Set Up Your MXI-Express x4 System
The NI PXIe-8370 also has a vertical column of 16 LEDs on the back panel
of the card near the front connector, as shown in Figure 5. These LEDs
provide additional information about the link status of the PCI Express
lanes on the module to the backplane. Each group of four LEDs
corresponds to one of the four PCI Express links to the backplane.

Notes
If you are using a chassis (such as the NI PXIe-1062) that directly links the
PXI Express board, the LEDs to that slot will not illuminate until you have a PXI Express
board installed and linked.
If you are using the NI PXIe-1062 chassis, you will notice that the last group of LEDs has
an LED (PORT 3) illuminated even if no boards are populated in the slots. Since the
NI PXIe-1062 uses the last link for a PCI Express to PCI bridge for PXI communication,
this link should always be active. Different chassis topologies will give different default
behaviors. Contact your chassis’ manufacturer for more information on your chassis’
topology.
