernet standards. file:///C|/temp/dell/docs/9030t/setup.htm (3 of 15)12/1/2008 12:54:36 PM Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide The NIC includes a Wakeup On LAN feature that enables the computer to be started by a special local area network (LAN) signal from a server management console. Wakeup On LAN provides remote computer setup, software downloading and installation, file updates, and asset tracking after hours and on weekends when LAN traffic is typically at a minimum. The NIC connector on the computer's back panel has the following indicators: q A yellow activity indicator flashes when the system is transmitting or receiving network data. (A high volume of network traffic may make this indicator appear to be in a steady "on" state.) A dual-colored link integrity indicator, which lights up green when there is a good connection between a 10Mbps network and the NIC, or it lights up orange when there is a good connection between a 100-Mbps network and the NIC. When the green indicator is off, the computer is not detecting a physical connection to the network. q Audio Connectors You can use the microphone jack to attach a standard personal computer microphone. Connect the audio cable from the microphone to the microphone jack. The microphone input is a monaural source with maximum signal levels of 89 millivolts root-mean-squared (mVrms). You can use the line-out jack to attach most computer speakers. The line-out jack is amplified, so speakers with integrated amplifiers are not required. Connect the audio cable from the speakers to this jack. You can use the line-in jack 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 on the back of your computer. Video Connector The system uses a 15-pin high-density D-subminiature connector on the back panel for attaching a video graphics array (VGA)-compatible monitor to your system. Serial Port Connectors The serial ports use 9-pin D-subminiature connectors on the back panel. These ports support devices such as external modems or plotters that require serial transmission (sending one bit of data at a time over one line). The default designations for these integrated serial ports are COM1 for serial port 1 and COM2 for serial port 2. Port designations are used in software installation procedures to identify the port used by a device--for example, specifying the port used by a modem when installing communications software. The system contains a reconfiguration feature to reassign the serial port's designation if you add an expansion card containing a serial port using this designation. file:///C|/temp/dell/docs/9030t/setup.htm (4 of 15)12/1/2008 12:54:36 PM Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide If you set the system's integrated serial ports to Auto in the System Setup program and add an expansion card containing a serial port configured to a specific designation, the computer automatically maps (assigns) the integrated ports to the appropriate COM setting as necessary. Before you add a card with a serial port, check the documentation that accompanied your software to make sure that the software can be mapped to the new COM port designation. Keyboard Connector Your system uses a PS/2-style keyboard. The keyboard cable attaches to a 6-pin miniature DIN connector on the back panel of your computer. Network Cable Requirements Your computer's NIC connector (an RJ45 connector located on the back panel) is designed for attaching an unshielded twisted pair (UTP) Ethernet cable. Press one end of the UTP cable into the NIC connector until the cable snaps securely into place. Connect the other end of the cable to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending on your network configuration. Controls and Indicators Figure 2 shows the controls and indicators on the front panel of your computer. Figure 2.

If the chassis has been opened, the setting changes to Detected and the following message is displayed during the boot sequence at system start-up: Alert! Cover was previously removed. Use the the Chassis Intrusion options in the System Setup program to reset the alarm so that future intrusions are detected. Security Cable Slot and Padlock Ring On the back of the computer are a security cable slot and padlock ring (see Figure 3) for attaching commercially available antitheft devices. (The padlock ring is recessed inside the cover.) Security cables for personal computers usually include a segment of galvanized cable with an attached locking device and key. To prevent unauthorized removal of your computer, loop the cable around an immovable object, insert the locking device into the security cable slot on the back of your computer, and lock the device with the key provided. Complete instructions for installing this kind of antitheft device are usually included with the device. NOTE: Antitheft devices are of differing designs. Before purchasing such a device, make sure it works with the cable slot on your computer. The padlock ring allows you to secure the computer cover to the chassis to prevent unauthorized access to the inside of the computer. To use the padlock ring, insert a commercially available padlock through the ring and then lock the padlock. Figure 3.

