Abstract
The present invention discloses a method and apparatus for checking an installation of a plurality of power supply modules in a multiprocessor system having a plurality of processor modules. A detector detects if one of the processor modules is present. A voltage monitor monitors the voltage level of one of the power supply modules which corresponds to the processor module. A control circuit generates a control signal to turn off the power if the processor module is present and the voltage level is outside an operating range.
