When input power is applied to the power supply, any initial current surge or spike of 10 ms or less should not
exceed 55A. Any additional inrush current surges or spikes in the form of AC cycles or multiple AC cycles
greater than 10 ms, and less than 150 ms, must not exceed 25A.
The power supply has DC outputs of 12 V and 3.3 VSB. The 12 V main power is distributed through the server
and is converted locally at the point-of-load using embedded Voltage Regulator Module (VRM) converters. The
power supply is capable of power-safe monitoring.
The DC output voltages remain within the ranges shown in the following table when operating at steady state
and dynamic loading conditions. These limits include the peak-peak ripple/noise.
