Power Supplies

Your system supports two 750 W redundant power supply modules.

NOTE: The maximum output power (shown in watts) is listed on the power supply label.

If two power supplies are installed, the second power supply provides hot-swappable, power redundancy. In redundant mode, the system distributes the power load across both power supplies to maximize efficiency. When a power supply is removed with the system powered on, the full power load is picked up by the remaining power supply.

CAUTION: To ensure proper system cooling, the power supply blank must

be installed in the PS2 bay. See "Installing the Power Supply Blank" on page 80".
