Dell 1900 owner manual Removing an Expansion Card

5Remove the filler bracket on the slot you will be using.

NOTE: Keep this bracket if you need to remove the expansion card. Filler brackets must be installed over empty expansion-card slots 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.

6Align the expansion card with the card-edge guides and insert the expansion card firmly into the expansion-card connector until the card is fully seated.

NOTE: Ensure that the expansion-card bracket is also inserted into the securing slot on the back of the expansion-card cage.

7Close the expansion-card retainer. See Figure 3-9.

8If applicable, reinstall the expansion-card stabilizer:

a Insert the two round tabs on the stabilizer into the stabilizer pivot slots. See Figure 3-9.

b Rotate the end of the stabilizer down toward the front of the system until the latch clicks into place against the chassis.

9Connect any internal or external cables to the expansion card.

10Close the system. See "Closing the System" on page 48.

11Connect the power cable to the power supply and the power outlet.

4Disconnect any internal or external cables that are connected to the expansion card.

5Open the expansion-card retainer adjacent to the slot. See Figure 3-9.

6Grasp the expansion card and carefully remove it from the socket connector.

7If you are permanently removing the card, replace the metal filler bracket over the empty card-slot opening.

NOTE: Filler brackets must be installed over empty expansion-card slots to maintain 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.
