Resumen del manual
7. Remove the memory modules. 8. Disconnect the hard-drive interface cables from the appropriate card: a. If this is a software RAID or external storage configuration system, remove the cables from the daughter card. b. If this is a hardware RAID system, remove the cables from the CERC SATA RAID controller. 9. If this is a software RAID or external storage configuration system, remove the daughter card. See your Installation and Troubleshooting Guide for more information. 10. Disconnect the control panel interface cable from the J7 connector on the system board. See Figure 1-2. 11. Remove all PCI expansion cards installed on the riser board. 12. Using a #2 Phillips screwdriver, loosen the two captive screws securing the riser board to the system board. 13. Disconnect the riser board from the system board card-edge connector. 14. Remove the fan assembly. See your Installation and Troubleshooting Guide for more information. 15. Remove the power supply. See your Installation and Troubleshooting Guide for more information. 16. Using a #2 Phillips screwdriver, loosen the captive screw that secures the system board tray to the chassis floor. See Figure 1-2. 17. Using the tab on the system board tray, slide the system board forward, toward the front of the system and lift the assembly up and out of the chassis. See Figure 1-2. 18. Lay the system board tray down on a smooth, nonconductive work surface. Figure 1-2. Removing the System Board and System Board Tray Installing the System Board Assembly 1. Unpack the new system board assembly. 2. Align the system board tray so that the tabs on the chassis floor slide into the notches in the system board tray. 3. Slide the system board tray backward until it stops. 4. Using a #2 Phillips screwdriver, tighten the captive screw that secures the system board tray to the chassis. See Figure 1-2. NOTE: After removing the memory modules, record the memory module socket locations to ensure proper installation. CAUTION: See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge. 5. Install the power supply. See your Installation and Troubleshooting Guide for more information. 6. Install the fan assembly. See your Installation and Troubleshooting Guide for more information. 7. Connect the riser board. 8. Using a #2 Phillips screwdriver, tighten the two captive screws that secure the riser board to the system board. 9. Install any PCI expansion cards that you removed. 10. If this is a software RAID or external storage configuration system, install the daughter card. See your Installation and Troubleshooting Guide for more information. 11. Connect the hard-drive interface cables: a. If this is a software RAID or external storage configuration system, connect the cables from the daughter card. b. If this is a hardware RAID system, connect the cables from the CERC SATA RAID controller. 12. Install the processor. 13. Install the heat sink. a. Using a lint-free cloth, remove the existing thermal grease from the processor and heat sink. b. Apply thermal grease evenly to the top of the processor. c. Align the holes on both sides of the heat sink with the heat-sink posts on the system chassis. 14. Orient the securing clips so that the rubber-coated tabs are toward the back of the chassis. 15. Lower the end opposite of the rubber-coated tab of each securing clip over the heat-sink post, and then slide the securing clip toward the heat-sink post until they snap onto the post. 16. While holding down the rubber-coated tab with one hand, push the latch on the securing clip toward the heat-sink post until it locks the clip onto the post. 17. Repeat step 15 and step 16 for the other securing clip. 18. Install the memory modules. 19. Connect the LED cable to the daughter card on software RAID or external storage configurations, or the CERC SATA RAID controller on hardware RAID systems. 20. Connect the control panel interface cable to the J7 connector on the system board. 21. Install the cooling shroud. 22. Close the system. a. Ensure that you did not leave tools or parts inside the system. b. Place the cover over the sides of the chassis, and slide the cover forward. c. Tighten the two captive screws at the back of the system to secure the cover. 23. Reconnect the system to the electrical outlet, and turn on the system. 24. Replace the bezel. a. Push the latches on the bezel inward. b. Place the panel on the front of the system and release the latches. Back to Contents Page NOTE: Use the same heat sink that you removed from the processor. NOTE: If the securing clips are installed so that the rubber-coated tabs are toward the front of the system, the cooling shroud cannot be installed correctly. NOTE: Install the memory modules as noted in step 7 of the procedure in "Removing the System Board Assembly." NOTE: When installing the cooling shroud, ensure that the two tabs on the cooling shroud are ins...
