Rack server system

A rack server system, comprising:

• a plurality of server nodes;
• a power supplying module configured to output a first power source;
• and
• a rack management module, comprising:
• a management module;
• a detection module coupled with the power supplying module and configured to output a detection signal according to the first power source;
• an isolation module coupled with the power supplying module and the detection module and configured to receive the first power source and according to the detection signal, determine whether to output a second power source to the management module;
• an energy storage component configured to storing electricity;
• a charging module coupled with the energy storage component, the isolation module, and the detection module and configured to receive the second power source and according to the detection signal, determine whether to output a third power source to charge the energy storage component;
• and
• a discharging module coupled with the energy storage component, the detection module, and the management module and configured to receive a fourth power source from the energy storage component and according to the detection signal, transfer the electricity released from the energy storage component to provide a fifth power source to the management module;
• wherein when the power supplying module operates normally, the detection module outputs the detection signal at a first voltage level indicating that the first power source is normal, the isolation module outputs the second power source according to the detection signal, the charging module outputs the third power source to charge the energy storage component according to the detection signal, and the discharging module does not provide the fifth power source according to the detection signal;
• when the power supplying module operates abnormally, the detection module outputs the detection signal at a second voltage level indicating that the first power source is abnormal, the isolation module stops outputting the second power source according to the detection signal, the charging module stops outputting the third power source to charge the energy storage component according to the detection signal, and the discharging module provides the fifth power source according to the detection signal;
• when the power supplying module operates normally, the management module receives the second power source and operates normally;
• and
• when the power supplying module operates abnormally, the management module receives the fifth power source and operates normally.
