RBR750/RBS750 Reboot Behavior

I installed the Orbi RBK753S, which consists of the RBR750 router and (2) RBS750 satellites.  So far, it seems to be working well.  I do have them set up as AP, if that makes a difference.  My question is, when I click on the Reboot button on the web gui (within the Router Information section), does that strictly perform a reboot on the RBR750, or does it also reboot the satellites?
