Power-button-connector@Jetson TX2-board, rev C02

I have a C02-reference board with a Jetson TX2 that should be mounted in a chassis. However, I can’t find the connector for the power-button on the board, not even when I look at the manual.
Some-one knows where to find it?

It is ‘S4’ for power button, or pin 2 of J20, please check the C02 schematic in DLC.

Thanks, found it. Link to schematic for future references (and if some-one else has a similar question):
