Your computer has two PCIe x1 card slots, one PCIe x4 card slot (negotiable link width x4, x1), and one PCIe
x16 graphics card slot.
To install or replace a PCIe card, do the following:
1. Prepare your computer. See "Preparing your computer and removing the computer cover" on page 57.
2. Rotate the PCIe card retainer to the open position. Depending on whether you are installing or replacing
a PCIe card, do one of the following:
• If you are installing a PCIe card, remove the appropriate metal slot cover.
• If you are replacing an old PCIe card, grasp the old card and gently pull it out of the slot.

Notes:
– The card fits tightly into the slot. If necessary, alternately move each side of the card a small
amount until the card is removed from the slot.
– If the card is held in place by a retaining latch, disengage the card retaining latch on the PCIe card
slot. Then grasp the card and gently pull it out of the slot.
