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).
3.7.7.4 Surge Immunity
The power supply shall be tested with the system for immunity, per EN 55024:1998, EN 61000-4-5:1995 and
ANSI C62.45: 1992.
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. Limits shall comply with those specified in the Intel Environmental
Standards Handbook.
3.7.8 Protection Circuits
Protection circuits inside the power supply shall cause only the power supply’s main outputs to shutdown. If
the power supply latches off due to a protection circuit tripping, an DC cycle OFF for 15sec and a PSON# cycle
HIGH for 1sec shall be able to reset the power supply.
