摘要： The present invention provides a method for stream testing by a switching hub including the steps of generation a test data stream by the switching hub and testing a plurality of DUTs by using the test data stream. A first port of the switching hub transmits port mirroring to a second port of the switching hub. A packet is transmitted through a physical cable from the first port. The first port and the second port are added to a first virtual local area (VLAN) in a native manner. The second port receives a test packet in a self-loop mode. The test data stream is created by repeatedly transmitting the test packet from the second port. In addition, the present invention further provides a system for stream testing by a switching hub.

摘要： A hybrid power supply architecture including a microcontroller, a linear regulator, a first current sensing unit, a second current sensing unit, a switching regulator, a PWM controller and a hybrid output stage is disclosed. The linear and switching regulators respectively perform linear and switching regulation according to a first enable signal and a second enable signal generated by the microcontroller to generate a linear output power and a switching output power. The first and second current sensing units respectively generate a first current sensing signal and a second current sensing signal by sensing the linear and switching output powers. The microcontroller receives the first and second current sensing signals to determine a loading state. The switching regulator is enabled to actuate in case of heavy loading, and particularly the linear regulator is shut off only when the switching output power is stable, thereby implementing the best conversion efficiency.

摘要： The present disclosure provides a cable management arm and a rack applying the cable management arm. The cable management arm includes: a left cable management assembly, a right cable management assembly, a connection assembly, and an elastic assembly. When a chassis in the rack is pulled out of the rack, the elastic assembly causes the left cable management assembly and the right cable management assembly to move following the movement of the controller at the rear of the chassis in the pulling out direction, and causes the left cable management assembly and the right cable management assembly to reset due to elastic force. The connection assembly and the elastic assembly assist the movement of the left cable management assembly and the right cable management assembly to cause their resetting, and ensure them to move in an approximately horizontal space.
