Notes:
a. The card fits tightly into the card slot. If necessary, alternate moving each side of the card a small
amount until it is removed from the card slot.
b. If the card is held in place by a retaining latch, disengage the card retaining latch in either of the
two ways illustrated, depending on the retaining latch on the PCI card slot. Grasp the card and
gently pull it out of the slot.
