  2. Install the PCIe switch board heat sink.
    1. Align the PCIe switch board heat sink with the four screw holes on the PCIe switch board; then, gently place the PCIe switch board heat sink onto the PCIe switch board.
    2. Follow the screw sequence specified on the heat-sink label, and turn the four screws clockwise a few turns until the screw threads engage in the PCIe switch board.
    3. Follow the screw sequence specified on the heat-sink label, and fully tighten the four screws to secure the PCIe switch board heat sink.
    Note
    Loosen or tighten the screws with a torque screwdriver set to the proper torque. For reference, the torque required for the screws to be fully loosen or tighten is 0.9 newton-meters, 8 inch-pounds.
