Abstract
A server system and controlling method for an operation timing after being powered up are disclosed. The sever system controls a reset signal to have a voltage lower than a first voltage value by introducing a voltage monitoring module when a work power lower than a voltage threshold. On the other hand, when the work power voltage increases to higher than the voltage threshold of the voltage monitoring module, the voltage monitoring module controls the reset signal voltage to be higher than a second voltage value, whereby achieving in a technical efficacy of stable initialization and reset of the server.

A server system, comprising:
- a power management module, wherein when the server is powered up, the power management module generates a work power and a power good signal and a voltage of the work power changes from a low voltage to a high voltage;
- a logic control module, receiving the work power and the power good signal, and generating a reset signal upon receiving the power good signal;
- a voltage monitor module, having a voltage threshold, controlling a voltage of the reset signal lower than a first voltage when the voltage of the work power lower than the voltage threshold, and until the voltage of the work power higher than the voltage threshold controlling the voltage of the reset signal higher than a second voltage and maintained for a first period (S);
- and
- a baseboard management controller, connected electrically to the logic control module, and beginning to be reset and initialized when the logic control module controls the voltage of the reset signal to change from higher than the second voltage to lower than the first voltage, and managing and monitoring the server system after the initialization.
