Problems solved by technology

[0003] However, the current testing of LED lamps in the industry is limited to manual unit testing, which cannot be integrated into the running process of the server system to test the entire LED power supply link.
Moreover, there are more than 20 LED lights on the main board of the server, and it is very troublesome to check them one by one.

Embodiment Construction

[0034] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0035] Such as figure 1 , figure 2 Shown is a method for automatically testing the stability of server LED lights through BMC, including:

[0036] The BMC chip is linked to the switches of each LED light in the entire server system through the designated GPIO pins.

[0037] Connect the positive and negative terminals of each LED lamp in the entire server system to the ADC module for detecting the LED voltage. Then set the ADC module as the digital acquisition terminal of the server's LED lamp test voltage. As a result, the I2C test link construction between the BMC chip and the LED lamp is completed.

[0038] The BMC chip sends a light-on or light-off control command to the switch of the LED diode. Specifically: The BMC chip controls the BMC chip to send a light-on or light-off control signal to the designated LED light through the preset OEM raw command 1 command. ...

Abstract

The invention provides a method for automatically testing the stability of an LED lamp of a server through a BMC. The method comprises the following steps: building an I2C test link of a BMC chip andthe LED lamp; transmitting, by the BMC chip, a control signal to a switch of the LED lamp, and acquiring test voltage of the LED lamp through the I2C test link; and comparing the test voltage with standard working voltage of the LED lamp to obtain a test result of the LED lamp. The method provided by the invention realizes automatic test of the stability of all the LED lamps in an entire system ofthe server through the BMC, so that the development test period is greatly shortened, and the maintenance efficiency and the accuracy are improved.

Description

Technical field [0001] The invention relates to the technical field of server component testing, and more specifically, to a method for automatically testing the stability of a server's LED light through a BMC. Background technique [0002] LED lights are commonly used components on the server motherboard. The health of the server can be judged by the color and status of the LED lights. LED lamps are energy-saving, high-brightness, long-life, and low-failure rate. They have become the favorite light-emitting body in various electronic equipment industries. However, a low failure rate does not mean no failure. When the LED lamp fails, it will greatly affect the operation and maintenance engineer's understanding of the server's operating status. Sometimes, the function of the LED lamp in the development stage can bring problems to the development engineer. Misleading. Therefore, how to ensure the correct display of the LED indicator becomes an important link in the test phase. [...
