Power Pod Connector Signals

Power delivery for the Itanium 2 processor is from a DC-DC converter called the "power pod". The
power pod consists of a DC-DC converter and a semi-flexible connector which delivers the voltage
to the processor.

Warning: If the power supply cannot supply the voltages requested by the components in the Itanium 2
processor, then it must disable itself.
