JP3 and JP2 - Serial port power
These two jumpers are used to provide external power to the two breakout cables or
the 16 serial ports. JP3 enables or disables power over ports 1 to 8, and JP2 enables or
disables power over ports 9 to 16. When enabled, the card connects DC power to pin 9
of the DB9 port(s).

Hardware installation
Install the low-prole bracket
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 low-prole bracket instead.
1. Remove the four screw locks that are securing the two VHDCI-68 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 VHDCI-68 port hole with the card’s VHDCI-68 ports.
4. Insert the VHDCI-68 ports into the VHDCI-68 port hole on the low-prole bracket
using the four screw locks from step 1.
5. Insert the four screw locks from step 1 and tighten them into place on the 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.
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 included
low-prole bracket. See“Install the low-prole bracket” for instructions on how to do
this.
