A server includes a motherboard, a first test unit, and an indication device. The first test unit is connected to a first voltage terminal of the motherboard to receive a first voltage. The first test unit determines whether the received first voltage is within a range between a first predetermined voltage and a second predetermined voltage. If the first voltage is not within the range between the first predetermined voltage and the second predetermined voltage, the indication device indicates that the first voltage is abnormal.

A first output pin of a microcontroller is connected to a control pin of a high speed switch chip. A second output pin of the microcontroller is connected to two control pins of first and second switch chips. Two output pins of the high speed switch chip are connected to two input pins of the first switch chip. Two input pins of a third switch chip are connected to two output pins of the second switch chip. Two control pins of the third switch chip are connected to a third output pin of the microcontroller. Three input pins of a bus switch chip are connected to fourth to sixth output pins of the microcontroller. A load board is connected to six output pins of the bus switch chip and four switch pins of the first and second switch chips.
