Installation
WARNING! Computer parts can be severely damaged by static electricity.
Be sure that you are properly grounded before opening your computer
case. StarTech.com recommends that you wear an anti-static strap when
installing any computer component. If an anti-static strap is unavailable,
discharge yourself of any static electricity build-up by touching a large
grounded metal surface (such as the computer case) for several seconds.
Hardware Installation
1. Turn your computer off and any peripherals connected to the computer
(i.e. Printers, external hard drives, etc.). Unplug the power cable from the
rear of the power supply on the back of the computer and disconnect all

your computer system for details.
3. Locate an open expansion card slot on the rear of the computer case
