Processor Power Modules on CPU Boards

Processor Power Modules on a processor (CPU) board decode the voltage
requirements for each Pentium Pro processor and supply tightly regulated DC
voltage to the processors.

The modules can be placed in parallel configuration to provide redundant
operation. With one or two processors present on a board, the Processor Power
module slot nearest the processor slot and the outer edge of the board supports
that processor. Figure 5-3 illustrates configuration.
A 5V Processor Power module placed in the center slot operates in parallel
with the modules on both sides and provides redundancy for either (one) or
both of the other Processor Power Modules on that board, providing the
processors are the same frequency and have the same voltage rating.
IMPORTANT:
the end slot(s) are populated with functional module(s) to ensure normal
system operation. Promptly obtain a replacement from your Authorized Compaq
Service Provider.
