Method and system for controlling status indication light of PCIE hard disk drive
A method and a system for controlling a status indication light of a Peripheral Component Interconnect Express (PCIE) hard disk are disclosed. The method includes determining a current operation mode of the PCIE hard disk and transmitting information of the current operation mode to a southbridge chip by a CPU. The information is transmitted to a complex programmable logic device (CPLD) by the southbridge chip. The display of the status indication light corresponding to the current operation mode is controlled according to the information by the complex programmable logic device. The CPLD is controlled by the southbridge chip, to control display control of the status indication light corresponding to reset and locate operation of the PCIE hard disk. The usage status of the PCIE hard disk may be determined in real time by performing Hamming check to the information, and the accurate display of status indication light may be ensured.
