Abstract: Examples of the disclosure provide a smart angled mounting piece and an angled mounting piece assembly. By providing switching units and identification circuits in the smart angled mounting piece, when one or more of the switching units are triggered by the auxiliary member, an identification circuit electrically connected to the triggered switching unit and an identification circuit electrically connected to a switching unit that is not triggered collectively generate a logic signal characterizing the position at which the electronic device is installed to the cabinet, and the logic signal is transmitted to the electronic device through the communication module. The manager may know the position of the current electronic device in real time, without the need to specifically provide position acquisition elements on the cabinet, and without the need to install a separate management system on the back-end server, simplifying the difficulty of device management.

Abstract: An electronic device includes a group of first cards and a group of second cards, wherein the group of first cards and the group of second cards are arranged orthogonally. An air path extends between a front part and a rear part of a chassis and a fan is positioned on at least one side of the group of second cards. An opening is formed in a second card to connect an air inlet of the fan with the air path extending between the front part and the rear part of the chassis.

Abstract: The present invention provides a method for forwarding data in the Ethernet, an Ethernet physical layer cross apparatus, an Ethernet Media Access Control (MAC) layer cross apparatus, an Ethernet IP layer cross apparatus and cross cascade systems. In the method of the present invention includes the following features: configuring cross relationships between network device interfaces; determining whether an interface has a cross relationship with other interfaces according to the cross relationships configured after receiving data from the interface; sending the data to an interface which has a cross relationship with the interface from which the data is received if the interface from which the data is received has a cross relationship with other interfaces; and proceeding with existing forwarding processing in each layer if the interface from which the data is received does not have a cross relationship with other interfaces.

Abstract: The invention discloses a method for dynamic allocation of slot bandwidth on a switch. First, the method sets that number of slots for dynamic allocation bandwidth is N and bandwidth needed to be dynamically allocated is B. Secondly; the method defines a minimum allocated bandwidth unit being ?B, according to requirement. Then, the method sets B/?B pieces of N-selected-one devices on main switch board. Further, the method allocates the bandwidth B to all N-selected-one devices on the main switch board, and makes input bandwidth of every N-selected-one device being N*?B. Finally, the method outputs strobe signal from a control logic chip to control said N-selected-one device, and bandwidth is allocated to the slot. The method, proposed by the invention, makes that bandwidth from service processing board slot to the main switch board can be dynamically allocated, and bandwidth allocated to each slot is flexible.

Abstract: The invention discloses a method for dynamic allocation of slot bandwidth on an exchange. First, the method sets that number of slots for dynamic allocation bandwidth is N and bandwidth needed to be dynamically allocated is B.
