3.6.1 Power Supply Upgrade
The basic system comes with only one 400-watt power supply module
installed. The power subsystem design allows you to upgrade the
basic power configuration by adding one or two more power supply
modules.
Make sure to unplug the power cable from
the wall socket before you install or remove a
power supply module.
Installing a Power Supply
Follow these steps to install a power supply module:
