The present invention relates to an electronic apparatus, which includes at least two node modules; a shared I/O module, having a first I/O interface connected with an external device and a second I/O interface electrically connected with the at least two node modules; and a switching module connecting the at least two node modules and the shared I/O module, used to cause the shared I/O module to communicate with one node module in the at least two node modules through the second I/O interface according to a selection signal when receiving the selection signal. The shared I/O module integrates multiple communication ports, and can switch the node module communicating with the shared I/O module according to a selection signal, and the shared I/O module can design a shared I/O module combined by multiple different ports in advance, to perform corresponding replacement according to user needs; the present invention meets high-integration modular design of the electronic apparatus, and ensures stability and high efficiency of communications between the modules.
The present invention relates to an electronic apparatus, the back plate, the I/O module, the power supply, the node module and the like are reasonably and neatly laid out in the case, so that more modules can be laid out in a limited case space, thus having a high utilization rate and a low cost. Besides, the I/O module, the power supply module and the node module are separately designed, and the modules cooperate with each other; the modules are snap structures, and can be assembled and disassembled by hand, which increases operation and maintenance efficiency. Moreover, the completion of the signal transmission among different modules mainly depends on the golden finger or the high-speed back plate connector, thus the case is clean and neat inside.
The present invention relates to an electronic apparatus, which lays out an I/O module and a power supply module in a case reasonably and neatly, and specifically causes the I/O module and the power supply module to be set in a first receiving space of the case with equal height and equal length, so that more modules can be laid out in a limited case space, thus having a high utilization rate and a low cost; moreover, the I/O module and the power supply module are separately designed, and the modules cooperate with each other; the modules are snap structures, and can be assembled and disassembled by hand, which increases operation and maintenance efficiency.
The present invention relates to an electronic apparatus, which integrates an adapter plate, a PCIE card and a fan into an input/output unit, communicates with other electronic elements in the electronic apparatus through the adapter plate in the input/output unit, and reasonably lays out elements in the input/output unit, so that more electronic elements can be laid out in a limited electronic apparatus case space, thus having a high utilization rate and a low cost. Moreover, the design of the internally integrated fan makes the input/output unit and the electronic apparatus have good heat dissipation effects, and the input/output unit may be designed as hot plug, facilitating replacement and maintenance of the whole input/output unit.

A rack structure for mounting a server in a server system with a slide channel and a retention groove, includes: a rack formed with one engagement element slidable non-removably within the channel; and a rotary rod having a first end connected pivotally to the rack via a pivot pin and a second end provided with a slide stick extending slidably into the groove. The rotary rod is rotatable about the pivot pin relative to the rack between a locking position, where the rotary rod is generally aligned with the rack while the slide stick engages a first end of the groove so as to retain the rack non-movably in the channel, and an unlocked position, where the rotary rod extends generally transverse to the rack while the slide stick engages a second end of the groove to permit sliding action of the rack within the channel.

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 minoring 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.

The present invention provides an operations, administration and maintenance (OAM) security authentication method and OAM packet transmitting/receiving devices. An OAM packet is authenticated by utilizing a random number and an authentication code. A threshold for the number of failed authentication is determined If the number of failed authentication is greater than the threshold, the random number will be updated. According to the present invention, OAM packets constructed by malicious users or tampered with may be detected to increase security of OAM packets and avoid a denial-of-service (DOS) attack.

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.
