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.
