What is the front panel of the motherboard?
Have you ever wondered what the motherboard is and what it is for? This is the operations center which contains a number of slots and connectors. It contains a front panel with a series of pins that allow the connecting cables to turn on the computer, use the LED indicators on the case, activate the front USB ports, and use the internal speaker or speaker to infer any errors on the motherboard.
The cables or connectors of the computer case (chassis)
Il equipment cabinet contains a "HDD LED" cable or hard disk indicator light, a "POWER LED" cable which is the power indicator of the equipment, a "POWER SWITCH" cable to turn the computer on and off, a "SPEAKER" cable ”For the internal speaker and a“ Reset SW ”cable for the“ Reset ”button.
How to connect the front panel cables of my PC motherboard?
La procedure to connect the cables of the front panel of the motherboard it is not complex but must be done carefully. For this reason, it is convenient to follow the steps that we indicate below so that you can complete this task successfully and without any inconvenience.
Open the cabinet or case
First of all, it is necessary open the cabinet or case. To do this, put on an antistatic wrist strap and take a screwdriver. Loosen the screws that secure the housing cover, remove the cover and set it aside. Make sure you change the motherboard BIOS battery if you notice that the date on your computer is constantly changing.
Prepare the USB cables
Remove the zip tie that binds the USB cables to the front of the case. Therefore, separate the individual pin connectors to display the name of each.
Locate the motherboard connection panel
Often, the connection panel for the motherboard yes located at the bottom right of the motherboard. You can easily identify it because each pin is labeled with the name of a connector. Some motherboards have the word "PANEL" on the side of this header.
Recognizes the cable load
Some cables printed a negative or positive value with respect to the load. If your cables don't indicate it, you can be guided by color. The white wires represent the negative charge, while the other colors are positive. If both cables are black, make sure the connector name is facing out.
Connect the cables to the motherboard
Each pair of cables must be connected exactly where the motherboard patch panel indicates. Depending on the model and type of card, you will see that in most cases the connector name is abbreviated, replacing “POWER SWITCH” with “PWR SW” or “POWER LED” with “P LED”. This is due to the limited space on the motherboard. You can use this step to repair and install the power button if you believe the component is faulty.
Connect connects cables from the front panel of your PC motherboard
Commonly, USB 2.0 cable has nine pins and one blind pin so we can only connect it one way. On the motherboard you will see the connector labeled "USB". The USB 3.0 cable has twenty pins and you can connect it to the blue connector located at the bottom right of the board.
Importantly, the USB 3.0 cable must also be connected in one way. For this, check the protrusion (male connector) and the recess where this protrusion fits.
Recommendation on the "SPEAKER" connector
The "SPEAKER" cable must be connected to a connector on the motherboard which consists of four pins even if this cable only has two. The “SPEAKER” connector is optional but it is very useful for motherboard diagnosis as it makes different sounds or beeps when it has a fault. Therefore, regardless of whether or not you have one of the best motherboard types, you should know that they all share the same front panel.
