[. . . ] Depending on the over-current protection of the power supply, certain Desktop Board components and/or traces may be damaged. Observe the precautions in "Before You Begin" on page 25. Place the card in the PCI Express x16 connector (Figure 16, A) and press down on the card until it is completely seated in the connector and the card retention notch snaps into place around the retention mechanism pin. Secure the card?s metal bracket to the chassis back panel with a screw (Figure 16, B). Figure 16. Installing a PCI Express x16 Card 38 Installing and Replacing Desktop Board Components Removing the PCI Express x16 Card Follow these instructions to remove the PCI Express x16 card from the connector: 1. Observe the precautions in "Before You Begin" on page 25. Remove the screw (Figure 17, A) that secures the card?s metal bracket to the chassis back panel. Push the card ejector lever down using the tip of a pencil or similar tool in the notch (Figure 17, B). This will release the card from the connector (Figure 17, C). Pull the card straight up. Figure 17. Removing a PCI Express x16 Card 39 Intel Desktop Board DG41RQ Product Guide Connecting the IDE Cable The IDE cable can be used to connect two IDE drives to the Desktop Board. The cable supports the ATA-66/100 transfer protocol. Figure 18 shows the correct installation of the cable. NOTES ATA-66/100 compatible cables are backward compatible with drives using slower IDE transfer protocols. If an ATA-66/100 disk drive and a disk drive using any other IDE transfer protocol are attached to the same cable, the maximum transfer rate between the drives may be reduced to that of the slowest drive. Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive. Observe the precautions in "Before You Begin" on page 25. Attach the cable end with the single connector (blue) to the Intel Desktop Board (Figure 18, A). Attach the cable end with the two closely spaced connectors (gray and black) to the drives (Figure 18, B). Figure 18. Connecting the IDE Cable 40 Installing and Replacing Desktop Board Components Connecting the Serial ATA (SATA) Cables SATA cables support the Serial ATA protocol. Each cable can be used to connect a single internal SATA drive to the Desktop Board. Observe the precautions in ?Before You Begin? [. . . ] Pay close attention to the following when reading the installation instructions for the host chassis, power supply, and other modules: ?Product certifications or lack of certifications External I/O cable shielding and filtering Mounting, grounding, and bonding requirements Keying connectors when mating the wrong connectors could be hazardous If the power supply and other modules or peripherals, as applicable, are not Class B EMC compliant before integration, then EMC testing may be required on a representative sample of the newly completed computer. 70 Regulatory Compliance Product Certifications Board-Level Certification Markings Intel Desktop Board DG41RQ has the product certification markings shown in Table 19.
