Adding 2 extra drives to a ex4100

Hi I have an ex4100 with 2 drives in it on raid 1 and I have bought another two drives to go in the other 2 drive bays, I have inserted the drives but they don’t show in the dashboard and I have 2 blue lights on and 2 red lights on.
How do I format the new drives for use without affecting the original drives
