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.
