Check the PCI Bracket

The standard PCI bracket to which the PCI Adapter is attached by

low-profile desktop, you need to replace the standard bracket

with the low-profile bracket for the PCI Adapter to fit the

computer case.

To replace the PCI bracket:

bracket. Save the screws to fasten the low-profile bracket later.

2 Replace the standard bracket with the low-profile bracket.

you removed in step 1.
