Abstract

Disclosed is a pure NVME backplane LED status indicator lamp STBY power supply switching device. The device comprises a CPLD circuit, a detection circuit and a drive circuit; the input end of the CPLDcircuit is connected to the output end of the detection circuit, and 12V Core power and 3.3V STBY power are input from the input end of the detection circuit; the output end of the CPLD circuit is connected to the input end of the drive circuit, and the output end of the drive circuit outputs. Further disclosed is a pure NVME backplane LED status indicator lamp STBY power supply switching method.No additional power IC is required to convert the Core power, and P12V Core power can also be avoided, thereby saving resources.

Description

technical field [0001] The invention relates to the technical field of server hard disk operation, in particular to a pure NVME backplane LED status indicator STBY power supply switching device and method. Background technique [0002] In order to improve the reliability of the server hard disk operation and intuitively reflect the status of the server hard disk during use, the hard disk uses three LED lights of different colors to intuitively display information such as hard disk read and write, hard disk errors, and hard disk positioning, allowing design or maintenance Users can intuitively know the current status of the hard disk. [0003] At present, pure NVME backplanes use the power supply source of the main board or power board, mainly 12Vcore power and P3V3_STBY power. [0004] The LED drive power needs to be Core power. If P3V3_STBY power is used, the CPLD is already working when the AC is plugged in. At this time, the hard disk is plugged in, and the CPLD will dri...
