For the purpose of the embodiment of the invention, the technical scheme and the advantages more clearly, with the lower portion of the embodiment of the invention in the Figure, in the present embodiment of the invention the technical proposal a clear, and complete description, obviously, the embodiment described is a part of the embodiment of this invention, not all of the embodiments. In this invention based on the embodiment of the, ordinary skill in the art in the creative work did not obtained under the premise of all other embodiments, all belong to the scope of protection of this invention.

Please refer to the Figure 1, Figure 1 is the structure diagram of the invention provides a log read that applies to the server implementation of the device of example one.

This is applied to the server log reading device comprises:

In the server of the BMC 1st UART interface T1 is connected to the signal conversion chip 1, for the UART signal conversion for the USB signal; wherein 1st UART interface T1 is used for outputting the system log; BMC for pre-the output BMC management log of the 2nd UART interface T2 function integrated in the 1st UART interface T1 physical output line;

Arranged on the outer side of the case of the server, with the signal converting chip 1 is connected to the USB connector of 2;

The function switching device 3, for in the case of the cover does not open under the condition received by the user demand instruction should live success and can be instruction, so as to be received in the BMC function command corresponding to the switching 1st UART interface after T1 two function, so that the user through the USB connector 2 corresponding to the reading system log or BMC management log.

In particular, known server log comprises a system log and BMC management log, log by the BMC on two of the UART interface one to one of the two should be output. Based on this we can know, two UART interface has different functions, a UART interface is used for outputting the system log, another UART interface is used for outputting the BMC management log, it is because of this reason, the user wants to read two log, it will also need to tool are respectively inserted to the two UART interface. Therefore, the application of the internal coding of the BMC in advance through a UART interface function integrated in another UART interface on the physical output, makes another UART interface has two functions of the (according to the BMC performance, this is the output BMC management log of the UART interface function integrated in the output system log of the UART interface physical output line).

The application of the output of the system journal UART interface is defined as the 1st UART interface T1, output BMC management log of the UART interface is defined as the 2nd UART interface T2, so integrated after 1st UART interface of T1 has two functional (i.e. not only can output the system log can output BMC management log). Based on this, the application log reading device comprises a signal conversion chip 1, USB connector 2 and the function switching device 3, its working principle is:

Taking into account the 1st UART interface T1 has two functions, the application setting function switching device 3 is used for realizing the 1st UART interface T1 function of two switching, to meet the needs of the user of the current reading. In particular, the function switching device 3 first receiving user demand instruction, here the user needs instruction is a system log demand instruction or management log demand instruction, the two transmitted by the user; then according to user's demand instruction corresponding to the instruction generation function and outputs to the BMC, here the function of the instruction is a system log function instruction (with corresponding to the system log demand instruction) or management log function instruction (with corresponding to the management log demand instruction). It should be stated, that the function of the switching device 3 receives the user demand instruction this action in the outside of the case of the implementation of the server, the user does not need to open the casing cover can realize the 1st UART interface T1 function of two switching.

In the BMC receive the system log function after the order, make the 1st UART interface T1 at this moment has the function of the output of the system journal. At the same time, signal conversion chip 1 will be 1st UART interface T1 at this time the output of the UART signal (system log) is converted into the USB signal, and the USB signal output to the USB connector 2. The application of the USB connector 2 is arranged on the outer side of the case of the server, the user in preparing for reading server log does not need to open the casing cover, with the USB connector can be 2 matching tool is inserted to the USB connector 2 in order to read to the system log, thus simplifying the reading process, saves time, and improves the reading efficiency.

Or, BMC in response to receiving the management log function after the order, make the 1st UART interface T1 at this moment has output BMC management log function. By the same token, in this case, the user directly to the outer side of the tool is inserted to the case of the USB connector 2 can be read to the BMC management log. The visible, the application through the function integrated to achieve a USB connector 2 can output system log, and can output BMC management log, so if users want to continuous reading system log and BMC management log, only need to use the function switching device 3 control BMC switching 1st UART interface T1 two function can, without plugging tool, thereby reducing the number of plugging of the fixture, improving the user experience effect.

Further, the application of the BMC can be but not limited to the specific selected AST2500BMC, signal conversion chip 1 can be but not limited to the specific selected CY7C65213 chip, the application in this did not particularly limited. Please refer to the Figure 2, Figure 2 is the structure diagram of the invention provides a log read that applies to the server implementation of the device of example two. AST2500BMC with server logs in the two relevant UART interface are: UART1 (TXD1/RXD1) and UART5 (TXD5/RXD5), UART1 is used for outputting the system log, UART5 is used for outputting the BMC management log. BMC UART5 through the internal coding can be integrated in the function of UART1 physical on the output line, namely the BMC only control UART1 output can be realized UART1 and UART5 function. Of the BMC UART1 with CY7C65213 chip: TXD1 with CY7C65213 chip is connected to the RXD, RXD1 with CY7C65213 chip connected to the TXD (two-way communication), thereby realizing the signal conversion to end use USB connector 2 output USB signal, for a user to read.

The present invention provides a is applied to the server log reading device, comprises a signal conversion chip, USB connector and the function switching device. In the present application server of the BMC 2nd UART interface integrated in the function of the 1st UART interface physical on the output line, in other words, only by the BMC 1st UART interface, can realize the above-mentioned two UART interface function (that can be output system log can output BMC management log). Based on this, the function switching device according to user's demand control switching 1st UART interface BMC two function, so that the 1st UART interface according to the user requirement corresponding output system log or BMC management log (UART signal). Then, the signal converting chip UART signal conversion for the USB signal, and outputs to the USB connector, the user will match the USB connector of the USB connector is inserted to the tool, which corresponds to reading system log or BMC management log.

Since the USB connector is arranged on the outer side of the case of the server, the user in preparing for reading server log does not need to open the casing cover, thus simplifying the reading process, saves time, and improves the reading efficiency; and, because the 1st UART interface has two functions, the user on the outside by means of the function switching device under the condition of, without plugging tool can be continuously read the system log and BMC management log, thereby reducing the number of plugging of the fixture, improving the user experience effect.