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, operate your system only with system password protection. You can assign a system password, as described in "Assigning a System Password," whenever you use the System Setup program. After a system password is assigned, only those who know the password have full use of the system. When the System Password option is set to Enabled, the computer system prompts you for the system password just after the system boots. See "Using Your System Password to Secure Your System" for more information. To change an existing system password, you must know the password (see "Deleting or Changing an Existing System Password"). If you assign and later forget a system password, you must remove the computer cover to change a jumper setting that disables the system password feature (see "Disabling a Forgotten Password"). Note that you erase the setup password at the same time. NOTICE: If you leave your system running and unattended without having a system password assigned, or if you leave your computer 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 System Password Before you can assign a system password, you must enter the System Setup program and check the System Password option. file:///C|/temp/dell/docs/9030t/setup.htm (9 of 15)12/1/2008 12:54:36 PM Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide When a system password is assigned, the setting shown in System Password is Enabled. When the system password feature is disabled by a jumper setting on the system board, the setting shown is Disabled by Jumper. You cannot change or enter a new system password if either of these options is displayed. When no system password is assigned and the password jumper on the system board is in the Enabled position (its default), the option shown for the System Password option is Not Enabled. Only when System Password is set to Not Enabled can you assign a system password, using the following procedure: 1. Verify that Password Status is set to Unlocked. 2. Highlight System Password, and then press the left- or right-arrow key. The option heading changes to Enter Password, followed by an empty 32-character field in square brackets. 3. Type your new system password. You can use up to 32 characters in your password. As you press each character key (or the spacebar for a blank space), a placeholder appears in the field. The password assignment operation recognizes keys by their location on the keyboard, without distinguishing between lowercase and uppercase characters. For example, if you have an M in your password, the system recognizes either M or m as correct. Certain key combinations are not valid. If you enter one of these combinations, the speaker emits a beep. To erase a character when entering your password, press the key or the left-arrow key. NOTE: To escape from the field without assigning a system password, press the key or the key combination to move to another field, or press the key at any time prior to completing step 5. 4. Press . If the new system password is less than 32 characters, the whole field fills with placeholders. Then the option heading changes to Verify Password, followed by another empty 32-character field in square brackets. 5. To confirm your password, type it a second time and press . The password setting changes to Enabled. Your system password is now set; you can exit the System Setup program and begin using your system. Note, however, that password protection does not take file:///C|/temp/dell/docs/9030t/setup.htm (10 of 15)12/1/2008 12:54:36 PM Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide effect until you reboot the system by pressing the reset button or by turning the system off and then on again. Using Your System Password to Secure Your System Whenever you either turn on your system or press the reset button, or when you reboot the system by pressing the key combination, the following prompt appears on the screen when Password Status is set to Unlocked: Type in the password and - press to leave password security enabled. - press to disable password security. Enter password: If Password Status is set to Locked, the following prompt appears: Type the password and press . After you type the correct system password and press , your system boots and you can use the keyboard and/or mouse to operate your system as usual. NOTE: If you have assigned a setup password (see "Using the Setup Password Feature"), the system accepts your setup password as an alternate system password. If you enter a wrong or incomplete system password, the following message appears on the screen: ** Incorrect password. ** Enter password: If you again enter an incorrect or incomplete system password, the same message appears on the screen. The third and subsequent times you enter an incorrect or incomplete system password, the system displays the following message: ** Incorrect password. ** Number of unsuccessful password attempts: 3 System halted! Must power down. The number of unsuccessful attempts made to enter the correct system password can alert you to an unauthorized person attempting to use your system. file:///C|/temp/dell/docs/9030t/setup.htm (11 of 15)12/1/2008 12:54:36 PM Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide Even after your system is turned off and on, the previous message is displayed each time an incorrect or incomplete system password is entered. NOTE: You can use Password Status in conjunction with System Password and Setup Password to further protect your system from unauthorized changes. Deleting or Changing an Existing System Password To delete or change an existing system password, perform the following steps: 1. Enter the System Setup program, and verify that Password Status is set to Unlocked. 