To install the USB 3 interface card

1. Turn off your computer and all connected peripherals, such as the monitor and printer. Make sure that the computer is unplugged.
2. Remove the PC's case according to the instructions provided in the PC's user manual.
3. Select a free free PCIe  expansion slot, and remove the corresponding extension cover. For details about PCIe slots, see see PCIe slot properties in  in Set up analog cameras
4. Unpack the USB 3 interface card, place it into the slot, and press it carefully into position. If the card does not fit into place easily, remove it and repeat the operation.
5. Fix the card to the chassis and re-fit the computer's cover.
   If you have a 4-port Fresco Logic U3X4-PCIE4XE111 rev 1.1 board, make sure the board receives power from the PC. Connect the power connector on the board (Molex/IDE male 4-pin DC) to one of the power supplies inside the PC. Connector types vary between computers. Many computers have a SATA 15-pin power connector. Use an adapter cable with a 4-pin female Molex connector at one end and a SATA 15-pin connector at the other end.
