Hello NVIDIA Team,

I’m having some difficulties getting a device connected via the 1000BASE-T1 ports on the Spruce switch and I was looking to confirm that the following is correct to help debug and confirm our observations:

  1. Are all of the port roles for the 1000BASE-T1 connectors set as Master/Primary? This document says so but i wanted to confirm this is the case. We are using the base configuration as confirmed in Aurix. I am connected on pin 1 on J4.
  1. I am connecting a device that is a 1000BASE-T1 slave. This is set to have an IP address on that same network. This is the only device connected.

Pings all fail, I can see on the arp table that the IP address is present so i’m confident in the setup. I’ve also used a media converter setup as a master and 1000BASE-T1 and i can communicate to the device i am connecting. I’m confident that I am configuring the attached device correctly in this case.

Is there any mechanism to check the Port role to confirm if it is configured correctly? i understand that changing the port role may not be supported by the forum, but is checking the status possible?


We will review your questions and provide a response as soon as possible.

If an Nvidia-provided media converter is used, it can be used to identify the link status and Base-T1 role, if the link is established. To obtain this information, the media converter needs to be connected to a host via the USB port, without changing the network connections, and the device needs to be opened using minicom (which appears as /dev/ttyACM* on Linux machines). By decoding the output of the console, we can obtain the necessary information.

For example, if converter P3751 is used, the following output indicates that the Base-T1 on the converter is in 1G slave mode, indicating that the Spruce port it is connected to is in Base-T1 master mode.

Hello VickNV,

I do have an NVIDIA-provided Media converter and this can work as a viable solution for us. One last question, from the debug statement, how does this line change if it’s setup as a master? i.e. does the Link Status line change and what does it look like if it’s in master mode?

thanks for all of your help in working to find a solution to this!

The Link Status line will show “1Gm”.
