We are using the auto power on for Nvidia Xavier jetson. Auto powering works great. But to shut down, we have to connect to the machine ssh and to run shutdown command. We have a complex setup of 6 Xaviers. We are looking for a way to send a hardware trigger to start a controlled shutdown instead — i.e., without the need to connect remotely to the Jetsons.
Hey, Thanks for the answer but unfortunately accessing the power button is not an option. Is it possible to simulate pressing by shortcutting some jumper on the board?
For the AGX Xavier, I noticed that if you press the power button shortly in on-state, the system will shutdown gracefully most of the time (maybe, once I needed to press for 10s, but can’t reproduce).
AFAIK, button press is identical to connecting pins 1 (gnd) and 4 (power button) on the automation header of the dev kit, which means, automation is easy.
The manual states “If held for >10 seconds, will shut down the system”. Can you tell me if that means shutdown gracefully and how that is implemented? Why do I get a shutdown within 6s after a very short press?

Hi @alonmo4zt, you can use an Out-Of-Band control module which can connect to power switch pins of your Xavier platform (it’s on J508 pins). This Out-Of-Band control module can be accessed from Internet actually, means you can conduct each power cycling (on/off/reset) remotely.
Hi @alonmo4zt,
Were you able to figure out how to power off through hardware signal?
I am trying to get the Jetson devices (NX/AGX) to power off gracefully after power interruption. And also need to power it up afterwards on demand.
