This is the side of the h724 power supply which faces the cards. The fans cool both the power supply and the cards in the backplane. The part at the top left is the terminal interlock. It will shut off power if the unit gets too hot until pushed to reset.
The connector next to the one with the cable provides low voltage AC to option cards such at the real time clock. The other two connectors are the output power connectors.
