Abstract
Method and apparatus for monitoring and controlling electrical current delivered to a computer subsystem are provided. One embodiment provides a method for detecting a short circuit in a computer subsystem, comprising: obtaining a measured current which is supplied to the computer subsystem during one or more time periods; determining an expected current utilized by the computer subsystem for the one or more time periods; and determining whether a short circuit condition exists based on a comparison between the measured current and the expected current. The method may further comprise terminating electrical power supplied to the computer subsystem.
Claims20
A method for detecting a short circuit in a computer subsystem, comprising:
- obtaining a measured current which is supplied to the computer subsystem during one or more time periods;
- determining an expected current utilized by the computer subsystem for the one or more time periods;
- and
- determining whether a short circuit condition exists based on a comparison between the measured current and the expected current.
A signal bearing medium, comprising a program which, when executed by a processor, performs an operation for detecting a short circuit in a computer subsystem, the operation comprising:
- obtaining a measured current which is supplied to the computer subsystem during one or more time periods;
- determining an expected current utilized by the computer subsystem for the one or more time periods;
- and
- determining whether a short circuit condition exists based on a comparison between the measured current and the expected current.
A system for detecting a short circuit in a computer subsystem, comprising:
- a current monitor disposed on a power regulator for monitoring electrical current supplied to the subsystem;
- a control chip disposed on the subsystem for monitoring operations performed on the subsystem;
- and
- a service processor connected to receive information from the current monitor and the control chip, the service processor configured to:
- obtain a measured current which is supplied to the computer subsystem during one or more time periods;
- determine an expected current utilized by the computer subsystem for the one or more time periods;
- and
- determine whether a short circuit condition exists based on a comparison between the measured current and the expected current.
