2.2.1.1
Power Supply Mechanical Outline
Both AC and DC power supplies are 3.30”wide by 1.60” high by 9.60”in length. The output cable
bundle is separated into two cables; one cable with two connectors for the serverboard, and the
other with a connector for the backplane which in turn powers the HDD’s. The backplane also
has a CDROM power connector.
2.2.1.2
Power Supply Fan Requirements
The power supply relies on cooling provided by two 40mm fans mounted in the chassis in front of
the power supply. These fans are monitored by hardware on the motherboard and the Advanced
Server Management software that comes on the Resource CD in the accessory kit.
2.2.1.3
AC Power Line
The system is specified to operate over two input voltage ranges that are automatically selected
and rated from 100-120VAC and 200-240VAC, at 50 or 60Hz. The power supply incorporates
Power Factor Correction (PFC) as a standard feature. The system is tested to meet these line
voltages, and has been tested (but not specified) at +10% and -10% of the voltage ranges, and
±
3Hz on the line input frequency. The system is specified to operate without error with line source
interruptions not to exceed 20 milliseconds at nominal line conditions and full power supply output
load. The system is not damaged by AC surge ring wave to 2.5kV/500A. This ring wave is a
100kHz damped oscillatory wave with a specified rise-time for the linear portion of the initial half-
cycle of 0.5
µ
sec. Additionally, the system will not be damaged by a unidirectional surge
waveform of 2.0kV /3000A, with a 1.2
µ
sec rise time and 50
µ
sec duration. Further details on
these waveforms can be obtained in ANSI/IEEE STD C62.45-1987.
