MMPC Model 10/20 (250-1640/41) Setting Up Faxback Doc. # 5414 This section explains how to set up and begin using your computer. To set up, you'll need to connect the keyboard and a monitor. You can also connect other external hardware, or "peripherals", such as a printer. To connect peripherals to your audio adapter, refer to "Setting Up Audio Options." Refer to the documentation for your operating system, application software, and peripherals as needed. Setting Up Your System > Caution: Place the computer near a properly grounded, easily accessible AC outlet. To ensure that the unit is adequately ventilated, position the keyboard and any peripherals at least 2 inches from the vents. Do not block the sides, front, or back of the computer. Follow these steps to set up your computer: 1. The voltage selector switch on the back panel enables you to set the computer for connection to a 110-120V AC or 220-240V AC outlet. If necessary, use a pen or similar object to change the setting of the voltage selector switch to match the voltage of your outlet. 2. Read the following information before connecting the power cord to the computer: * Do not use an outlet that powers heavy machinery such as copiers and office machines. If you must use an extension cord, use a grounded, multiple- outlet power strip. The combined length of the power and extension cords must not exceed the maximum length specified below. * For a 115V power source: Use a UL/CSA-listed cord set consisting of a minimum 18 AWG, type SVT or SJT three-conductor cord a maximum of 15 feet in length and a parallel blade, grounding-type attachment plug rated 10A, 125V. The power cord included with the computer meets these requirements. * For a 230V power source inside North America: Use a UL/CSA-listed cord set consisting of a minimum 18 AWG, type SVT or SJT three-conductor cord a maximum of 15 feet in length and a tandem blade, grounding- type attachment plug rated 10A, 250V. * For a 230C power source outside North America: Use a cord set consisting of a minimum 0.75mm cord and grounding-type attachment plug rated 10A, 250V. The cord set should have the appropriate safety approvals for the country in which the equipment will be installed and should be marked HAR. 3. Connect the power cord, keyboard, and monitor. > Note: You can connect any monochrome or color, fixed- or multiple-frequency, interlaced or non- interlaced VGA analog monitor. However, some video modes require specific monitor frequencies. For details, refer to the "SVGA Video" section. 4. Connect other peripherals included with your computer. Some of the connections show peripherals that must be purchased separately. > Note: If you purchased an IEC power cord, refer to "Connecting an IEC Power Cord." 5. See "Connecting a Printer or Other Parallel Device" and "Connecting a Modem or Other Serial Device" as needed. Connecting an IEC Power Cord The computer's IEC power connector is located on the back panel of the computer, near the power connector. Plug the power cord of your monitor (or other device) into the IEC power connector if you want to turn the device on and off when you press the computer's power button. If the device power cord does not fit, purchase an IEC power adapter from your computer dealer. Connecting a Printer or Other Parallel Device You can connect a printer or other parallel device to the parallel connector on the back of the computer. The setup utility lets you specify whether the parallel port allows unidirectional transfer (send data only) or bidirectional transfer (send and receive data). Refer to the "Utilities" section for information. > Note: Refer to an operating system manual to determine whether the operating system supports bidirectional operation. Connecting a Modem or Other Serial Device You can connect a serial device to each serial port on the back of the computer. After you connect serial devices, refer to the device documentation to determine whether you need to change the port configuration. Before changing the serial port configuration, refer to "Changing Jumper Settings" in the "Installing Optional Hardware" section and the "Utilities" section for more information. > Caution: If more than one device is configured to use the same interrupt, a device "conflict" can occur, resulting in operation problems. Refer to your option documentation to determine which interrupts a device can use. Installing Optional Hardware This section begins with reference information you may need to install hardware options. "Opening the Computer" gives instructions for removing the computer cover and various internal computer components." "Main Logic Board Layout" shows the locations of connectors and sockets on the main logic board. "Changing Jumper Settings" shows the locations of the main logic board jumper blocks and lists the jumper settings. The reference information is followed by instructions for installing the following hardware options: * upgrade processor * system memory * video memory * expansion adapters The section ends with instructions for replacing the CMOS RAM battery and closing the computer. Your computer dealer can arrange the installation of optional hardware that you choose not to install yourself. Opening the Computer To install internal hardware options, you must open and close the computer. In some cases, you must also remove and reinstall internal components. Remove only the outer computer cover and the expansion adapter cover to perform any of the following tasks: * change the setting of the Upgrade Processor Support jumpers or On-Board Video jumpers * install an expansion adapter * install system memory * install video memory * install an upgrade processor If you need to replace the battery or reinstall jumpers, also remove the drive bay cover and the drive tray. Read the following instructions before opening the computer. > Caution: Static electricity can damage the electronic components in a computer. Before opening the computer, discharge any accumulated static electricity from your body by touching a grounded metal object. 1. Turn off the computer, monitor, and any other connected devices. Disconnect all cables from the computer. 2. Use a Phillips screwdriver to remove the two cover- counting screws as shown: 3. Pull the cover toward the front of the computer until the edge of the cover is at least 3 inches away from the computer's back panel. 4. Lift the cover away from the system unit: 5. Press down lightly on the expansion adapter cover. slide it away from the tab, toward the front of the computer: 6. Rotate the expansion adapter cover away from the computer. Remove the cover from the side slots at the bottom of the computer: 7. Lift the drive bay cover, and remove it from the side slots at the top of the computer: Removing the Drive Tray: The drive tray holds the factory-installed diskette drive, hard drive, and CD-ROM drive. Remove the drive tray to perform the following tasks: * replace the CMOS RAM battery * change the setting of the Clock Speed jumper, the Power Indicator/Hard Drive Activity Indicator jumper, the Serial Port Interrupt jumper, or the Parallel Port Interrupt jumper To remove the drive tray: 1. Place both hands under the drive tray. Firmly grasp the tray and lift it: > Caution: Handle the tray carefully to avoid damaging any electronic components. 2. Carefully turn over the tray: When you are ready to close the computer, refer to "Closing the Computer." Closing the Computer > Caution: Before closing the computer, be sure the internal cables are securely connected. Loose cable connections can damage the cables and the main logic board components. Be sure the cables do not cause mechanical interference. 1. If you removed the drive tray, locate the alignment flanges on the front of the drive tray. Carefully rotate the drive tray into position so that the tray's flanges fit behind the front edge of the computer > Caution: Pressing directly on the drives in the drive tray 9an damage the drives. Press on the drive tray edges to position the tray. Press the drive tray backward and downward into place. 2. Position the drive bay cover in the side slots at the top of the computer. Close the drive bay cover. 3. Place the expansion adapter cover in the side slots at the bottom of the computer. Close the expansion adapter cover, and insert the expansion adapter cover tabs into the slots in the drive bay cover. 4. Slide the expansion adapter cover backward to secure it under the tab. 5. Position the outer cover on the computer. Slide the cover onto the computer until it fits into place. 6. Install the two cover-mounting screws to secure the cover. 7. Reconnect all cables to the back of the computer. refer to the "Getting Started" section. (smc-02/02/94)
