or out of regulation conditions, but shall not damage the power supply. The power supply should recover and
meet all turn on requirements for DC dropouts that last longer than 0.2ms. The power supply must meet the
DC dropout requirement over rated DC voltages and output loading conditions.
3.7.6 DC Line Surge Voltages (Line Transients)
The Power Supply should demonstrate tolerance for transients in the input DC power line caused by switching
or lightning. The power supply shall be primarily tested and must be compliant with the requirements of
EN61000-4-5: “Electrical Fast transients / Burst Requirements and Surge Immunity Requirements” for surge
withstand capability. The test voltage surge levels are to be: 500Vpk for each Line to Primary Earth Ground
test (none required between the L1 and L2). The exact description can be found in Intel Environmental
Standards Handbook 2001.

3.7.7 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.
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.
3.7.7.1 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. Limits shall comply with those specified
in the Intel Environmental Standards Handbook.
3.7.7.2 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. . Limits shall comply with those specified
in the Intel Environmental Standards Handbook.
3.7.7.3 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. . Limits shall comply with those specified in the Intel
Environmental Standards Handbook. Additionally, must also comply with field strength requirements specified in GR 1089
(10V/meter).
