Installation

WARNING! PCI cards, like all computer equipment, can be severely damaged by static 

electricity. Be sure that you are properly grounded before opening your computer 

case or touching your PCI card. 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. Also be careful to 

handle the PCI card by its edges and not the gold connectors.

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 peripheral devices.

2.  Remove the cover from the computer case.  Refer to documentation for your 

computer system for details.

3.  Locate an open PCI or PCI-X slot and remove the metal cover plate on the rear of the 

computer case.
