Method for providing power supply in standby phase

Abstract

A method for providing power supply in a standby phase is implemented by a computer system supporting specifications of an open operation plan, and comprises the following steps that: (A) a programmable logic unit sets a card signal related to an open operation card to a high level to enter a first mode; (B) when the computer system is in the first mode, a substrate management control unit judges whether a standby power supply is insufficient or not; (C) when the standby power supply is judged to be insufficient, the substrate management control unit transmits a trigger signal to the programmable logic unit; (D) when the programmable logic unit receives the trigger signal, the programmable logic unit transmits a notification signal to a power supply unit so as to enter a second mode; and (E) when the computer system is in the second mode, the power supply unit provides a main power supply for the open computing card.

Description

technical field [0001] The invention relates to a method for providing power, in particular to a method for providing power required by a computer system in a standby phase. Background technique [0002] The standby power provided by the existing server power supply has a voltage of 12V and a current between 1.5A and 2A. For the application of server products in the past, the supply capacity of standby power is sufficient to supply It is used by the server in standby state. However, as new interfaces and devices continue to be introduced, the specifications of the above-mentioned power supplies are gradually unable to meet the requirements of some system designs. The specifications of the Open Compute Project (OCP) v3.0 For example, 1.5A of current is required in standby mode, plus about 0.5A required by the fan and the original design of the system (platform path control, baseboard management controller, Gigabit Ethernet transceiver (PHY), etc.. .) The required standby po...

However, as new interfaces and devices continue to be introduced, the specifications of the above-mentioned power supplies are gradually unable to meet the requirements of some system designs. The specifications of the Open Compute Project (OCP) v3.0 For example, 1.5A of current is required in standby mode, plus about 0.5A required by the fan and the original design of the system (platform path control, baseboard management controller, Gigabit Ethernet transceiver (PHY), etc.. .) The required standby power is about 1A, and the total 12V standby power requirement is about 3A. The power supply of the existing server cannot meet the requirements of the OCP v3.0 system design in the standby state, so it is necessary to propose a solution Program
