Hardware installation
Install the low-prole brackets
The serial card can be installed in a low-prole (half-height) or a full-prole computer.
The full-prole bracket comes preinstalled on the card, but if you have a small form-
factor computer, you can install the two low-prole brackets instead.
1. Remove the four screw locks that are securing the DB9 serial ports to the full-prole
bracket.
2. Remove the full-prole bracket from the card.
3. Align the low-prole bracket’s DB9 port holes with the DB9 ports on the card.
4. Insert one DB9 serial port into the DB9 port hole on each of the two low-prole
brackets using the screw locks from step 1.
5. Insert the two screw locks from step 1 and tighten them into place on each low-
prole bracket.
Install the PCIe Card
Warning! PCIe cards can be severely damaged by static electricity. If an anti-static strap
isn’t available, discharge any built-up static electricity by touching a large grounded
metal surface for several seconds.
1. Turn o your computer and any devices or peripherals that are connected to it, such
as printers or external storage devices.
2. Unplug the power cable from the back of your computer.
3. Disconnect any peripheral devices that are connected to your computer.
4. Remove the cover from your computer case. Consult the documentation that came
with your computer for details about how to do this safely.
5. Locate an open PCIe slot and remove the corresponding metal cover plate from
the back of your computer case. Consult the documentation that came with your
computer for details about how to do this safely. This card works in PCIe slots of x1,
x4, x8, or x16 lanes.
6. Gently insert the card into the open PCIe slot and fasten the bracket to the back
of the case. For low-prole installations, two open slots on your computer case are
required, one for the PCIe card, and one additional open slot for the second low-
prole bracket.
Note: If you install the card into a low-prole (small form-factor) desktop system,
it might be necessary to replace the preinstalled full-prole bracket with the two
included low-prole installation brackets. See “Install the low-prole brackets”for
instructions on how to do this.
