Installing System Components

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 and Figure 3-8.

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:

If applicable, first replace the internal hard-drive carrier and bay.

5 Replace the cooling shroud. See "Installing the Cooling Shroud" on

page 73.

6 Close the system. See "Closing the System" on page 71.
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:

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 83".

NOTE:

If only one power supply is installed, it must be installed in the PS1 power

supply bay.
