Notes

1. Airflow of the A239C Power Supply is from the power connector to the ejector.
   
2. Power Supply Efficiency affects the current draw in AC Watts from the
   branch circuit. As efficiency increases, the current draw in AC Watts
   decreases.
3. 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.
4. Theoretical values are typically higher than published values which are
   based on measured outputs under controlled test conditions.
5. ILOM 3.0.12.2.d, Patch 145667-02, sets the minimum power supply fan speed to
   50% to prevent Disk Drive overheating.
6. The SPARC T3-2 and T4-2 do not support the 100-127Vac input range.
