• Install 800W or 1600W power supplies into power supply bays 1—4.
• For redundancy, connect AC power from one power circuit to power supplies 1 and 2 (orange), and then
connect power supplies 3 and 4 (blue) to a separate AC circuit.
For power supply bay identification, see Rear panel components on page 19.
