6.
Secure the module mounting bracket to the computer back panel rail.
Note
Tightening the top mounting screw increases mechanical stability and
also electrically connects the front panel to the chassis, which can improve the
signal quality and electromagnetic performance.
7.
Some computer manufacturers use a securing lever made of plastic to secure PCI devices;
such a lever is unacceptable and must be removed. Use the screw provided in the kit to
screw down the device. Otherwise, you must use a different computer chassis.
8.
Replace any access panels on the computer case.
9.
Power on your computer.
10. Verify that spread-spectrum clocking is enabled in the PC BIOS. For information about
how to verify this setting, refer to the PC user documentation
Note
For SMC-based devices, spread-spectrum clocking varies the clock
signal to spread the timing clock signal over a small frequency range. Disabling
spread-spectrum clocking may affect the accuracy of device specifications.
