The PXIe-8370 also has a vertical column of 16 LEDs on the module back panel near the front
connector, as shown in the following figure. These LEDs provide additional information to the
backplane about the link status of the PCI Express lanes on the module. Each group of four
LEDs corresponds to one of the four PCI Express links to the backplane.

Note
If you are using a chassis (such as the PXIe-1062) that directly links the PXI
Express board, the LEDs to that slot do not illuminate until you have installed and
linked a PXI Express module.
If you are using the PXIe-1062 chassis, notice that the last group of LEDs has an
LED (PORT 3) illuminated even if no boards are populated in the slots. Because the
PXIe-1062 uses the last link for a PCI Express to PCI bridge for PXI
communication, this link always should be active. Different chassis topologies give
different default behaviors. Contact your chassis' manufacturer for more information
about your chassis' topology.
Software Installation and Configuration
Installation
MXI-Express x4 is based on PCI Express technology, using PCI Express switches and/or
bridges to enable control of a PXI Express chassis from a PC or another PXI Express chassis
with an available PCI Express or PXI Express slot. This technology will be recognized as a
collection of PCI-to-PCI bridges to the operating system, and should automatically have
CompactPCI Express level support without any additional software.
Note
For full PXI/PXI Express functionality such as chassis and controller
identification, trigger routing, and slot detection, install the PXI Platform Services
