Power Subsystem

This chapter provides 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.
The server system can have upto 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 2
redundancy is lost. In a 2+0 power configuration, total power available maybe less then 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 programmed limits, platform management will attempt to keep the
system operational. See Closed Loop System Throttling (CLST) later in this chapter, and Chapter 4 Thermal
Management, for details.
There are three power supply options available for this server product: 460W AC, 750W AC, 750W DC.
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.

Mechanical Overview

The physical size of the power supply enclosure is 39/40mm x 74mm x 185mm. The power supply contains a
single 40mm fan. The power supply has a card edge output that interfaces with a 2x25 card edge connector in
the system.
