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

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.
