  • Patent number: 9304884
    Abstract: A test apparatus applicable to a server includes a processing unit, a control unit, a switch unit and a power relay unit. The processing unit outputs a reset signal and a processing signal. The control unit includes a first physical layer chip performing a first communication protocol, and a second physical layer chip performing a second communication protocol. The switch unit receives a working voltage and a processing signal to select a powering signal or a disconnection signal to output. The power relay unit receives the powering signal or the disconnection signal. When the power relay unit receives the powering signal, the server performs a test task on the first physical layer chip. When the power relay unit receives the disconnection signal and the processing unit outputs the reset signal to the control unit, the server performs the test task on the second physical layer chip.

  • Publication number: 20140143511
    Abstract: An interface conversion device, applicable to a storage device, includes a first connection port, a second connection port, a measuring unit and a processing unit. The first connection port transmits a first signal and a power signal via a first communication interface. The second connection port transmits a second signal and the power signal to the storage device via a second communication interface. The first communication interface and the second communication interface are different from each other. The measuring unit receives the power signal from the first connection port to measure the power signal and produce a measurement signal. The measuring unit outputs the power signal to the second connection port. The processing unit receives and converts the first signal into the second signal and outputs the second signal via the second connection port. The processing unit receives the measurement signal to calculate a power consumption value.
