Routerboard SXT-LTE6 mode switch what is for??

Hi.
I have found hidden behind the SIM of my SXT-LTE6 there is a switch tagged “MODE” same as “RESET” one seen from the plastic door.
Does anyone knows what’s for?
Thank you,

It could be used for running some scripts in RouterOS. You could set it in “System-RouterBOARD-Mode Button” menu. (RESET button as well, as you could notice in the RouterBOARD menu)

Thanks Pal
