Notice To prevent damage to the NI 5646R-G caused by ESD or contamination, handle the module using the edges or the metal bracket.
Note

You must install the software before installing the hardware.

Before you install the hardware, refer to the guidelines in the Maintain Forced-Air Cooling Note to Users included with the module to ensure that the device can cool itself effectively. This document is also available at ni.com/manuals.

The NI 5646R-G is a three-slot module with two backplane connectors. The module must be installed into three adjacent chassis slots, and the left two slots must be PXI Express compatible.

  1. Ensure the AC power source is connected to the chassis before installing the module.
    The AC power cord grounds the chassis and protects it from electrical damage while you install the module.
  2. Power off the chassis.
  3. Inspect the slot pins on the chassis backplane for any bends or damage prior to installation. Do not install a module if the backplane is damaged.
  4. If the chassis has multiple fan speed settings, ensure the fans are set to the highest setting.
    Note Inadequate air circulation could cause the temperature inside the chassis to rise above the optimal operating temperature for the device, potentially causing thermal shutdown, shorter lifespans, or improper performance.
  5. Position the chassis so that inlet and outlet vents are not obstructed.
    Caution Do not disconnect the cable that connects CAL IN to CAL OUT. Removing the cable from or tampering with the CAL IN or CAL OUT front panel connectors voids the product calibration and specifications are no longer warranted.
  6. Remove the black plastic covers from all the captive screws on the module front panel.
  7. Identify a supported slot in the chassis. The following figure shows the symbols that indicate the slot types.

    3. PXI Express Hybrid Peripheral Slot
    4. PXI Express System Timing Slot
    5. PXI Express Peripheral Slot
    The NI 5646R-G can be placed in PXI Express peripheral slots, PXI Express Hybrid peripheral slots, or PXI Express system timing slots.
  8. Touch any metal part of the chassis to discharge static electricity.
  9. Ensure that the ejector handle is in the unlatched (downward) position.
  10. Hold the module by the edges and slide it into the empty compatible slots. Ensure the base engages with the guides in the chassis.

  11. Latch the module in place by pulling up on the ejector handle.
  12. Secure the module 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.
