Where does led/rgb sw plug into the motherboard?

led/rgb sw should be directly plugged into the light bar inside the chassis panel; generally, there is a button with the word "RGB" on the front panel of the chassis with a colored light bar, and the wiring below this button "LED SW" will be written on the head, and the connector has two pinholes. This LED SW controls the color of the chassis light.

#The operating environment of this tutorial: Windows 10 system, Dell G3 computer.

led/rgb sw Where is it plugged into the motherboard?

The extra LED SW on the chassis is used to control the color change of the chassis lights and should be directly plugged into the light strip inside the chassis panel.

Generally, there is a button with the word "RGB" on the front panel of the chassis with a colored light bar (it may also be written with other letters, the meaning is similar), and there will be a connector under the button. Write "LED SW", the connector has two pinholes. Take out the light bar plugged into the chassis panel, and you can see that there are two pins soldered on it. The pin pitch is exactly the same as the two hole pitch of the LED SW connector. Insert the plug into the light strip, and then plug the power supply head of the light strip into the chassis power supply. Now the colored light bar will light up when the computer is turned on, and the colored light will change color after pressing the "RGB" button on the chassis.

The chassis generally includes various switches and indicator lights on the casing, brackets, and panels.

As a part of computer accessories, the main role of the chassis is to place and fix various computer accessories, and to play a supporting and protective role. In addition, the computer case plays an important role in shielding electromagnetic radiation.

Although it is not a very important configuration in DIY, using a poor-quality chassis can easily short-circuit the motherboard and chassis, making the computer system very unstable.

Chassis classification

Server chassis

For servers, the chassis is also a problem that cannot be ignored. The main problems of the server chassis include:

Temperature: How to cool the internal components of the case? The fan (usually from the power supply) should blow directly toward or over the processor.

Expansion capability: Choose a chassis with enough space for network expansion. Make sure there is enough space to add more hard drives and other peripherals. Check inside the case to make sure there are no sharp edges. This is important for technician safety and to prevent cables from being accidentally cut during future upgrades. The chassis should also provide maintenance personnel with easy access to internal components for future upgrades or troubleshooting.

Security: Because your server will hold important files and more expensive items on the network, there are security issues to consider. Server chassis should be lockable to prevent illegal disassembly.

Certification: Choose a chassis and power supply with certifications that meet the requirements of your environment. Typical certifications are FCC, UL and CE.

For general enterprise department-level servers, they usually choose 4U or above or tower servers. However, how to choose a stable and secure home for such a powerful server is an issue that is often overlooked.

Senior PC DIY players will never ignore the critical importance of the chassis and power supply in the whole machine. A high-quality power supply is the prerequisite for the stable operation of the whole machine, and a well-designed chassis can provide excellent heat dissipation on the one hand. Environment, on the one hand, it can also make full use of space and even shield electromagnetic interference. Therefore, as a server system that operates 24 hours a day, its operation stability and timely cooling methods are even more crucial factors. For servers, stability requirements even exceed slight differences in performance. If you want to choose an ideal server, you should first choose an excellent server chassis.

Instrument chassis

According to the material, it can be divided into plastic chassis, alloy chassis, composite material chassis, etc.
