IDC Header Pinout
The internal IDC header connectors can be used in place of some / all external ports
on this card. They are labeled S1 – S4 and each corresponds to the external port of
the same number (marked on the breakout cable). Do not connect the internal and
external port of the same number simultaneously.
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 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 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. Refer to 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.
4. Gently insert the card into the open PCI Express slot and fasten the card’s bracket to
the rear of the case.
NOTE: If installing the card into a low profile system, replacing the pre-installed
standard profile bracket with the included low profile bracket may be necessary.
