Ex4300 cluster adding SPF card and add Ex3300 to the cluster

I have an ex4300 switch that is clustered with 5 ex4300 switches. I am adding EX-UM-4X4SFP card on the Primary and secondary of the ex4300 cluster then connect 3 of the ex3300 on a different floor.

1. How do I program the EX-UM-4X4SFP card to the Primary and secondary of the ex4300 on the cluster.

2. Then add the other 3 ex3300 switches to the SFP and cluster them to the ex4300.
