WARNING! PCI Express cards, like all computer equipment, can be se-

verely damaged by static electricity. Be sure that you are properly ground-

ed before opening your computer case or touching your card. StarTech.

com recommends that you wear an anti-static strap when installing any

computer component. If an anti-static strap is unavailable, discharge your-

self 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 card by its edges and not the gold connectors.
