Does Zedbox orin have indicators to capture the kernel is unloaded?

Hello,
We are currently using the Zedbox Orin NX in a mobile robot platform. In our application, minimizing power consumption is critical, so we would like to shut off the 12V power supply to the Zedbox when it is no longer needed.

To do this safely, we need a reliable way to detect when it is safe to turn off the 12V power after issuing a shutdown command. The challenge is that the Zedbox is only connected to the main robot system via:

  • 12V power
  • Ethernet (non-PoE)
  • GMSL (2 channels)

We do not have access to GPIOs or other signals that might indicate shutdown completion directly. Monitoring network traffic, using ping responses, or waiting a fixed time after issuing shutdown does not seem robust or safe enough.

Is there a recommended or supported method to detect — from an external controller — when the Zedbox has fully shut down and it is safe to cut its 12V supply?

You could monitor the power line of one of the USB ports.
It should be turned off (I must double-check this for confirmation) when the shutdown is completed.

Thanks for your information.
Can I have an update if I can use USB 5V power on that purpose?

The USB 5V power stays active after a software shutdown; hence, it’s not useful for your task.

Thanks for your information.

Then do we have other ways for the system to capture when is safe(or saver) to power down? For instance, using network response, etcs…
