Removing an Expansion-Card Riser CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product. 1 Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet. 2 Open the system. See "Opening the System" on page 89. 3 To remove the expansion-card riser, press the release tabs toward each other and lift the expansion-card riser out of the system. See Figure 3-23. 4 Press the tabs toward each other and open the expansion-card latch. See Figure 3-22. 5 Grasp the expansion-card by its edges, and carefully remove it from the expansion-card connector on the riser. 6 If you are removing the expansion-card riser permanently, install the panel in the system. See Figure 3-21. NOTE: You must install the panel over an empty expansion slot 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. 7 Close the system. See "Closing the System" on page 90. 8 Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals. Installing System Components 133
