The rear switches are hard power switches and that is not what we are discussion here.
The AT4000/AT6000 when initially produced would power on with the trigger after powering on. However, when the power was removed using the rear power switches or loss of power, they did not response to the trigger until the front touch capacitive power button was engaged.
Here is my 2018 article on the AT6000s:

The article included this editorial note:
At the time, I also tested an AT4000 which had the same trigger issue.
In 2019, I wrote this article comparing the AT4002 and AT522NC amplifiers:
https://www.audioholics.com/amplifier-reviews/ati-at4002
It included this editorial note on the Auto-Off function that had to be disabled:
The AT4002 supplied for this review, did not have the trigger issue. It triggered on after a hard power cycle.
If you have an issue with triggers not working on an AT6000/AT4000 amp, I recommend contacting ATI to have it repaired.
Them's the facts.

EDIITORIAL NOTE ON TRIGGERING
When I first received the AT6000’s the trigger functionality required pressing the power button to complete the power cycle. If the power ever went out the amps would not turn on until the power button was pressed. This is not “family friendly.” Updated control boards unconditionally power-on from the trigger, eliminating instances of pops on power up, and also improving the soft power-up process.
At the time, I also tested an AT4000 which had the same trigger issue.

EDIITORIAL NOTE ON AT500NC Auto-Power Off
My AT522NC auto-power off features was not functioning properly. Whether manually or trigger power-on, the amp powers off after 10 minutes. Apparently, an EU feature gone awry. Thankfully, ATI has a procedure that involves pressing the power button while plugging-in the power cable that disables the inactivity power-off function. Once disabled, the manual and trigger power-on works properly.
The AT4002 supplied for this review, did not have the trigger issue. It triggered on after a hard power cycle.
