Problems solved by technology

[0005] In addition, in order to implement services such as dynamic VLAN division, the NP needs to configure the switch chip. If the NP and the switch module are made into two cards, it is necessary to add a switch module configuration channel on the backplane, so it is necessary to change the AMC card to The pin definition of the backplane and the link relationship between the two slots on the backplane, so that the AMC card and the backplane become customized, and cannot be interconnected with the standard Micro-TCA backplane or board

Embodiment 1

[0020] See attached figure 1 , which is a schematic structural diagram of the MCH card provided by the technical solution of this embodiment.

[0021] Depend on figure 1 It can be seen that the MCH card provided by the technical solution of this embodiment is composed of a line card module, an NPU module, a switch module, and an IPMI module. There are eight 1000BASE-X connections between the line card module and the NPU module, and 8 1000BASE-X connections between the NPU module and the switch module. 8 1000BASE-X and MII (Media Independent Interface) management channel connections, 12 1000BASE-X connections between the switch module and the backplane golden finger. The external interface of the line card module is 8 Gigabit electrical ports, or 8 Gigabit optical ports.

[0022] The technical solution of this embodiment provides that the size of the MCH card is consistent with the Micro-TCA specification; its golden finger pin function is also consistent with the Micro-TCA s...

Abstract

The invention relates to an application of a Micro-TCA system, more particularly relates to a multifunctional, economical and manageable MCH required by the system, belonging to the technical field of network processing. The MCH card is composed by a line card module, a NPU module, an exchange module and an IPMI module; the line card module is connected with the NPU module through a gigabit Ethernet, the NPU module is connected with the exchange module through the gigabit Ethernet and a configuration channel, the exchange module is connected with a backboard golden finger through the gigabit Ethernet. An external interface of the line card module is a gigabit electric hole or a gigabit optical hole. The integrated circuit board size and golden finger pin functions of the Micro-TCA system are consistent with the Micro-TCA criterion. The invention disposes the high bandwidth channel among a plurality of integrated circuit boards into one integrated circuit board, efficiently solving the problem about shortage of bandwidth among the integrated circuit boards, realizing less slot positions and compacter system frame, and reducing the cost of entire Micro-TCA system; and the system reliability is improved by lessening the backboard connections, removing power source loss of the line card and the NPU card.

Description

technical field [0001] The invention relates to an application of a Micro-TCA system, in particular to an economical, multi-functional and manageable MCH required by the system, and belongs to the technical field of network processing. Background technique [0002] The PCI Industry Association formulated the Micro-TCA standard in July 2006, which expanded the application range of AMC (Advanced Mezzanine Card) and provided high performance, high reliability, low price, and modularization for the communication field and industrial control field. , Compact general-purpose hardware platform. The Micro-TCA system mainly includes AMC card, MCH card (MicroTCA Carrier Hub), and PM card (Power Module). These three cards can form a Micro-TCA system in various frame forms and very flexibly. The system framework can choose various forms such as 1U chassis, 2U chassis, 4U chassis, blade rack type, etc. According to the needs of reliability, the system with high reliability requirements,...
