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.

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.

An anti-backflow device for a fan unit, which is fabricated by cutting a rectangle thin plate, includes: a plate body defining an air outlet to permit air outflow upon activation of the fan unit, and having at least two inner peripheral sides; a plurality of connection arms; and a plurality of blades. Each blade is connected a pair of the connection arms, which are in turn connected to two connecting holes formed in the inner peripheral sides of the plate body.


Disclosed is a method for generating a multi-protocol fault management (FM) packet by using a field-programmable gate array, including: setting information related to FM in a plurality of local maintenance entity group end points (LMEPs); performing a polling process of the plurality of LMEPs according to the packet types after obtaining send instructions related to a certain packet type; determining a protocol type of the plurality of LMEPs; obtaining information related to the protocol type; acquiring information related to the packet type under the protocol type; generating a corresponding number of FM packets in accordance with the information related to the protocol type and the at least one set of field information related to the packet types; and outputting the FM packets. The method enables transmission of CCM, LCK and AIS packets under ETH, ITU and IETF packets to be achieved. Therefore, compatibility and competitiveness of products are improved.


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.

Celestica | Date: 2014-09-19

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.
