Hello Mohamed.
In a redundant configuration, the first Power Supply is connected to the slot 1 in the backplane and the second PS module to the slot 2. So first of all check out that both PS are working fine individually and then insert them like in the picture below.
No further configuration would be needed. I hope this helps you.
