Description
Technical field
The present invention relates to communication technical field, particularly a kind of method, system and device of loading monoboard fastener.
Background technology
Micro telecommunication and computer general hardware platform architecture (Micro Telecommunications ComputingArchitecture, MicroTCA) be (the PCI Industrial ComputerManufacturers Group of association of PCI industrial computer producer, PICMG) micro telecommunication of organizing to set up and computer general hardware platform architecture, MicroTCA utilizes advanced interlayer card (Advanced Mezzanine Card, AMC) come construction systems, support the AMC of hot plug can directly be inserted into the backboard of MicroTCA.MicroTCA mainly locatees low and middle-end,, the telecommunications or the computing application that require little physical size relatively responsive to cost.The main application comprises wireless base station, router, media gateway etc.MicroTCA fundamental norms title is MicroTCA.0, has defined the content such as machine frame structure, management, power supply, heat radiation, interconnection of MicroTCA.
Advanced interlayer card (Advanced Mezzanine Card, AMC) be the general interlayer card that can support hot plug of PICMG tissue definition, particular type comprises types such as Digital Signal Processing (DSP) AMC, central processing unit (CPU) AMC, network processing unit (NP) AMC, interface AMC, storage AMC.AMC can directly be inserted on the backboard of MicroTCA and use, and constitutes the MicroTCA system.The AMC standard comprises AMC.X series standard standard, has defined the contents such as structure, management, power supply, heat radiation, interconnection and switching network suggestion of AMC.
IPMI (Intelligent Platform Management Interface, IPMI) be the intelligent platform management interface standard of releasing for the availability index that improves server, initial purpose is that functions such as equipment control, transducer/incident management, user management, fan frame/power shelf management, remote maintenance are provided for server.MicroTCA standard and AMC standard are all with the management regulation of IPMI normalized definition for following.
(Intelligent Platform Management Bus IPMB), is based on the general designation of the management bus of IPMI standard to Intelligent Platform Management Bus.The IPMB bus is divided into two kinds again in MicroTCA, IPMB-0 and IPMB-L (Local Intelligent Platform Management Bus, local intelligent platform management bus).Wherein IPMB-0 connects MicroTCA bearer management controller (the MicroTCA Carrier Manager Controller in the MicroTCA system, MCMC) and strengthen module Management Controller (Enhanced Management Controller, EMMC), (MicroTCA Carrier Hub is MCH) to the management of power module and fan unit to realize the switching control module of MicroTCA.And MCMC in the IPMB-L connection MicroTCA system and module management controller (Management Controller, MMC).
MCH realizes each AMC is managed.MMC realizes the monitoring function of the AMC self depend on, finishes maintenance management to loading plate to cooperate MCMC.For example: MMC among the AMC collects the information of monoboard fastener, by the IPMB_L passage information of collecting is reported MCMC on the MCH then.MCMC manages, safeguards loading plate by analyzing the information that each MMC reports.
At present, how quick, realize that easily the JTAG remote maintenance of MMC monoboard fastener, loading become the problem that MicroTCA must face.Existing MicroTCA standard is by JTAG Switching Module (JTAG Switch Module, JSM) JTAG remote maintenance, the loading of realization MMC monoboard fastener.Be achieved in that specifically that referring to shown in Figure 1 MCH comprises MCMC and JSM module, MCH connects AMC by backboard.During the upgrading of MMC monoboard fastener, the JSM module produces the JTAG signal and inputs to each AMC respectively, the file destination of redaction is burnt among each AMC in the MMC monoboard fastener by external JTAG socket, the MMC firmware code of operation redaction after MMC powers on, thereby realize that MCH loads each AMC veneer JTAG, professional control such as upgrading and maintenance.
From the prior art scheme as can be seen, when realizing that the MMC monoboard fastener loads, need on the MCH one independently the JSM module be inserted on the backboard, carry out the transmission of JTAG signal with AMC by the IPMB-L management bus.Because in this mode, MCH needs independently JSM module, therefore take the groove position resource among the MCH, also, therefore also increase MicroTCA platform cost owing to increased the JSM module, simultaneously, because when realizing the JSM module and MMC among the AMC communicates by letter, if 5 jtag bus data-signal ports of the needs of the MMC among JSM module and each AMC, each MicroTCA backboard need be introduced 60 jtag bus data-signal ports at most so, therefore, this mode takies the port resource of backboard anxiety.Simultaneously, each AMC also needs to provide 5 special-purpose JTAG load signal lines, has increased connector density and cost.
