Step 4: Deploy Additional Unleashed Member Access Points
Deploying additional Unleashed member APs is simply a matter of connecting them via Ethernet to the same Layer 2 network and providing power. They will discover the Unleashed Master and join automatically. No additional steps are necessary.
The second and any additional APs that join an Unleashed network will automatically assume the role of Unleashed "member AP." Thereafter, if the Master AP goes offline, one of the member APs will become the new Master and assume control of the Unleashed network.
