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.
Claims18
A method comprising:
- detecting if one of a plurality of processor modules is present based on signals from the processor modules;
- monitoring a voltage level of one of a plurality of power supply modules, said one of the power supply modules corresponding to said one of the processor modules;
- and
- generating a control signal to turn off power if said one of the processor modules is present and said voltage level is outside an operating range.

An apparatus comprising:
- a detector to detect if one of a plurality of processor modules is present based on signals from the processor modules;
- a voltage monitor to monitor a voltage level of one of a plurality of power supply modules, said one of the power supply modules corresponding to said one of the processor modules;
- and
- a control circuit coupled to the detector and the voltage monitor, the control circuit to generate a control signal to turn off power if said one of the processor modules is present and said voltage level is outside an operating range.
1 more element
A system comprising:
- a plurality of processor modules;
- a plurality of power supply modules for providing power to said plurality of processor modules;
- and
- a checking circuit for checking an installation of the plurality of power supply modules, the checking circuit including:
- a detector to detect if one of the processor modules is present based on signals from the processor modules,
- a voltage monitor to monitor a voltage level of one of the power supply modules, said one of the power supply modules corresponding to said one of the processor modules, and
- a control circuit coupled to the detector and the voltage monitor, the control to generate a control signal to turn off power if said one of the processor modules is present and said voltage level is outside an operating range.
