Installation

WARNING! PCI Express 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

Express 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 Express card by

its edges and not the gold connectors.

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 peripheral devices.

2. Remove the cover from the computer case. See documentation for

your computer system for details.

3. Locate an open PCI Express slot and remove the metal cover plate

on the rear of the computer case (Refer to documentation for your

computer system for details.). Note that this card will work in PCI

Express slots of additional lanes (i.e. x4, x8 or x16 slots).

4. Insert the card into the open PCI Express slot and fasten the bracket

to the rear of the case.

5. Place the cover back onto the computer case.

6. Insert the power cable into the socket on the power supply and

reconnect all other connectors removed in Step 1.

Driver Installation

Windows 2000/XP/Server 2003

insert the Driver CD into your CD/DVD drive. If you are prompted

to connect to Windows Update, please select the “No, not this time”

2. When prompted to insert the disc, insert the Driver CD that

came with the card, into your CD/DVD drive and Windows will

automatically proceed to search the CD.

3. If a Windows Security dialog window appears, click the “Install this

driver software anyway” option to proceed.

4. Once the driver is installed, click the Close button.

Verifying Installation
