Technical Product Specification
Intel® Server System R2000IP Product Family TPS Power Subsystem
Revision 1.1
23
The pass criteria include: No unsafe operation is allowed under any condition; All power supply
output voltage levels to stay within proper spec levels; No change in operating state or loss of
data during and after the test profile; No component damage under any condition.
The power supply shall comply with the limits defined in EN55024: 1998 using the IEC 61000-4-
5:1995 test standard and performance criteria B defined in Annex B of CISPR 24.
3.5.20 AC Line Leakage Current
The maximum leakage current to ground for each power supply shall be not more than 1.75mA
when tested at 240VAC.
3.6 DC Output Requirement
3.6.1 Connector
The power supply module shall use the card edge for output power to the power distribution
board with the mating connector of (Molex 459840005) and AC input power to the module.
3.6.2 Grounding
The ground of the pins of the power supply output connector provides the power return path.
The output connector ground pins shall be connected to safety ground (power supply
enclosure). This grounding should be well designed to ensure passing the max allowed
Common Mode Noise levels, see section 7.11.
3.6.3 Remote Sense
The power supply module uses remote sense (12VRS) to regulate out drops in the PDB
connectors for the +12V output. The power supply has +12VRS- and +12VRS+ for remote
sense to regulate out voltage drops for its +12V output voltage. The remote sense must be able
to regulate out a minimum of 200mV drop.
3.6.4 Output Power/Currents
These are the power requirements for the power supply module.

3.6.5 Voltage Regulation
The power supply output voltages must stay within the following voltage limits when operating at
steady state and dynamic loading conditions. These limits include the peak-peak ripple/noise.
