c . Low Profile PCI Express Card with Rigid Hold-down Bracket: If your workstation is
configured with a low profile PCI Express x16 card and a rigid, non-hinged hold-down bracket
(as shown in the following illustration), you must first remove screws 3, 4, and 5 and then remove
the bracket (2) before removing the card (1). Retain the screws for reinstallation of the bracket
and proceed to Step f. to remove the card. After you replace or reinstall a low profile PCI Express
x16 card, reverse this process to reinstall the hold-down bracket after inserting the card.
