Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] as attached figure 1 with 2 As shown, a blade server-based method of the present invention to realize easy plug-in of fan board modules includes the following steps: (1) Firstly, split the fan tray into fan board modules of multiple nodes, and the fan board module Groups are controlled through another separate fan control backplane;
[0022] (2) Then, connect the fan board module of each group of computing nodes to the computing board through the fan control backplane in step (1); the fan board module is provided with a fan interface, and the fan interface is connected to the fan control backplane through a connector Connection; the fan interface accepts TACH, PWM, LEDcontrol and Present signals, PWM is used to adjust the fan speed, TACH feeds back the fan speed information, when the fan is unplugged, the Present is pulled high to noti...
