Abstract
A multi processor computer system includes processors in processor receptacles , and voltage modules and voltage module receptacle . The system accepts both direct voltage processors powered directly from the system power plane, and regulated voltage processors which require a voltage regulator . The regulated voltage processors require the voltage regulator while the direct voltage processors cannot operate with a voltage regulator. Voltage module control circuit tests and compares processor type signals from the processor receptacles and voltage module type signals from the voltage module receptacles, and produces a voltage validation signal which indicates the presence of a mismatch between any of the processors and its respective voltage module. The voltage validation signal modifies the conventional processor presence signal from the processor receptacles if a mismatch exists, preventing the system from being powered on.
