Thank you for the follow up. X550-T2 is capable of NBASE-T (2.5 GbE \ 5 GbE) available only in Linux system with driver version 4.3.9. Please refer to the driver link below: https://sourceforge.net/projects/e1000/files/ixgbe%20stable/4.3.9/ https://sourceforge.net/projects/e1000/files/ixgbe%20stable/4.3.9/
We will further check about the Windows driver.
The windows drivers do support NBASE-T but only with auto-negotiation, you cannot set it manually. In case you already have the infrastructure (the switch that supports 2.5Gbe), please try the latest X550-T2 Windows driver available at our website
you stated that I must have a 2.5Gbe switch to test this capability.
1.As I have X500-T2 I have 2 Ehternet slots, is it possible to form a loopback to the same computer using the windows10 driver?
2. Is it possible to connect to computers using X500-T2 to perform 2.5Gbe connection?
Further checking, this is not supported to connect X550-T2 to test the 2.5Gb speed without a switch. The speed can only be setup to 2.5 Gbps if the hardware (or the linking partner) auto-negotiation allows it.Hope this information clarified.
Please clarify your answer.
-If I install X550-T2 cards on two computers, in a point-to-point connection, it seems that the hardware does support 2.5GbE as the card supports it.
1. If I'm using Windows is it possible to create a 2.5GbE link between 2 computers in via the point-to-point connection?
2. If I'm using Linux is it possible to create a 2.5GbE link between 2 computers in via the point-to-point connection?
I don't have a 2.5GbE switch in my system...I bought X550-T2 to get this kind of connection between 2 PCs.
If you have support via telephone number \ EMAIL in Israel, I'd appreciate if you can post it here.
Thank you for the reply. Are you saying you already tried to install two X550-T2 in back to back connection via an RJ45 cable and getting 2.5Gbps? What is the operating system used?
As mentioned you need to use a switch to attain 2.5 Gbps, Windows drivers do support NBASE-T but only with auto-negotiation. Auto-negotiation mode means it will negotiate with the speed of the linking partner, e.g. if your switch is configured to run at 2.5 Gbps then the X550-T2 connects to the switch will run at 2.5 Gbps adapting the switch speed. However, if you connect both X550-T2 in back to back connection mode, it is unknown what is the current speed configured in both X550-T2 in auto-negotiation mode, this depends on the linking partner.
