Make sure the injector/ejector handle is in its downward position. Align the NI PXIe-8840 
with the card guides on the top and bottom of the system controller slot.

Caution

Do 

not

 raise the injector/ejector handle as you insert the NI PXIe-8840. 

The module will not insert properly unless the handle is in its downward position so 
that it does not interfere with the injector rail on the chassis.

6.

Hold the handle as you slowly slide the module into the chassis until the handle catches on 
the injector/ejector rail.

7.

Raise the injector/ejector handle until the module firmly seats into the backplane receptacle 
connectors. The front panel of the NI PXIe-8840 should be even with the front panel of the 
chassis.

8.

Tighten the four bracket-retaining screws on the top and bottom of the front panel to secure 
the NI PXIe-8840 to the chassis.

Check the installation.

10. Connect the keyboard and mouse to the appropriate connectors. If you are using a PS/2

connector. National Instruments offers a Y-splitter adapter cable, part number 778713-02, 
available through the online catalog at

the DisplayPort connector.
