4 Power Subsystem

This section provides a high-level overview of the power management features and specification data for the

power supply options available for the Intel

Storage System JBOD2312S3SP. Specification variations are

identified for each supported power supply.

Although the Intel

Storage System JBOD2000S3SP ships with only one power supply, a second one can be

installed and 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

(Although this system cannot be loaded high enough to hit this mode). The 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. If this occurs, 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. If system

thermals exceed programmed limits, platform management will attempt to keep the system operational.

Thermal support is open loop based on ambient temp sensor on the front panel.

The only power supply option validated for the Intel

Storage System JBOD2312S3SP is the 460W AC PS.

The 750 W AC PS will fit and operate, but will not be validated in the JBOD or plan of record.

NOTE: The power cord is not included with the spare power supply and must be ordered separately. Please

refer to the Intel® Storage System JBOD2000S3 Product Family Configuration Guide for ordering information

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 PDB 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.
