摘要： A fault identification apparatus includes a detector and a plug interface connected with the detector, where the plug interface includes a first measuring terminal and a second measuring terminal; when fault identification is performed for a PSU in a communication apparatus under test, the first measuring terminal is connected with a first end of the PSU, and the second measuring terminal is connected with a second end of the PSU; and the detector obtains a voltage value between the first measuring terminal and the second measuring terminal to determines whether a failure occurs to the PSU based on the voltage value.
