A server rack system includes a management network switch, servers, a power supply unit, fan units, and an integrated management module (IMM). Management network ports of baseboard management controllers (BMCs) of the servers are connected to the management network switch. A management network port of the power supply unit is connected to the management network switch. Management network ports of the fan units are connected to the management network switch. A management network port of the IMM is connected to the management network switch. The IMM communicates with the BMCs of the servers, the fan units, and the power supply unit through the management network switch, so as to obtain operation states of the servers, the fan units and the power supply unit, or control operations of the servers, the fan units and the power supply unit.
