Abstract
A switching circuit is arranged on a mainboard of a server and comprises a temperature sensor, a substrate management controller, a toggle switch and an integrating southbridge. The substrate management controller is connected with the temperature sensor to read a peripheral temperature value sensed by the temperature sensor. As the peripheral temperature value excesses a preset value, the substrate management controller outputs off signals to the integrating southbridge. The toggle switch is connected between the substrate management controller and the integrating southbridge. The integrating southbridge is used for receiving the signals of the substrate management controller to start or stop the server. The switching circuit decides whether or not to start the high-temperature power off function of the server.

Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 1, on-off circuit 10 of the present invention is arranged on a server master board, and the better embodiment of described on-off circuit 10 comprises a baseboard management controller 20, three toggle switch 30-32, integrated south bridge 40 and a temperature-sensitive sticker 50.
Described baseboard management controller 20 is connected to read the environment temperature that described temperature-sensitive sticker 50 senses with described temperature-sensitive sticker 50; The first end of described first toggle switch 30 is connected to the first signal pins GPIO1 of described baseboard management controller 20, the first end of described second toggle switch 31 is connected to the secondary signal pin GPIO2 of described baseboard management controller 20, and the first end of described 3rd toggle switch 32 is connected to the 3rd signal pins GPIO3 of described baseboard management controller 20; The temperature protection pin TEM of described integrated south bridge 40 is connected to the second end of described first toggle switch 30; described integrated south bridge 40 restart the second end that pin RST is connected to described second toggle switch 31, the system switching pin PWR of described integrated south bridge 40 is connected to the second end of described 3rd toggle switch 32.In the present embodiment, the first signal pins GPIO1 of described baseboard management controller 20 is for exporting high temperature off signal, and its secondary signal pin GPIO2 is for exporting Restart Signal, and its 3rd signal pins GPIO3 is used for output switch machine signal.
The shift bar stirring described toggle switch can make first and second end of toggle switch connect or disconnect.When toggle switch handle makes first and second end of described toggle switch 30-32 connect; first to the 3rd signal pins GPIO1-GPIO3 of described baseboard management controller 20 be connected respectively described integrated south bridge 40 temperature protection pin TEM, restart pin RST and system switching pin PWR; when toggle switch handle makes first and second end of described waved switch 30-32 disconnect, described baseboard management controller 20 disconnects the connection with described integrated south bridge 40.
When needing described server master board normally to use; first end and second end of described toggle switch 30-32 are all in connection status, and the first to the 3rd signal pins GPIO1-GPIO3 correspondence of described baseboard management controller 20 connects the temperature protection pin TEM of described integrated south bridge 40, restarts pin RST and system switching pin PWR.Described baseboard management controller 20 reads the environment temperature of described temperature-sensitive sticker 50 sensing; when the environment temperature sensed is more than a preset value; described baseboard management controller 20 exports a high temperature off signal by described first signal pins GPIO1, and the temperature protection pin TEM of described integrated south bridge 40 receives closing server mainboard after described high temperature off signal.When the environment temperature that described temperature-sensitive sticker 50 senses does not exceed described preset value, described baseboard management controller 20 can by its secondary signal pin GPIO2 and described toggle switch 31 export Restart Signal give described integrated south bridge 40 restart pin RST, control described computer main board after described integrated south bridge 40 receives described Restart Signal and restart; Described baseboard management controller 20 also can give the system switching pin PWR of described integrated south bridge 40 by its 3rd signal pins GPIO3 and described toggle switch 32 output switch machine signal, control the start of described computer main board or shutdown after described integrated south bridge 40 receives described switching on and shutting down signal.
Disconnect first and second end of described toggle switch 30-32, when described environment temperature is more than a preset value, the high temperature off signal of described baseboard management controller 20, Restart Signal and switching on and shutting down signal all cannot export described integrated south bridge 40 to, now server master board can not be closed, when the temperature of server being carried out to reliability testing exceedes described preset value, server master board normally will work to test and carries out smoothly.
According to described on-off circuit 10, user can select the temperature protection function whether enabling server.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not depart from the spirit and scope of technical solution of the present invention.
