Power supplies The Netfinity server is shipped with a 350-watt power supply that provides redundant power through the use of two internal power modules. If the server load does not exceed 175 watts, and a problem occurs with one of the power modules in the power supply, the other module takes over the load. For power loads above 175 watts, you can install a second, optional, power supply to provide redundant power for the server. The second power supply contains one 175-watt power module. With the optional second power supply installed, if a problem occurs with any of the power modules, the remaining two power modules supply the needed 350 watts of power. The LEDs on the back of each power supply indicate the status of each of the power modules. If an LED is not on, there is a problem with the power supply module, and the power supply must be replaced. To install or remove the optional second power supply, see the instructions that come with the option. To replace the 350-watt power supply, see "Power supply removal" on page 133. If you want to install or remove any other options, do so now. Otherwise, go to "Completing the installation" on page 77. 132 Netfinity Server HMM

Power supplies
The Netfinity server is shipped with a 350-watt power
supply that provides redundant power through the use of
two internal power modules.
If the server load does not
exceed 175 watts, and a problem occurs with one of the
power modules in the power supply, the other module
takes over the load.
For power loads above 175 watts,
you can install a second, optional, power supply to provide
redundant power for the server. The second power supply
contains one 175-watt power module.
With the optional
second power supply installed, if a problem occurs with
any of the power modules, the remaining two power
modules supply the needed 350 watts of power.
The LEDs on the back of each power supply indicate the
status of each of the power modules.
If an LED is not on,
there is a problem with the power supply module, and the
power supply must be replaced.
±
To install or remove the optional second power
supply, see the instructions that come with the option.
±
To replace the 350-watt power supply, see “Power
supply removal” on page
133.
If you want to install or remove any other options, do so
now.
Otherwise, go to “Completing the installation” on
page 77.
