System Power Requirements

Table 3-3 “Power Requirements (without Support Management Station)” and Table 3-4 “Component Power Requirements (without Support Management Station)” list the AC power requirements for a Superdome and hp 9000 Superdome systems. These tables provide information to help determine the amount of AC power needed for your computer room.

Table 3-3 Power Requirements (without Support Management Station)

Requirements	Value	Comments
Nominal input voltage	200/208/220/230/240 (VAC rms)
Input voltage range (minimum - maximum)	200 - 240 (VAC rms)	Autoselecting (measured at input terminals)
Frequency range (minimum - maximum)	50/60 (Hz)
Number of phases	3
Maximum inrush current	90 (A peak)
Product Label maximum current, three-phase, four-wire	44 (A rms)	Per phase at 200-240VAC
Product Label maximum current, three-phase, five-wire	24 (A rms)	Per phase at 200-240VAC
Power factor correction	0.95 minimum
Ground leakage current (mA)	> 3.5 ma	See WARNING below.




	WARNING! Beware of shock hazard. When connecting or removing input power wiring, always connect the ground wire first and disconnect it wire last.
