The plastic panel on the front of your computer is the Front Panel.
This is where the Power On switch, Power On LED, and HDD LED are located.
The connector on the motherboard where the cables (Wires) attach to, is the Front Panel header.
The front panel header is a series of pins, sticking up out of the motherboard.
The MSI ms-7145 motherboard, (RS480M) has the Front Panel header separated into two headers.
JFP1, and JFP2
Looking at the motherboard with the Processor socket to the top, and the Ram Memory slots to the right, the JFP1, and JFP2 front panel headers are located at the extreme bottom Right, of the motherboard.

Now go to Page 38.
Page 38 shows the connections for the JFP1, and JFP2 headers.
The JFP1 header, and the JFP2 header, consists of two rows of pins in a horizontal column.
The pins are arranged parallel, to the bottom edge of the motherboard.
Right above the JFP1, and JFP2 header may be three pins, with two of the pins have a jumper. We will not concern ourselves with this jumper header (BIOS with Protect Jumper)
The JFP1, and JFP2 headers are close together. There is no separation in-between them.
The JFP2 header is for an internal speaker.
The JFP1 header is for the Front Panel cables.
The JFP1 header pins start from the right side of the motherboard, and go towards the left.
There are 5 pins across the Bottom. (Going from right to left)
There is NO pin, then there are 4 pins across the Top.
(Again, going from Right towards the left)
The top row of pins are numbered Evenly.
The bottom row of pins are numbered Odd.
Starting on the Right side, going towards the left for the Top row of pins, the pins are numbered,
10 (NO pin for 10), 8, 6, 4, and 2.
Starting on the Right side, going towards the left for the Bottom row of pins, the pins are numbered,
9, 7, 5, 3, and 1.
1) Pins 2 and 4 are for the Power On LED.
2) Pins 6 and 8 are for the Power On switch
3) Pins 1 and 3 are for the HarDDrive activity LED
4) Pins 5 and 7 are used for a Reset switch. (If applicable)
5) Pin 9 is not used.
