Abstract: An electronic device is connected to an Inter-Integrated Circuit (I2C) expander using an I2C controller of the electronic device. The I2C expander is connected to the servers. Each of the servers corresponds to an identification number. Method of controlling baseboard management controller (BMC) of servers using the electronic device includes receiving identification numbers and determining an operation mode corresponding to each of the identification numbers. According to the identification numbers, each of the identification numbers corresponding to a determined server, servers are determined. The electronic device is controlled to connect to the determined servers. A restart server group comprising one or more determined servers whose operation modes are to restart BMC is determined. A restart signal is transmitted to the restart server group. A BMC of each of the one or more determined servers in the restart server group are controlled to restart according to the restart signal.

Abstract: An electronic device and method for testing an audio module of a network device including establishing a first connection between an audio output interface of the electronic device and a microphone interface of the network device. First audio data of a test file is transmitted from the audio output interface to the microphone interface through the first connection. An audio card of the network device records the first audio data output by the microphone interface to generate second audio data, and transmit the second audio data to the electronic device through a network. The second audio data is compared with the first audio data in response to receiving the second audio data by the electronic device. The audio module is determined to be normal if the second audio data matches the first audio data.
