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 o 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
No driver installation is required for the compatible operating systems, as this adapter card is
natively supported, so the drivers are already installed.
