The invention provides a
server board burning prevention
system and a working method. The
system comprises a
power module, a board burning prevention
chip, a BMC and a CPLD. The power supply module supplies power to different parts of the
server through a parallel
resistor by an output power supply; the anti-burning board
chip is respectively connected with the output end and the output end of theresistor; the anti-burning board
chip is connected with the CPLD; the CPLD is connected with the BMC, and the BMC is further connected with the anti-burning board chip and the power supply module; when
overcurrent occurs in any power supply line, the burn-proof board chip outputs a stop operation
signal to the CPLD. After the CPLD receives the interrupt
signal, the CPLD sends the interrupt signalto the BMC, and the BMC judges an
overcurrent address, stores a log and sends a power-off instruction to the
power module. Based on the
system provided by the invention, the invention further provides a working method of the anti-burning plate. The board burning prevention chip is additionally arranged, the abnormal position can be quickly positioned and recorded, meanwhile, the
power output voltage is turned off, and the board burning phenomenon caused by the abnormal phenomenon is prevented.
