    4. Remove the filler panels.
    5. Disconnect all the cables from the PXI instrument.
    6. Remove the terminal block PXI instruments.
      1. Ensure that the devices and circuits connected to the terminal block are powered down and are no longer hazardous live.
      2. Loosen the mounting screw located at the top of the terminal block using the #2 Phillips screwdriver.
      3. Raise the terminal block latch release using a flathead screwdriver to disengage the latch.
      4. With the latch release raised, pull the terminal block away from the module.
      5. Store the terminal block in an antistatic protective bag.
    7. Remove the non-terminal block PXI instruments.

    9. Eject the PXI instrument from the chassis using the ejector handle.
    10. Slide the PXI instrument out of the chassis.
    11. Install the non-terminal block replacement PXI instruments.
      1. With the ejector handle engaged, slide the replacement PXI instrument into the appropriate chassis slot.
