Description of the drawings
Attached drawing 1 is the realization schematic diagram of the present invention.
Specific implementation mode
The invention will be further described in the following with reference to the drawings and specific embodiments.
The present invention provides a kind of method that server system after preventing BMC from failing overheats, and the present invention is normal by monitoring BMC
Working condition is the periodically pulsing signal sent out, determines whether BMC is in failure state.By determining state, realize
The signal gating of gating line ensures that fan remains able to the fan control letter generated according to impulse generator after BMC failures
Number work, ensure the normal heat sinking function of system.
As shown in Fig. 1, specific implementation process is：
In server internal, the controller using BMC as rotation speed of the fan, and BMC is exported in normal operation
Periodically pulsing signal connects microcontroller as feeding-dog signal, by BMC chip, prison of the microcontroller as BMC working conditions
Unit is surveyed, the feeding-dog signal is lost by monitoring BMC, the monitoring whether worked normally to BMC is realized, whether understands current BMC
In normal operating conditions, after BMC fails, regulates and controls rotation speed of the fan, ensure the proper heat reduction of system.
In above-mentioned steps, using the gate of alternative as failure rear fan control signal and normal control signal
Switching selection；Periodically pulsing signal is generated using impulse generator, the fan control signal after failing as BMC, control
The rotating speed of fan.
By the monitoring unit of BMC, i.e. microcontroller, impulse generator and gate is realized：To wind after BMC failures
The control of fan makes fan be still within the working condition of controllable rotating speed, normal for the heat dissipation and function that ensure system, here