2. Reboot your system to force it to prompt you for a system password. 3. When prompted, type the system password. 4. Press to disable the existing system password, instead of pressing to continue with the normal operation of your system. 5. Confirm that Not Enabled is displayed for the System Password option of the System Setup program. If Not Enabled appears in the System Password option, the system password has been deleted. If you want to assign a new password, continue to step 6. If Not Enabled is not displayed for the System Password option, press to reboot the system, and then repeat steps 3 through 5. 6. To assign a new password, follow the procedure in "Assigning a System Password." Using the Setup Password Feature Your Dell system is shipped to you without the setup password feature enabled. If system security is a concern, you should operate your system with setup password protection. You can assign a setup password, as described in "Assigning a Setup Password," whenever you use the System Setup program. After you assign a setup password, only those who know the password have full use of the System Setup program. See "Operating Your System With A Setup Password Enabled" for more information. To change an existing setup password, you must know the setup password (see "Deleting or Changing an Existing Setup Password"). If you assign and later forget a setup password, you need to remove the computer cover to change a jumper setting that disables the setup password feature (see "Disabling a Forgotten Password"). Note that you erase the system password at the same time. file:///C|/temp/dell/docs/9030t/setup.htm (12 of 15)12/1/2008 12:54:36 PM Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide Assigning a Setup Password You can assign a setup password only if Setup Password is set to Not Enabled. To assign a setup password, highlight Setup Password and press the left- or right-arrow key. The system prompts you to enter and verify the password. If a character is illegal for password use, the system emits a beep. NOTES: The setup password can be the same as the system password. If the two passwords are different, the setup password can be used as an alternate system password. However, the system password cannot be used in place of the setup password. After you verify the password, the Setup Password setting changes to Enabled. The next time you enter the System Setup program, the system prompts you for the setup password. A change to Setup Password becomes effective immediately (rebooting the system is not required). Operating Your System With a Setup Password Enabled If Setup Password is set to Enabled, you must enter the correct setup password before you can modify the majority of the System Setup options. When you start the System Setup program, the System Setup screen appears with Setup Password highlighted, prompting you to type the password. If you do not enter the correct password in three tries, the system lets you view, but not modify, the System Setup screen--with the following exceptions: q You can still modify the Date, Time, CPU Speed, Num Lock, and Speaker options. If System Password is not enabled and is not locked via the Password Status option, you can assign a system password (however, you cannot disable or change an existing system password). NOTE: You can use Password Status in conjunction with Setup Password to protect the system password from unauthorized changes. q Deleting or Changing an Existing Setup Password To delete or change an existing setup password, perform the following steps: 1. Enter the System Setup program. file:///C|/temp/dell/docs/9030t/setup.htm (13 of 15)12/1/2008 12:54:36 PM Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guide 2. Highlight Setup Password and press the left- or right-arrow key to delete the existing setup password. The setting changes to Not Enabled. 3.

Figure 3 in "Inside Your Computer" shows the location of the DIMM sockets on the system board. When you add system memory, you may install DIMMs in any socket. For optimum operation, Dell recommends that you install a DIMM in socket A first (closest to the processor) before installing a DIMM in another socket. Installing DIMMs To upgrade memory, perform the following steps. CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals, disconnect them from electrical outlets, and then wait at least 5 seconds before you remove the computer cover. Also, before removing the computer cover, see the other precautions in "Safety First--For You and Your Computer." 1. Remove the computer cover. 2. If necessary, remove any DIMMs that occupy sockets in which you plan to install the upgrade DIMMs. 3. Install the upgrade DIMMs. file:///C|/temp/dell/docs/9030t/memory.htm (1 of 4)12/1/2008 12:54:38 PM System Memory: Dell OptiPlex GX1 Small-Form-Factor System User's Guide a.
