Resumen del manual
Slide the CD-ROM drive assembly forward and up and out of the chassis. To replace a CD-ROM drive, perform the following steps: 1. Align the tabs on the bottom of the CD-ROM drive with the notches on the drive shelf, and slide the drive toward the back of the shelf until it snaps into place (see Figure 16). Figure 16. CD-ROM Drive Replacement 1 Tabs (2) 2 Notches (2) 2. Connect a power cable and an interface cable to the appropriate connectors on the back of the drive (see Figure 17). Figure 17. CD-ROM Drive Cable Attachment 1 Interface cable 2 Power cable 3 Power input connector 4 Interface connector Check all cable connections. Fold cables out of the way to provide airflow for the fan and cooling vents. 3. Replace the computer cover; reconnect your computer and peripherals to their electrical outlets, and turn them on. 4. Update your system configuration information. Set the Drive 1 option under Drives: Primary to Auto. See the online System User's Guide for more information. 5. Verify that your system works correctly by running the Dell Diagnostics (see the online System User's Guide for complete information). System Power Supply Figure 18. Power Supply Removal 1 Securing screw hole 2 AC power receptacle 3 Power supply 4 System board DC power connectors (2) 5 Drive DC power connectors (3) To remove the system power supply, perform the following steps: 1. Disconnect the AC power cable from the back of the power supply. 2. Disconnect the DC power cables from the system board and the drives. 3. Remove the screw on the side of the chassis that secures the power supply. 4. Remove the screw below the AC power receptacle at the back of the chassis. 5. Slide the power supply toward the center of the computer approximately 1 inch. 6. Lift the power supply up and out the computer chassis. Expansion-Card Cage Figure 19. Expansion-Card Cage Removal 1 Securing lever 2 Expansion-card cage 3 Tabs (2) 4 Hooks (2) To remove the expansion-card cage from the chassis, perform the following steps: 1. Remove the computer cover. NOTICE: Use a wrist grounding strap as explained in "Precautionary Measures." 2. Examine the cables connected to expansion cards through the back-panel openings, and disconnect any cables that will not reach to where the cage must be placed when it is removed from the chassis. 3. Locate the securing lever and rotate the lever upward until it stops in an upright position. 4. Lift the expansion-card cage up and out of the chassis. To replace the expansion-card cage into the chassis, perform the following steps: 1. With the securing lever in the upright position, align the tabs in the side of the expansion-card cage with the mating hooks on the left side of the chassis wall (see Figure 19). Slide the expansion-card cage into place. 2. Rotate the securing lever downward until it is flush with the top side of the chassis. Make sure that the riser board is fully seated in the RISER connector on the system board. 3. Reconnect any cables you removed in step 2 of the previous procedure. Riser Board Figure 20. PCI Riser Board 1 Auxiliary power indicator LED (AUX_LED) 2 Wakeup On LAN jumper (WOL) 3 PCI expansion slot 1 (PCI1) 4 PCI expansion slot 2 (PCI2) The chassis has a PCI riser board that has two PCI expansion-card connectors (see Figure 20). To remove the PCI riser board, perform the following steps: 1. Remove the expansion-card cage. 2. Remove the expansion cards installed in the slots. 3. Remove the screws securing the riser board to the expansion-card cage. 4. Lift the riser board off the expansion card cage. System Board Components The subsections that follow contain procedures for removing system board components, which are shown in Figure 21. Figure 21.
