Note: These values are for reference only. The processor EMTS contains the actual
specifications for the processor. If the values found in the EMTS are different then those
published here, the EMTS values will supersede these, and should be used.
8.4 Power Supply Specifications
This section provides power supply design guidelines for an system using either the Intel Server
Board SE7320SP2 or SE7525GP2, including voltage and current specifications, and power
supply on/off sequencing characteristics.

8.4.1 Power Timing
This section discusses the timing requirements for operation with a single power supply. The
output voltages must rise from 10% to within regulation limits (T
vout_rise
) within 5 ms to 70 ms.
The +3.3 V, +5 V and +12 V output voltages start to rise approximately at the same time. All
outputs must rise monotonically. The +5 V output must be greater than the +3.3 V output during
any point of the voltage rise, however, never by more than 2.25 V. Each output voltage shall
reach regulation within 50 ms (T
vout_on
) of each other and begin to turn off within 400 ms (T
vout_off
)
of each other.
