A method for self-starting up plate of exchanger includes resetting plate, loading program and /or data from storage in plate by plate, running plate after loading is finished, judging whether program and data in said storage is usable or not before program and data are loaded, loading program and data not usable in storage from background server by plate if program and/or data in storage is not usable.
Description
Technical field
The present invention relates to the method for a kind of equipment plate self-starting, the method for loading procedure and data when relating in particular to a kind of switchboard plate self-starting.
Background technology
Along with present switch adopts the modular structure mode, the program of a lot of veneers no longer is simply to be solidificated in the veneer, but adopts from background server loading monoboard program to veneer, and the maintenance function of veneer and expanded function all are improved.Only there is the BIOS boot in the veneer, veneer loads to background server BAM application, the program of finishing loads, finish data load, (program and data can be compressed at background server earlier for program and data, and then in the veneer decompression) there is the memory address that is placed on appointment, this memory address is exactly the start address of program run.Jump to the program origin from bios program at last, the operation monoboard programme.
Many veneers reset once more or plug after, veneer can jump in the boot of BIOS and move, therefore program that loads in the veneer and data can lose, so veneer all can load to background server BAM application once more, and the time length of the process that loads and the size of monoboard programme and data have relation, under the certain situation of communication bandwidth, the program of veneer and data are big more, and the loading consumed time is just long more.Switch or other communication programs were less in the past, the business function that provides is also comparatively simple, the time that loads cost is not long, along with the function of switching equipment constantly increases, program and data are also increasing, according to the mode that loads fully veneer is reruned like this, the professional time of recovering again is long, has no longer met present device requirement.
Describe switch in the prior art among Fig. 1 and realized the flow process of board resetting and loading procedure and data, the realization of existing switch generally all is as the back administrative unit with background server, can directly be connected between background server and the veneer with the LAN netting twine, also can between background server BAM and veneer, connect by switch Front Administration Module FAM, can adopt the LAN netting twine to be connected between background server BAM and the Front Administration Module FAM, Front Administration Module FAM can adopt the HDLC link to be connected with veneer; Monoboard programme that veneer loads in the switch and data all are to exist in advance in the BAM, veneer is after setting up communication channel in the switch, to backstage BAM application loading monoboard program and data, after loading was finished, veneer can move the program of loading and use corresponding data.
If BAM (background server)/WS (client workstation) issues reset command to the veneer that moves and (also exists in the situation of the enterprising horizontal reset of veneer in the prior art, as open the reset switch of veneer, do not need BAM/WS to send out reset command), after veneer is received reset command, program out of service, original state is jumped in board resetting, once more to backstage BAM application loading procedure and data; BAM confirms to load, and returns load information; Next the loading monoboard program reloads the veneer data after monoboard programme has loaded; After the veneer data load was finished, veneer returns to load to be confirmed; Veneer brings into operation.
But can there be some shortcomings in above-mentioned existing scheme, BAM is the gateway of machine and external information in return, switch is very high to performance and the stability requirement of BAM, provide the dependence of manufacturer very strong to BAM, and BAM is subject to outside world, as virus, hacker etc., and the difficult shortcoming that expands.
Along with the function of switching equipment constantly increases, program and data are also increasing, according to the mode that loads fully veneer are reruned like this, and after veneer loading procedure and the data, the time that normally goes into operation is long, has no longer met present device requirement.
