2.6 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.
Table 2-22 lists all of the signals which are part of the Itanium 2 processor power pod connector.
Warning: If the power supply cannot supply the voltages requested by the components in the Itanium 2
processor, then it must disable itself.
Figure 2-4 shows the top and bottom views of the power tab connector. The processor ground,
