Embodiment 1

[0019] Such as figure 1 As shown, a multifunctional signal indicator button, the multifunctional signal indicator button is integrated with a power button and two red and green light-emitting diodes, the button end is connected to the power-on control signal FP_PWRBTN_N, when the power button is pressed, FP_PWRBTN_N becomes low level and sent to the PCH unit, then the PCH will send a power-on signal to the CPLD, and finally the CPLD will start the power-on sequence control of the main board to realize the normal power-on action of the main board system.

[0020] The power indicator signal, alarm signal and power-on control signal are only integrated on one signal light button to simplify the design of the signal light and save board space.

[0021] At the same time, realizing the two signal indications through one signal light can enable the staff in the computer room to better monitor the working status of the server and perform daily maintenance of the server.

Embodiment 2

[0023] On the basis of Embodiment 1, in this embodiment, when the main board is turned on normally, the green light-emitting diode in the multi-function signal indicator button is controlled to be turned on through the power state normal signal POWER_LED. At this time, the green light is on, indicating that the system has been turned on. The power supply is working normally.

Embodiment 3

[0025] On the basis of Embodiment 1, in this embodiment, when the motherboard system fails, the red light-emitting diode in the multi-function signal indicator button is controlled by the power state alarm signal ERROR_LED to turn on, and the red light is on at this time, indicating that the system has Fault.

Abstract

The invention discloses a multifunctional signal indicating lamp button. A button, a red LED and a green LED are integrated in the multifunctional signal indicating lamp button, the button end is connected to a power-on control signal FP_PWRBTN_N, when the Power button is pressed, the FP_PWRBTN_N is changed into a low level, and sent to a PCH unit, the PCH sends a power on signal to a CPLD, the CPLD starts power-on time sequence control of a mainboard, and a mainboard system is powered on normally. According to the invention, power indication, alarm and power-on control signals are controlled by one signal lamp, the single signal lamp is multifunctional, and the PCB occupation area can be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of server motherboard design, in particular to a multifunctional signal indicator button. Background technique [0002] With the advent of the information age, the continuous expansion of the application scope of the Internet, and the emergence of online approval, online shopping, and online banking payment services, many businesses in people's work and life are showing the development trend of informationization. What came into being is the rise and development of cloud computing technology and the arrival of the era of big data. The server as the basis of these technologies also needs to make breakthroughs and improvements in the original technology. [0003] In the routine maintenance work of the server, it is necessary to use signal lights to indicate the working status of the system. In order to prevent power-off problems caused by overheating of the chassis, the indicator light will enter an alarm st...
