Description

A kind of method and system monitoring motherboard power supply and signal condition
Technical field
The present embodiments relate to server monitoring administrative skill fields, and in particular to a kind of monitoring motherboard power supply and signal The method and system of state.
Background technique
During server design, it is often necessary to be monitored to the power supply on mainboard.When motherboard power supply breaks down When, where needing to measure the problem of finding out power supply step by step using avometer, but this existing misarrangement method is time-consuming and laborious, Efficiency is lower.
In existing server architecture, motherboard power supply is generally by Complex Programmable Logic Devices (CPLD) come control mainboard Power supply timing, signal is all by the enable signal EN (Enable) and PG (Power Good) of main on board supply voltage-stablizer (Power VR) It is linked into Complex Programmable Logic Devices, and general EN and PG signal is all that high level is effective.When the power supply on mainboard is steady When depressor needs to be turned on, CPLD can draw high enable signal, if power regulator receives after enable signal successfully by needs Voltage output, then PG signal is drawn high by power regulator, and CPLD thinks the power regulator after receiving the PG signal drawn high Success exports level, is next then turned on next power regulator.
Based on above-mentioned existing motherboard design, the present invention propose it is a kind of monitoring motherboard power supply and signal condition method and be System carries out motherboard power supply using Complex Programmable Logic Devices and signal condition monitors, improves monitoring accuracy rate and debugging efficiency.
