Power Subsystem
This chapter provides a high-level overview of the power management features and
specification data for the power supply options available for Intel
®
Storage Server System JBOD
2000 Family. Specification variations are identified for each supported power supply.
Although the Intel
®
Storage System JBOD2000 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 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. 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 Server 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 Spares, Parts List and 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.
