Keysight PXI/AXIe Chassis Troubleshooting Guide

Guidelines to Diagnose and Resolve Communication Problems
Setup Applications with Recommended and Supported Configurations
There are many configurations you can create to setup a proper PXIe or AXIe
system. Refer to the Interface Modules and Adapters for PXIe and AXIe Systems
https://literature.cdn.keysight.com/litweb/pdf/5992-0377EN.pdf
for other examples of recommended and supported configurations. You can also
use the Multi-Chassis Designer Tool (
www.keysight.com/find/pxie-multichassis
)
to check if your configuration is supported.
Power-up the Chassis First
Always power up all chassis before booting the PC if you are using an external
PC. An embedded PC will power-up correctly if using a single chassis, but slave
chassis must be powered-up first. If you are connecting multiple chassis
together, consider using the multi-chassis power sequencing capability built into
many of Keysight’s chassis.
Ensure LEDs are Lit Correctly on System Module
If you are using the M902xA system modules in the PXIe system with PC
configuration, ensure the status LEDs are lit and are the correct color for your
given configuration. The status LEDs tell you the status of the module, the link
connection, and the backplane connection. There are also a series of LEDs across
the top and bottom of the system modules indicating power and configuration.
Refer to the PXIe System Modules and Cable Interface Installation Guide

)
for details of how to diagnose connection issues with these LEDs.
Lower Transfer Rate Settings to Ensure Reliability
Sometimes a device cannot correctly follow the PCIe training protocol and the
link fails to connect reliably. As a workaround or diagnostics debug step, you can
use the DIP switches on the system modules to lower the maximum negotiated
PCIe speed to Gen1. This lower speed may allow your device to function reliably.
Refer to the PXIe System Modules and Cable Interface Installation Guide for
instructions on setting the DIP switches.
