Installing power supplies
Use this information for an overview of the type of power supplies that the server supports and information
about installation rules and population sequence.
The server supports 900-watt ac power supplies, 1400-watt ac power supplies, and 750-watt -48 volt dc
power supplies. For more information about the supported power supplies and instructions on how to install
the power supplies, see “Installing a 1400-watt or 900-watt hot-swap power supply” on page 107 and
“Installing a 750-watt -48 volt to -60 volt dc power supply” on page 102.
Note:
The information and instructions in this documentation apply to both the 4-socket and the 8-socket
server.
The following list describes the types of power supplies that the server supports and other information that
you must consider when you install power supplies:
• The server default power supply configuration setting, when shipped from the factory, is non-redundant
mode with throttling enabled for both ac and dc power supply models. If you want to change the mode to
redundancy mode, you must use IMM2 web interface to set and change the power supply Power Policy
and System Power Configurations options settings. You can set and change the policies and
configurations using the IMM2 web interface, CIM, or the Advanced Settings Utility. You cannot set or
change the Power Policy or System Power Configurations setting using the UEFI Setup utility. For more
information, see “Setting power supply power policy and system power configurations” on page 137.
• If you are using two power input feeds, connect power supplies 1 and 3 to input feed A and power
supplies 2 and 4 to input feed B.
• You cannot mix ac and dc power supplies in the same server.
