Problems solved by technology

However, when the server is in the process of starting up and entering the operating system, it is often difficult for the CPLD to control the error light before the system enters an operable state, so the error light often appears to be on during the server's power-on process, which is easy to cause problems. The user brings wrong guidance instructions, making the user misunderstand that the HDD is abnormal, resulting in unclear status instructions

Embodiment Construction

[0012] see figure 1 , a preferred embodiment of the present invention provides an indicator light control system 100, which is applied to a hard disk drive (hard disk drive, HDD) backplane 1 of an electronic device. The indicator light control system 100 can run after the system of the electronic device is started, that is, run after it is turned on. The indicator light control system 100 is used for controlling an indicator light 10 . The indicator light control system 100 includes the indicator light 10, a complex programmable logic device (Complex Programmable Logic Device, CPLD) module 20, an integrated south bridge (Platform Controller Hub, PCH) module 30, a basic input output system (Basic Input Output System , BIOS) module 40 and buffer 50. Wherein, the indicator light 10 , CPLD module 20 and buffer 50 are arranged on the HDD backplane 1 , and the PCH module 30 and BIOS module 40 are arranged on the main board 2 of the electronic device.

Abstract

The invention provides an indicator light control system which is applied to an HDD backboard of an electronic device. The system comprises an indicator light, a CPLD (Complex Programmable Logic Device) module, a PCH (Platform Controller Hub) module and a buffer; the CPLD module is used for controlling the state of the indicator light and electrically connected with the indicator light through the buffering device as well as being electrically connected with the buffering device; after the system of the electronic device is started and before entering the operation system, the PCH module controls the buffering device to intercept so as to enable the indicator light to be free from the control of the CPLD module, and as a result, the indicator light can be in an off state; when the electronic device enters the operation system, the PCH module controls the buffering device to be connected, and then the indicator light is controlled by the CPLD module again. The invention further provides an electronic device using the indicator light to control the system.

Description

technical field [0001] The present invention relates to an indicator light control system, in particular to an indicator light control system on a hard disk drive (HDD) backplane and an electronic device using the indicator light control system. Background technique [0002] In a server, multiple HDDs are often required to be connected to the HDD backplane at the same time to achieve the purpose of storing data in a large capacity. Usually, two indicator lights are provided corresponding to each HDD on the HDD backboard to indicate the working status of the HDD, including an in-position indicator light and an error reporting indicator light. Usually, the error indicator light is controlled by a complex programmable logic device (Complex Programmable Logic Device, CPLD) on the HDD. However, when the server is in the process of starting up and entering the operating system, it is often difficult for the CPLD to control the error indicator before the system enters an operable ...
