3. Power Sub-System
This chapter will provide a high level overview of the power management features and
specification data for the power supply options available for this server product. Specification
variations will be identified for each supported power supply. There are three power supply
options available in Intel
®
Server System R1000JP Family: 450W AC, 450W DC, and 750W AC.
The server system supports redundant 450W AC power supply and redundant 450W DC power
supply. The server system which integrates the 750W AC power supply is a single power
supply system.
The redudant power supply platform can have up to two power supply modules installed,
supporting 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 will be utilized. Should this
occur, power redundancy is lost. In a 2+0 power configuration, total power available may be
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 thermals exceed the
programmed limits, platform management will attempt to keep the system operational. See
Closed Loop System Throttling (CLST) later in this chapter, and Chapter 4 for details.
In the event of a power supply failure, redundant 1+1 power supply configurations (for 450W AC
and 450W DC platforms) have support for hot-swap extraction and insertion.
3.1 450W AC Power Supply and Power Distribution Board
The 450W AC power supply with two outputs: +12V DC and +5V Standby. There is one Power
Distribution Board (PDB) for 450W AC 1+1 redundant power supply. The PDB is designed to
plug directly to the output connector of the power supply and it contains two DC/DC power
converters to produce other required voltages: +3.3V and +5V. The PDB is integrated in the
power supply cage.
3.1.1 Mechnical Overview
The following drawing is the cage which integrates the power supply units and the PDB.
