Problems solved by technology

[0002] During the test or maintenance process of the whole server, there will be a problem that the hard disk backplane LED cannot be turned on due to abnormal functions. At this time, it is necessary to repair the abnormal hard disk backplane and then assemble the corresponding hard disk backplane to the whole server. The disadvantages of this operation are as follows: 1. Repeated assembly, tedious work; 2. Need to enter the Linux system to test the LED function, and the efficiency is low

Embodiment 1

[0037] This embodiment provides a hard disk backplane LED light testing method, including the following:

[0038] Please refer to figure 1 and figure 2 , add the corresponding voltage (normally 3.3V) to the LED voltage Pin on the backboard of the repaired hard disk through CONN (the first power supply pin) on the backboard, and the negative pole of the LED also passes through the CONN (second power supply pin) on the backboard. ) is connected to the corresponding control IO port of the controller. The controller adopted in this embodiment is a single-chip microcomputer.

[0039] When the connection is completed, press the corresponding control switch, the controller executes the preset test command combination (including low potential control command, low potential duration and high potential control command), firstly send the low potential control command, let the LED correspond to the IO port From high level to low level, at this time there is a voltage difference betwee...

Abstract

The invention provides a hard disk backboard LED lamp test method comprising the following steps: connecting the anode of a to-be-tested LED lamp with a first backboard power supply pin, and controlling the first backboard power supply pin to output a constant voltage; the negative electrode of the LED lamp to be tested is connected with the controller through a second backboard power supply pin; the electric potential of the second backboard power supply pin is controlled through the controller so that power-on and power-off control of the to-be-tested LED lamp can be realized. According to the method, the hardware damage risk caused by repeated disassembly and assembly of the hard disk backboard of the whole server can be reduced, operation under a Linux system is not needed, the waiting time is shortened, and the test efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a method for testing an LED light on a hard disk backboard. Background technique [0002] During the test or maintenance process of the whole server, there will be a problem that the hard disk backplane LED cannot be turned on due to abnormal functions. At this time, it is necessary to repair the abnormal hard disk backplane and then assemble the corresponding hard disk backplane to the whole server. The disadvantages of this operation are as follows: 1. Repeated assembly and cumbersome work; 2. It needs to enter the Linux system to test the LED function, and the efficiency is low. Contents of the invention [0003] Aiming at the above-mentioned deficiencies of the prior art, the present invention provides a method for testing LED lights on a hard disk backplane to solve the above-mentioned technical problems. [0004] The invention provides a method for testing an...
