Embodiment Construction

[0011] Please refer to figure 1 , the test board 100 with fan control function in this embodiment is connected between the main board 201 of the electronic device 200 and several fans 202, and is used to start the several fans 202 one by one when the electronic device 200 is turned on, so as to reduce the fan 202. The instantaneous current when the electronic device 200 is turned on. The instantaneous current generated by starting several fans 202 one by one is smaller than the instantaneous current generated by starting several fans 202 simultaneously.

[0012] Please refer to figure 2 , the test board 100 includes a plurality of first connectors 101 , a plurality of second connectors 102 , a plurality of switches 103 and a control chip 104 . Each first connector 101 is connected to a fan connector 2011 on the motherboard 201 and connected to one of the second connectors 102 . Each second connector 102 is also connected to a fan 202 and connected to the control chip 104 t...

Abstract

The invention provides a test board with a fan controlling function. The test board comprises a plurality of first connectors, a plurality of second connectors, a control chip and a plurality of switches, wherein each first connector is connected with a fan connector on a mainboard of an electronic device, and connected with the second connector; each second connector is further connected a the fan of the electronic device, and connected with the control chip through the switch; the control chip is further connected with a power supply of the electronic device; when the electronic device is powered on, the control chip sequentially opens the switch at a preset time interval. According to the test board with the fan controlling function, when the electronic device is powered on, the test board controls the plurality of fans of the electronic device to start one by one, and thus the instantaneous current when the electronic device starts up is reduced. If the electronic device can start up normally when the plurality of fans are started one by one, the phenomenon proved that the problem that the electronic device cannot start up normally due to the excessive instantaneous current when starting up can be solved by reducing the instantaneous current of the fans.

Description

technical field [0001] The invention relates to a test board, in particular to a test board with a fan control function. Background technique [0002] When an electronic device such as a server is turned on, it may fail to turn on due to an instantaneous overcurrent. When this happens, it is necessary to reduce the instantaneous current when starting up. The current of the fan in the electronic device is quite large at the moment of starting up. Reducing the current of the fan at the moment of starting up may reduce the instantaneous current of the electronic device when starting up, so as to avoid the phenomenon that it cannot be turned on. However, in the prior art, it is impossible to verify whether reducing the instantaneous current of the fan startup can make the electronic device start up normally. Contents of the invention [0003] In view of this, the present invention provides a test board with a fan control function to solve the above technical problems. [00...
