Once I have setup schedules in all my HS switches, I assume that they are recorded in the switch itself, and can live their life as

a standard programmable switch 

I want to "disconnect" them from the lan? 

I can do that by removing their MAC from approved devices, but they keep trying to reconnect and blinking .

can this be disabled (with re-enability)?   

using for  restar&reset switches

(BTW I have not figured yet the difference between the two)

Thanks
