Abstract

The invention provides a method and an apparatus for preventing an over-current protection malfunction. The method and the apparatus are applied to a power supply. The method comprises the steps of receiving a startup signal of electric equipment taking the power supply as a power source; sending out a first control instruction according to the startup signal, thereby disabling an over-current protection function of an auxiliary power supply line on the power supply; judging whether a duration of disabling the over-current protection function reaches a preset first standard duration or not; and if yes, sending out a second control instruction to recover the over-current protection function. The apparatus comprises a receiving unit, a function shielding unit, a first judgment unit and a function recovery unit. According to the scheme, the cost of the power supply can be reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for preventing misoperation of overcurrent protection. Background technique [0002] With the continuous development and progress of computer technology, servers are widely used in various fields of life and production due to their strong computing power, security and reliability. The power supply is an important part of the server, and the stability of its operation directly determines the stability of the server. In order to prevent the large current generated when the power supply fails to damage the main board of the server, the server power supply is usually equipped with an over-current protection function. Output power to protect the server motherboard. [0003] The server power supply includes a main power supply line and an auxiliary power supply line, wherein the auxiliary power supply line (Stand By) is used to start the power supply. When the ...
