Abstract

A system is applied to control indicator lights for non-volatile memory express solid state disk (NVMe SSD). The system includes a NVMe SSD, a complex programmable logic device (CPLD), a controller and a slave processor. The NVMe SSD has a control module for transmitting a disk position signal. The CPLD is electrically connected to the control module so as to receive the disk position signal. The controller is electrically connected to the CPLD to light up a location indicator light. The slave processor is electrically connected to the control module and a fail indicator light. When the slave processor detect the NVMe SSD is operated under an abnormal condition, a fail signal is transmitted to light up a fail indicator light.

First claim

What is claimed is:

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.

2 . The system to control indicator lights for NVMe SSD of claim 1 , wherein the controller is a platform controller hub (PCH).

3 . The system to control indicator lights for NVMe SSD of claim 2 , further comprising a main board, and the PCH is located on the main board.

4 . The system to control indicator lights for NVMe SSD of claim 1 , wherein the control module is electrically connected to a operation indicator light, and the operation indicator light is lighted up when the NVMe SSD is operated normally.

5 . The system to control indicator lights for NVMe SSD of claim 1 , further comprising a processor, and the control module including a peripheral component interconnect express (PCIe) port electrically connected to the processor.

6 . The system to control indicator lights for NVMe SSD of claim 5 , further comprising a main board, and the processor being located on the main board.

7 . The system to control indicator lights for NVMe SSD of claim 6 , wherein, the CPLD is located on the main board.

8 . The system to control indicator lights for NVMe SSD of claim 1 , wherein, the control module further comprises an inter integrated circuit port, and the slave processor is electrically connected to the inter integrated circuit port through the I2C bus.

9 . The system to control indicator lights for NVMe SSD of claim 1 , wherein the slave processor includes a register, for storing at least a read/write data from the NVMe SSD to recognize whether the NVMe SSD is operated under the abnormal condition.

10 . The system to control indicator lights for NVMe SSD of claim 1 , further comprising a back plate, and the slave processor is located on the back plate.
