When wiring repeaters using the Ethernet connection, I imagine it's still best practice for the repeaters to be within 60ft of one another, but is it needed at that point since it's not over RF? Can they essentially be "on their own 30ft bubble islands" for devices? Or do the repeaters convert to an RF link in a failover-scenario if, say one repeater has their Ethernet connection fail (let's say the switchport died).
