Resumen del manual
2. Remove the system cover and support beam. 3. Remove the cooling shroud. 4. Remove the fan. 5. Disconnect the DC power cable from the system board (POWER). 6. Record the locations and remove all internal cables attached to the system board. 7. Remove all external peripheral cables from their connectors at the back of the system. 8. Remove the expansion cards. 9. Remove the hex-head Phillips screw securing the system board to the back of the system chassis (see Figure 16). Figure 16. Removing the System Board Securing the Hardware CAUTION: Read the safety instructions in your System Information document. 1 Screws (3) 2 Nonredundant power supply CAUTION: Avoid touching the cable connectors on the power supply. Wait 10 to 20 seconds after disconnecting the power cord before removing the power supply or coming into contact with its cable connectors. CAUTION: Read the safety instructions in your System Information document. 10. Lift the front of the system board to clear the mounting standoffs and slide the system board toward the front of the system chassis about 6.3 mm (0.25-inch) see Figure 17. 11. Carefully lift the system board up and out of the chassis. Be sure to lift evenly and not twist the system board. Figure 17. System Board Removal 12. Place the system board on a smooth, antistatic surface. 13. Remove the microprocessor. 15. Remove the memory modules. To replace the system board, perform the following steps: 1. Press the system board evenly into all the grounding tabs for the I/O ports on the back of the chassis and then, slide it to the rear about 6.3 mm (0.25- inch) so that the mounting standoffs protrude through the system board. 2. Tighten the hex-head Phillips screw to secure the system board to the back of the chassis. 3. Install the memory modules. 4. Install the microprocessor. 5. Check to ensure the system board jumpers and switches are set to the same settings as the board you removed. 6. Install the expansion cards. 7. Connect all internal power and signal interface cables. 8. Install the fan. 9. Install the cooling shroud. 10. Replace the system cover and support beam. 11. Connect external peripheral cables. 12. Connect the power to the system and turn the system on. System Board Features Figure 18 defines the system board features. Use this figure when replacing your system board or components that attach to the system board. Figure 18. System Board Features 1 System board 2 Phillips-head screw 1 Mounting standoffs Expansion Cards The system has five fixed expansion-card sockets. Figure 19. Expansion Card Removal Expansion Card Removal To remove an expansion card, perform the following steps. 1. Remove the system cover and support beam. 2. Disconnect any cables connected to the expansion card. 3. Remove the screw from the card bracket (see Figure 19). 4. Grasp the card by its top corners, and lift it from the system board. 5. If you are removing the card permanently, install a metal filler bracket over the empty card-slot opening. 6. Replace the system cover and support beam, and then reconnect the system and peripherals to their power sources and turn on the system. To install an expansion card, perform the following steps: 1. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet. 2. Remove the system cover. See the documentation that came with the expansion card for information on configuring the card, making internal connections, or otherwise customizing the card for your system. 1 Keyboard (KY) and mouse (MS) connectors 2 Fan connector (SYS_FAN2) 3 Microprocessor (CPU) 4 Memory module sockets (4) DIMM_x 5 Power connector (POWER) 6 Diskette drive cable connector (FDD) 7 Front panel connector (FRONT PANEL) 8 Primary IDE connector (PRIMARY IDE) 9 Primary IDE connector (Secondary IDE) 10 System jumpers (J12) 11 System battery connector (BATTERY) 12 expansion card slots (5) (SLOT_n) 13 RJ45 NIC connector (LAN1) 14 USB connector (2) (USBn) 15 Video connector (VGA) 16 Parallel port (LPT) 17 Serial port (COM1) connector CAUTION: Read the safety instructions in your System Information document. 1 Filler brackets 2 Card guide 3 System board connector 4 Card connector 5 Expansion card NOTE: Installing a filler bracket over an empty expansion slot is necessary to maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the system and aid in proper cooling and airflow inside the system. CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document. 3. Unscrew and remove the filler bracket for the card slot you want to use. Save the screw to use when installing the expansion card later in this procedure (see Figure 19). 4. Align the cutout on the bottom of the card with the crossbar in the system board connector. Gently rock the card into the connector until it is fully seated (see Figure 19). If the card is full-leng...
