System Power
This chapter provides a high level overview of the features and functions related to system power.
3.1
Power Supply Configurations
The server system can have up to two power supply modules installed and can support the following power
supply configurations: 1+0 (single power supply), 1+1 redundant power, and 2+0 combined power (non-
redundant). 1+1 redundant power and 2+0 combined power configurations are automatically configured
depending on the total power draw of the system. If the total system power draw exceeds the power capacity
of a single power supply module, then power from the second power supply module is utilized. Should this
occur, power redundancy is lost. In a 2+0 power configuration, total power available maybe less than twice
the rated power of the installed power supply modules due to the amount of heat produced with both
supplies providing peak power. Should system thermal levels exceed programmed limits, platform
management attempts to keep the system operational. For details, see section 3.6 and chapter 4.
Caution
: Installing two power supply units with different wattage ratings in a system is not supported. Doing
so does not provide power supply redundancy and results in multiple errors being logged by the system.
The power supplies are modular, allowing for tool-less insertion and extraction from a bay in the back of the
chassis. When inserted, the card edge connector of the power supply mates blindly to a matching slot
connector on the server board.

In the event of a power supply failure, redundant 1+1 power supply configurations have support for hot-
swap extraction and insertion. The AC input is auto-ranging and power factor corrected.
