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".
For twelve–hard-drive systems, first replace the internal hard-drive
