MicroTCA standard-based media server

Abstract

The invention relates to a telecommunication-level universal hardware platform, in particular to a micro telecom computing architecture (TCA) standard-based media server. In the media server, two paths of alternating current (AC) or direct current (DC) power are fixed on a case; the power is converted by a power module and then provided to an Oring circuit on a back panel to output 12V power to a load power system and a DC-DC power module; the power module outputs 3.3V power to a management power system; the load power system comprises 4 to 16 load power modules, and outputs 12V power to a microTCA carrier hub (MCH), an advanced mezzanine card (AMC) and a radiating fan; and the management power system comprises 2 to 14 management power modules, and outputs 3.3V power to the MCH and the AMC. In the media server, a microTCA standard power module is cancelled, a normal power module is used, and the management system is electrified by the MCH, so that the complexity and the production cost for power supply of the system are reduced; and a hot-plug circuit is arranged on the back panel, so that a hot-plug function is realized.

Description

technical field [0001] The invention relates to a carrier-grade general hardware platform, in particular to a media server based on the MicroTCA standard and compatible with standard AMC boards. Background technique [0002] As a supplement to the AdvanedTCA standard, a popular modular hardware platform standard in the industry today, the MicroTCA hardware technology standard is mainly aimed at application fields such as network communication, medical image processing, embedded control and military industry. Its high bandwidth, modularity and flexibility And the advantages of high cost performance have been more widely used, and become the preferred standard for building high cost performance modular standard hardware platforms today. [0003] A typical MicroTCA system includes: 12 AMC (Advanced Mezzanine Card) modules, 1 or 2 MCH (MicroTCA Carrier Hub), interconnection backplane, power supply and cooling modules. AMC boards come in four forms according to their physical di...

Problems solved by technology

At present, most of the 19-inch MicroTCA chassis products on the market use standard MicroTCA power modules. Since the power module occupies the slot, this type of chassis can only support 10 full-height AMC boards. Four half-size AMC boards can also reach the capacity of 12 AMC boards in these chassis, but because the AMC board itself is very compact, the density of components on the board is very high, if it is to be made into a half-height size, it must be On the one hand, the height of components is difficult to meet the requirements. In addition, it is very difficult for half-height AMC boards to dissipate heat, so the supply of half-height AMC boards is scarce. For users who generally use the MicroTCA standard, only 10 AMC boards can be used. The two half-height slots are not used, and the capacity of 12 AMC board cards stipulated in the standard cannot be reached

[0005] In the standard MicroTCA, the power supply of the AMC board is realized by the control of the power module. It is necessary for the power module to communicate with the MCH and AMC board to supply power to the functional modules. It also involves some complicated IPMI communication protocols, so that the power supply The module structure and use are very complicated, and it is difficult for general manufacturers or users to develop and use; it often takes a long time to debug the power supply board to make the AMC board supply power; and the products provided by different production units have the power module application protocol They are different and have poor compatibility with each other, which brings difficulties and troubles to users in use, and is not conducive to the promotion and use of products.
