Obtaining images from multiple cameras connected to IGX Orin Developer Kit

Hi, I’ve read

and didn’t find instruction on my current situation:

My colleague gave me a switch, I connected it to right QSFP28 port, then connected IMX274 camera, and two third party camaras to the switch.
I wish to run three player program (in Python) simultaneously, and got image from those three cameras on three different Holoviz window. All of them works well when connected to QSFP28 port directly, no matter monocular or binocular. Is it possible to do so on IGX?
IMX274 connected to QSFP28 directly, MAC address is 00:50:c2:58:c2:db
the other two connected to QSFP28 directly, MAC address are both ff:ff:ff:ff:ff:ff
Switch connected to QSFP28 without any camera connected to switch, press arp -a, no MAC address found, on the terminal it said (192.168.0.2) at on enP5p3s0f0np0
Only IMX274 worked when only one camera connected to switch, any idea why this happened?
For the other two (if only one of them connected to switch), Holoviz appeared without image, ping 192.168.0.2 didn’t work, “Holoviz - 192.168.0.2” is not responding; error: XDG_RUNTIME_DIR not set in the environment. appeared on terminal (in docker).
I don’t think it’s possible to run 3 python programs simultaneously(I used “&&”, but they ran one by one, as I crossed Holoviz window).
What should I do to successfully got image from the other two cameras when they are connected to switch, and the switch connected to IGX?

Hi,
By default IGX developer kit supports HDMI input. Could you please share more information about the switch(brand and ID) and how it is connected to developer kit? Would like to see which interface is used and check whether it is supported.

It’s TRENDnet 5-Port 10G Switch. Model: TEG-S750 /A.
We also tried to run two IMX274 (another one has MAC address 00:50:c2:58:c0:df), only one of them work. If we unplug the working one and run script again, the other work.

We have 2 Lattice boards, with a IMX274 on, both are connected to switch.
