Power Supplies
Depending on your configuration, your system supports up to two hot-
pluggable redundant power supplies rated at 675 W, or a single
non-redundant power supply rated at 650 W.
If your system has redundant power supplies, see "Removing a Redundant
Power Supply" on page76 or "Installing a Redundant Power Supply" on
page77. If your system has a non-redundant power supply see "Removing a
Non-redundant Power Supply" on page78 or "Installing a Non-redundant
Power Supply" on page81.
If two redundant power supplies are installed, the second power supply
provides 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.
