11.3 Processor Power Support

The Intel Server Boards SE7320EP2 and SE7525RP2 are designed to support the Thermal
Design Point (TDP) guideline for Intel® Xeon™ processors. In addition, the Flexible
Motherboard Guidelines (FMB) have been followed to help determine the suggested thermal
and current design values for anticipating future processor needs. Table 95 provides maximum
values for Icc, TDP power and T
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.

11.4 Power Supply Specifications

This section provides power supply design guidelines for a system using either the Intel Server
Boards SE7320EP2 or SE7525RP2, including voltage and current specifications, and power
supply on/off sequencing characteristics.

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
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
of each other.
