This was something in the early days of Polisy that got added to IoX. I'm not sure if it does anything now, but just hasn't been removed. It's not something I'd push if there's no discussion about it in the forums. Here's a post from @Michel Kohanim about this button.

"Reboot" is supposed to reboot the device. Sometimes it works as expected, but sometimes it hangs and doesn't perform a full system reboot and power cycle is needed.

"Restart IoX" should just restart the IoX system. It's not used as much as it once was when it was "Restart ISY" on the (old) ISY994 devices. It's probably useful if you're working with support and trying to troubleshoot IoX issues and just want to restart the IoX system, but usually isn't something that many often suggest here. 

 

Also, the "Update BIOS" is another button that showed up early in Polisy time that rarely got mentioned and doubtful that it should remain and certainly wouldn't push it unless instructed to do so by support.

A reboot and a restart sounds like the same thing.  maybe a reboot is like a power cycle and a restart just stops all of the software and restarts it?

UD should clarify, but to me it sounds like Reboot is full OS based and Restart IOX is limited to the IOX service itself.

Which makes me wonder what about a UDX service restart?

Exactly, but I think that’s what has caused issues….a reboot doesn’t actually power cycle the device, but more or less stops all services and starts them again. But I’m no programmer and just hypothesizing what is being attempted/done. That’s why when some updates wouldn’t complete a full power cycle was necessary to get the systems started in the correct order again. 
 

Reboot basically tells the device to start up fresh. From comments elsewhere it’s basically telling the device to start with the UDX then ISY then PG3 services. I’m sure it’s way more involved, but that’s my simple way of thinking about it.

Restart IoX just focuses on that service running on the device. When it was simply an “ISY” device (be it 26, 99, or 994) it restarted the device, but now that the Polisy and eisy have multiple services running then the device needs a “reboot” function and ISY/IoX has a “restart” option. Just like PG3 used to have on the web portion to restart the Polyglot system, but that was removed.

To me the reboot is restarting the UDX. Because ISY and Polyglot rely on UDX so much if that gets restarted then the ISY and Polyglot services should be restarted…thus “reboot”. I wouldn’t expect that there would be a simple way to ONLY restart the UDX system. The other services are dependent on it too much to have that core component restart without impacting the other services.
