You must install the software before installing the hardware.

Before you install the PXIe-2527, refer to the guidelines in Maintain Forced-Air Cooling Note to Users to ensure that the PXIe-2527 can cool itself effectively.

Complete the following steps to install your PXIe-2527 into the chassis.

  1. Ensure the AC power source is connected to the chassis before installing the PXIe-2527.
    The AC power cord grounds the chassis and protects it from electrical damage while you install the PXIe-2527.
  2. Power off the chassis.
  3. If the NI PXI/PXI Express chassis has multiple fan speed settings, ensure that the fans are set to high.
  4. Position the chassis so that inlet and outlet vents are not obstructed.
    For more information about optimal chassis positioning, refer to chassis documentation.
  5. Remove the black vinyl caps from all the captive screws on the front panel of the PXIe-2527.
  6. Identify a supported slot in the NI PXI/PXI Express chassis.
    Refer to the following table to determine what slots support PXIe-2527 if you are using a NI PXI Express chassis. Refer to the chassis documentation for details.

    NI PXI Peripheral Slot

    NI PXI Express Peripheral Slot

    NI PXI Express Hybrid Peripheral Slot

    NI PXI Express System Timing Slot

    Tip If you plan to use the optional PXIe-6674T Timing and Synchronization Module, reserve the PXI Express system timing slots for its placement in the chassis.
  7. Remove the filler panel of an unused PXI/PXI Express slot.
  8. Touch any metal part of the chassis to discharge static electricity.
  9. Ensure that the ejector handle of the PXIe-2527 is in the unlatched (down) position and swings freely.
  10. Holding the PXIe-2527 by the ejector handle, slide it into the empty slot, ensuring that the card engages with the card guides in the chassis.
  11. When you begin to feel resistance, pull up on the ejector handle to latch the PXIe-2527.
  12. Secure the PXIe-2527 front panel to the chassis using the front-panel mounting screws.
    Note Tightening the top and bottom mounting screws increases mechanical stability and also electrically connects the front panel to the chassis, which can improve the signal quality and electromagnetic performance.
  13. Cover all empty slots using either filler panels (standard or EMC) or slot blockers with filler panels, depending on your application.
    Note For more information about installing slot blockers and filler panels, go to ni.com/r/pxiblocker.
  14. Power on the chassis.
