Embodiment
Please cooperate and consult Fig. 1, be depicted as the block scheme of the power on/off system embodiment of the many motherboards of the present invention.The power on/off system of many motherboards of the present invention is located in the server system 10, comprises motherboard 110,120,130,140 (110～140), administration module 200, power-on switch 310～340, and power supply unit 400.
Each component units on 111 pairs of motherboards 110 of basic input/output carries out the initialization computing, and is connected to baseboard management controller 210 by general input and output pin 211, with the input motherboard 110 power state signal to baseboard management controller 210.Each component units on 121 pairs of motherboards 120 of basic input/output carries out the initialization computing, and is connected to baseboard management controller 210 by general input and output pin 221, with the input motherboard 120 power state signal to baseboard management controller 210.Each component units on 131 pairs of motherboards 130 of basic input/output carries out the initialization computing, and is connected to baseboard management controller 210 by general input and output pin 231, with the input motherboard 130 power state signal to baseboard management controller 210.Each component units on 141 pairs of motherboards 140 of basic input/output carries out the initialization computing, and is connected to baseboard management controller 210 by general input and output pin 241, with the input motherboard 140 power state signal to baseboard management controller 210.
General input and output pin 211～241 is located on the baseboard management controller 210, and baseboard management controller 210 is connected to the basic input/output 111～141 of motherboard 110～140 respectively by general input and output pin 211～241.And, by the general input and output pin 211～241 of each motherboard correspondence, a power state signal of each motherboard 110～140 can be inputed to baseboard management controller 210.
Power-on switch 310～340 is respective hosts plate 110～140 one by one, and power-on switch 310～340 couples baseboard management controller 210 respectively, and power-on switch 310～340 can send a request signal respectively to baseboard management controller 210.
That is, baseboard management controller 210 is by general input and output pin 211～241 one of them person, send a control signal to corresponding motherboard 110,120,130 or 140, with the power-on switch 310～340 of control respective hosts plate 110～140, thereby switch on or off 400 pairs of motherboards 110 of power supply unit, 120,130 or 140 power supply.When baseboard management controller 210 detected power state signals, namely general input/output signal is electronegative potential, represents that namely its place motherboard is in "on" position.Therefore, the mode of baseboard management controller 210 main control system plates 110～140 outage is, the current potential by the setting general-purpose input/output signal switches to noble potential from electronegative potential.On the contrary, if when baseboard management controller 210 detected power state signals, namely general input/output signal is noble potential, represents that namely its place motherboard is in not "on" position.Therefore, the mode of baseboard management controller 210 main control system plates 110～140 energising is, the current potential by the setting general-purpose input/output signal switches to electronegative potential from noble potential.So, can reach purpose by 110～140 switching on and shutting down of baseboard management controller 210 main control system plates.
Please cooperate and consult Fig. 2, be depicted as the start flow chart of steps 500 of the power on/off system of the many motherboards of the present invention.At first, select one of motherboard 110～140 start shooting (step 510) by baseboard management controller 210.Then, set one of motherboard 110～140 person by baseboard management controller 210 and transmit a power state signal to baseboard management controller 210 (step 520), wherein said power state signal inputs to baseboard management controller 210 via general input and output pin 211～241.Then, baseboard management controller 210 can be according to the described power state signal that receives, and judges corresponding motherboard whether switch on (step 530).If the judged result in the step 530 is then got back to step 510 for being, select again other motherboards are started shooting; But if the judged result in the step 530 represents namely that for not the motherboard of selecting is in the not state of energising at present.Therefore, transmit an energising control signal (step 540) by 210 pairs of corresponding motherboards of baseboard management controller, wherein said energising control signal is sent to corresponding motherboard 110～140 via general input and output pin 211～241.At last, connect the power supply unit 400 (step 560) of supply motherboard 110～140 according to described energising control signal control, be that baseboard management controller 210 is by general input and output pin 211～241, the current potential of setting general-purpose input/output signal switches to electronegative potential (step 550) from noble potential, power-on switch 310～340 with main control system plate 110～140 is connected power supply unit 400, to connect the power supply to motherboard 110～140, process ends then.So, namely finished the step by 110～140 starts of baseboard management controller 210 main control system plates.
Please cooperate and consult Fig. 3, be depicted as the shutdown procedures process flow diagram 600 of the power on/off system of the many motherboards of the present invention.At first, select one of motherboard 110～140 shut down (step 610) by baseboard management controller 210.Then, set one of motherboard 110～140 by baseboard management controller 210 and transmit a power state signal to baseboard management controller 210 (step 620), wherein said power state signal inputs to baseboard management controller 210 via general input and output pin 211～241.Then, baseboard management controller 210 can be according to the described power state signal that receives, and judges corresponding motherboard whether switch on (step 630).If the judged result in the step 630 is then got back to step 610 for not, select again other motherboards are shut down; But if the judged result in the step 630 is for being, i.e. the motherboard of expression selection has been in the state of energising at present.Therefore, transmit an outage control signal (step 640) by 210 pairs of corresponding motherboards of baseboard management controller, wherein said outage control signal is sent to corresponding motherboard 110～140 via general input and output pin 211～241.At last, cut off the power supply unit 400 (step 660) of supply motherboard 110～140 according to described outage control signal control, be that baseboard management controller 210 is by general input and output pin 211～241, the current potential of setting general-purpose input/output signal switches to noble potential (step 650) from electronegative potential, with the unit 400 of cutting off the electricity supply of the power-on switch 310～340 on the main control system plate 110～140, to cut off the power supply to motherboard 110～140, process ends then.So, namely finished the step by 110～140 shutdown of baseboard management controller 210 main control system plates.
Though the present invention discloses as above by embodiment; but be not to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; can make various changes and modification to the present invention, so protection scope of the present invention should be as the criterion with the scope that claims were defined.
