Technical Product Specification

Power Subsystem Intel® Server System R2000IP Product Family TPS
22 Revision 1.1
 The surge-withstand test must not produce damage to the power supply.
The supply must meet surge-withstand test conditions under maximum and minimum DC-output
load conditions.
3.5.14 AC Line Isolation Requirements
The power supply shall meet all safety agency requirements for dielectric strength. Additionally,
we can provide written confirmation of dielectric withstand test which includes: voltage level,
duration of test and identification detailing how each power supply is marked to indicate
dielectric withstand test had been completed successfully. Transformers’ isolation between
primary and secondary windings must comply with the 3000Vac (4242Vdc) dielectric strength
criteria. If the working voltage between primary and secondary dictates a higher dielectric
strength test voltage the highest test voltage should be used. In addition the insulation system
must comply with reinforced insulation per safety standard IEC 950. Separation between the
primary and secondary circuits, and primary to ground circuits, must comply with the IEC 950
spacing requirements.
3.5.15 Susceptibility Requirements
The power supply shall meet the following electrical immunity requirements when connected to
a cage with an external EMI filter which meets the criteria defined in the SSI document EPS
Power Supply Specification. For further information on Intel standards please request a copy of
the Intel
®
Environmental Standards Handbook.
Table 15. Performance Criteria
Level
Description
A
The apparatus shall continue to operate as intended. No degradation of performance.
B
The apparatus shall continue to operate as intended. No degradation of performance beyond spec limits.
C
Temporary loss of function is allowed provided the function is self-recoverable or can be restored by the
operation of the controls.
3.5.16 Electrostatic Discharge Susceptibility
The power supply shall comply with the limits defined in EN 55024:1998 using the IEC 61000-4-
2:1995 test standard and performance criteria B defined in Annex B of CISPR 24.
3.5.17 Fast Transient/Burst
The power supply shall comply with the limits defined in EN55024: 1998 using the IEC 61000-4-
4:1995 test standard and performance criteria B defined in Annex B of CISPR 24.
3.5.18 Radiated Immunity
The power supply shall comply with the limits defined in EN55024: 1998 using the IEC 61000-4-
3:1995 test standard and performance criteria A defined in Annex B of CISPR 24.
3.5.19 Surge Immunity
The power supply shall be tested with the system for immunity to AC Ring wave and AC
Unidirectional wave, both up to 2kV, per EN 55024:1998, EN 61000-4-5:1995 and ANSI C62.45:
1992.
