This section contains instructions for installing the PXIe-7890 or PXIe-7891 module in a PXI Express chassis. Refer to your chassis user manual for specific instructions and warnings. To install the module, complete the following steps:

  1. Connect the AC power source to the PXI Express chassis before installing the module. The AC power cord grounds the chassis and protects it from electrical damage while you install the module.
  2. Ensure that the chassis is powered off.
  3. Inspect the slot pins on the chassis backplane for any bends or damage prior to installation. Do not install any module if the backplane is damaged.
  4. Remove the black plastic covers from all the captive screws on the module front panel.
  5. Touch any metal part of the chassis to discharge static electricity.
  6. Place the module edges into the module guides at the top and bottom of the chassis, as shown in the following figure. Slide the module into the slots until it is fully inserted. Slide the module to the rear of the chassis, making sure that the injector/ejector handle is pushed down.

  7. When you begin to feel resistance, push up on the injector/ejector handle to fully seat the module into the chassis frame. Secure the module front panel to the chassis using the module 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.
  8. Cover all empty slots using EMC filler panels or fill using slot blockers to maximize cooling air flow, depending on your application.
  9. Leave the chassis powered off until you have installed the PXIe-7890 or PXIe-7891 module.
