1. A system to control indicator lights for non-volatile memory express (NVMe) solid state disk (SSD), comprising:
a NVMe SSD, having a control module for transmitting a disk position signal;
a complex programmable logic device (CPLD), electrically connected to the control module for receiving the disk position signal to light up a location indicator light;
a controller, electrically connected to the CPLD to light up the location indicator light; and
a slave processor, electrically connected to the control module through an inter integrated circuit (I2C) bus, and including a general purpose I/O (GPIO) port electrically connected to a fail indicator light, wherein when the slave processor detects the NVMe SSD is operated under an abnormal condition, a fail signal is transmitted to the fail indicator light to light up the fail indicator light;
wherein the controller is a platform controller hub (PCH).
