Server system and auto-reset method of the same

An auto-reset method applied to a server system, comprising:

• making a power control circuit of the server system operate to generate a control signal;
• making a power processing circuit of the server system operate according to the control signal to receive a first power source and generate a second power source;
• making a CPLD of the server system receive the second power source and operate accordingly;
• making the CPLD conduct an update process and generating a power reset signal to a control circuit of the server system after finishing the update process;
• controlling the power control circuit to stop generating the control signal by the control circuit to turn off the power processing circuit to further disable the CPLD in a certain time period according to the power reset signal;
• and
• controlling the power control circuit to generate the control signal by the control circuit to activate the power processing circuit to further activate and reset the CPLD after the certain time period.

A server system having an auto-reset mechanism, comprising:

• a power control circuit used to generate a control signal;
• a power processing circuit operating according to the control signal to receive a first power source and generate a second power source;
• a CPLD (complex programmable logic device) which receives the second power source and operates accordingly and generates a power reset signal when the CPLD finishes an update process;
• a control circuit which controls the power control circuit to stop generating the control signal to turn off the power processing circuit, further disable the CPLD in a certain time period according to the power reset signal, and
• controls the power control circuit to generate the control signal to activate the power processing circuit, further activate and reset the CPLD after the certain time period.
