MS Network access protection server load balance

I have taken over the administration of AD and it includes MS Network Protection server. I see two NPS servers and do not see proxy setting on it for RADIUS. Is switch is taking care of load balance?
I wonder how they load balance, I would appreciate your help on this?

normally you have a fail-over if you configure more than one radius server (NPS) at the switch.
The second server is only used if the first is unreachable.  
You can loadbalance by changing the server-order from switch to switch.
