Replacing a Cooling Fan 1 Align the fan module so that the side with the power cable faces toward the back of the system. 2 Slide the fan module into the fan assembly until the fan is fully seated. See Figure 3-15 and Figure 3-16. 3 Connect the fan's power cable to the power connector on the system board. 4 Route the power cable through the guides on the chassis. NOTE: For twelve-hard-drive systems, first replace the internal hard-drive carrier and bay. See "Installing an Internal Hard Drive Bay" on page 101. 5 Replace the cooling shroud. See "Installing the Cooling Shroud" on page 91. 6 Close the system. See "Closing the System" on page 89. 7 Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals. Power Supplies Your system supports the following power supply modules: • Systems with cabled hard drives support 480 W (non-redundant power supply) • Systems with hot-swappable hard drives support 750 W/1100 W (redundant power supply) 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 in a redundant configuration. See "Installing the Power Supply Blank" on page 112".
