 These input transients must not cause any out-of-regulation conditions, such as
overshoot and undershoot, nor must it cause any nuisance trips of any of the power
supply protection circuits.
 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.
3.2.8 Hot Plug
Power supply shall be designed to allow connection into and removal from the system without
removing power to the system. During any phase of insertion, start-up, shutdown, or removal,
the power supply shall not cause any other like modules in the system to deviate outside of their
specifications. When AC power is applied, the auxiliary supply shall turn on providing bias
power internal to the supply and the 5VSB standby output.
3.2.9 Susceptability 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 customer standards please request a
copy of the customer Environmental Standards Handbook.
Table 16. 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.
3.2.10 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.
3.2.11 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.
3.2.12 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.
3.2.13 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.
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.
