Front panel connections: HDD LED (hard disk light), power (on/ off) switch and RESET switch in the top row. Below: mini speaker.
All motherboards group the pins that provide front panel functions at the bottom right of the board. You should find these described in the handbook that came with your motherboard. The abbreviations printed on the board itself are not particularly helpful for beginners, who may find the following short explanation of the abbreviations useful.- SP, SPK, or SPEAK: the loudspeaker output. It has four pins.
- RS, RE, RST or RESET: connect the two-pin Reset cable here.
- PWR, PW, PW SW, PS or Power SW: power switch, the PC's on/ off switch. The plug is two-pin.
- PW LED, PWR LED or Power LED: the light-emitting diode on the front panel of the case illuminates when the computer is switched on. It is a two-pin cable.
- HD, HDD LED: these two pins connect to the cable for the hard disk activity LED.
Final Check
Congratulations - you've done it! You have fitted and connected all components. Before you boot your new computer for the first time, recheck everything. It is very easy to overlook something obvious.Consider the following:
- Motherboard jumper configuration: are the settings for the processor correct?
- Drive jumper settings: master/ slave correct?
- Are the processor, RAM modules and plug-in cards firmly seated in their sockets?
- Did you plug all the cables in? Do they all fit snugly?
- Have you tightened all the screws on the plug-in cards or fitted the clips?
- Are the drives secure?
- Have you connected the power cables to all drives?
