Notes

1. Power Supply Efficiency affects the current draw in AC Watts from the branch circuit. As efficiency increases, the current draw in AC Watts decreases.
2. To calculate maximum theoretical current draw in AC Watts, multiply the maximum power supply output in DC Watts by the reciprocal of the power supply efficiency.
3. Theoretical values are typically higher than published values which are based on measured outputs under controlled test conditions.
4. 300-1945 was added to option X8428A-Z in May 2007. (WO_36947)
5. The A203 (300-1757/300-1945) is not NEBS qualified for use in the Netra X4200 M2.
6. Mixing A203 (300-1757/300-1945) and A214 (300-1848/300-1852) is supported on Sun Fire V215 and V245 only.
   Mixing these power supplies is not supported on any other platform.
