2.6Power 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 2-22lists all of the signals which are part of the Itanium 2 processor power pod connector.

Table 2-22. Itanium® 2 Processor Power Pod Connector Signals

Group Name	Signals
Power Pod Connector	OUTEN, CPUPRES#, PPODGD#, VCC, VCCMON, GND, VSSMON, VID[4:0]

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

Figure 2-4shows the top and bottom views of the power tab connector. The processor ground, VSS,Processor, connection is provided on the power tab connector as well.
