8 SPARC Enterprise T5120 and T5220 Servers Site Planning Guide • July 2009
Note – The maximum operating input current values are based on P / (V * 0.95),
where P=maximum operating input power, V=input voltage. Example: 662 / (110 *
0.95) = 6.33 A at 110 VAC. You can use this equation to calculate the maximum
operating input current for your specific input voltage.
