To install the board in a PC chassis:
  1. On the VCU128 board, remove the five screws retaining the five rubber feet and standoffs, and the PCIe bracket. Reinstall the PCIe® bracket using two of the previously removed screws.
  2. Power down the host computer and remove the power cord from the PC.
  3. Open the PC chassis following the instructions provided with the PC.
  4. The VCU128 board has a large cooling fan that requires two adjacent PCIe slots. Ensure the slot adjacent to the front of the board is free of obstructions.
  5. Remove the PCIe expansion slot cover (at the back of the chassis) which aligns with the VCU128 PCIe bracket, by removing the screws on the top and bottom of the cover.
  6. Plug the VCU128 board into the appropriate open slot.
  7. Install the top mounting bracket screw into the PC expansion cover retainer bracket to secure the VCU128 board in its slot.
  8. If using the ATX supply 4-pin (1x4) peripheral connector, connect power to the VCU128 board using the ATX power supply adapter cable as shown in the previous figure.
    1. Plug the 6-pin 2 x 3 Molex connector end of the adapter cable into J16 on the VCU128 board.
    2. Plug the 4-pin 1 x 4 peripheral power connector from the ATX power supply into the 4-pin adapter connector end of the cable.
      CAUTION:
      Do NOT plug a PC ATX power supply 6-pin connector into J16 on the VCU128 evaluation board. The ATX 6-pin connector has a different pinout than J16. Connecting an ATX 6-pin connector into J16 damages the VCU128 evaluation board and voids the board warranty.
    3. Slide the VCU128 board power switch SW5 to the ON position. The PC can now be powered on.
  9. If using the ATX supply 8-pin (2x4) PCIe power connector, plug the connector into VCU128 board JP1. The PC can now be powered on.
