Adding or Replacing PCI/PCI-X Cards
007-4857-002 131
Note: If you are adding or replacing a half-height PCI card, skip ahead to step 6.
5. If the full-height card that you want to install does not fit in the carrier, follow these steps:
a. Loosen the three screws on the guide bar with a Phillips screwdriver (if your carrier uses
T8 Torx screws, you will need a Torx screw driver).
b. Adjust the carrier guide bar (also known as the alignment rail) up or down as necessary
(see Figure 6-17).
