How do I change the PXIe-8240 from 40G rate to 10G rate?

How do I change the PXIe-8240 from 40G rate to 10G rate?

I am using a PXIe-8240 in a PXIe-1094 chassis using WINDOWS.

Using LabVIEW, I can send UDP packets from one port (Eth0) to the other port (Eth1) through a direct connect OM3 fiber cable and the LINK SPEED LED on the front panel is GREEN indicating the speed is 40G. The WINDOWS ethernet controller settings for ports Eth0 and Eth1 also indicates it is running at 40G.

Note: The PXe-8240 literature indicates the LINK SPEED LED is the following (green = 40 Gbps; yellow = 10 Gbps)

How do I change the rate on the PXIe-8240 from 40G to 10G?

My problem is when I connect the PXIe-8240 to my UUT, there is no link light. The literature indicates the rate should auto-negotiate, but it does not. The WINDOWS ethernet controller settings indicates the PXIe-8240 is at 40G and the Link LED never turns on.

My UUT is QSFP+ running at 10G.

When I connect the OM3 fiber cable directly from the PXIe-8240 port (either the ETH0 or ETH1) to the UUT, I do not get a link light.

The WINDOWS ethernet configurations settings indicate the PXIe-8240 is set at 40G Full Duplex, not at 10G full duplex.

The WINDOWS ethernet configurations setting for the rate is grayed out, so I cannot change to speed to 10G Full Duplex. It stays at 40G. 

How do I change the PXIe-8240 rate to 10G if the WINDOWS ethernet configurations setting is grayed out and not selectable?

Thank you.

PXIe-8240 uses an Intel XL710 40Gb Ethernet controller. You can use Intel® QSFP+ Configuration Utility to change the configuration. See QUC.book (intel.com)

Thanks for the link to the QSFP+ Configuration Utility (QSU). I went to the intel website to download the QCU. 

https://www.intel.com/content/www/us/en/download/18640/intel-qsfp-configuration-utility-qcu-disconti... 

The website indicated the QCU is discontinued and replaced by EPCT. 

"Intel® QSFP+ Configuration Utility (QCU) - Discontinued and Replaced by Ethernet Port Configuration Tool (EPCT)" 

The link to download EPCT is

Thanks for pointing me in the right direction. 

I'll download EPCT and configure the PXIe-8240 using the EPCT.

We are having trouble installing the PXIe-8240 driver. The driver name is "pxie8240EthDriver.msi" that I downloaded from the NI website. 

This driver was previously installed, but we were having trouble with the module so we uninstalled this driver and hoping to reinstall the driver. Now the "pxie8240EthDriver.msi" installer is not working. 

When we run the  "pxie8240EthDriver.msi" installer, the driver does not get installed and it says "The installer ended prematurely". We have already made sure that the Platform Services is properly installed. The Platform Services we are using is version 20. 

How do I install the driver if the installer ends prematurely and does not load the PXIe-8240 driver? 

Is there an  "pxie8240EthDriver.msi" uninstaller? 

Thank you
