2.2.2.3 Susceptibility Requirements
The power supply meets the following electrical immunity requirements when connected to a
cage with an external EMI filter that meets the criteria defined in the SSI document EPS Power
Supply Specification.
Table 26. 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 degradationof
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.
2.2.2.3.1 Electrostatic Discharge Susceptibility
The power supply complies with the limits defined in EN 55024: 1998 using the IEC 61000-4-
2:1995 and the level 3 test standard and performance criteria B defined in Annex B of CISPR
24.
