Server System R1000EP Product Family TPS
20 Intel Order Number G67599-003 Revision 2.0
3.6.5 AC Line 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. Power supply shall operate normally without any
component damage under any condition.
BI-WAVE 12Ω±2.0kV (Common mode)
2Ω±1.0kV (Differential mode)
RING-WAVE 500A±2.0kV (Common mode)
500A±1.0kV (Differential mode)
3.6.6 AC Inrush
The peak inrush current shall be less than 55A peak at 115VAC input and 230VAC input, Cold
start and 25°C.
3.6.7 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.
Table 11. 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.
3.6.8 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.
AIR DISCHARGE ±8kV
CONTACT DISCHARGE ±4kV
3.6.9 Protection Circuits
If the power supply latches off due to a protection circuit tripping, an AC cycle OFF for 15sec
min (with +5VSB/0.1A) and a PSON
#
cycle HIGH for 1sec shall be able to reset the
power supply.
3.6.10 Over-current Protection (OCP)
Each output shall have individual OCP protection circuits. The PSU shall shutdown and latch off
after an over current condition occurs. Whereas OCP of +5VSB shall turn the power supply into
“hiccup mode” until the OCP condition removed. The values are measured at the PSU harness
connectors and shall not be damaged from repeated power cycling in this condition. There shall
be current sensors and limit circuits to shut down the entire power supply if the limit is exceeded.
The limits are listed below:
