Note
The slot number printed on the glyph may vary from chassis to chassis.
The circle inside of the square indicates that the slot may also be used as a PXI Express
peripheral slot.
3.
Remove the filler panel for the PXI slot you located in step 2.
4.
Ground yourself using a grounding strap or by holding a grounded
object. Follow the ESD protection precautions described in the
section of Chapter 1,
5.
Remove any packing material from the front panel screws and
backplane connectors.
6.
Insert the NI PXIe-6672 into the PXI Express slot. Use the
injector/ejector handle to fully insert the module into the chassis.
7.
Screw the front panel of the device to the front panel mounting rail of
the chassis.
8.
Visually verify the installation. Make sure the module is not touching
other modules or components and is fully inserted into the slot.
9.
Plug in and power on the chassis.
The NI PXIe-6672 is now installed.
Configuring the Module
The NI PXIe-6672 is completely software configurable. The system
software automatically allocates all module resources.
The two LEDs on the front panel provide information about module status.
The front panel description sections of Chapter 3,
,
describe the LEDs in greater detail.
