-## Front Panel Pinout
+Helios64 provides a 24-Pin header (P3) for an external front panel in order to expose system buttons and LEDs.
 
-Helios64 provides 24 front panel pinout on header P3.
+![P3 Location](/helios64/img/front-panel/fp_header.jpg)
-User can connect the front panel PCB into the P3 in the Helios64 board by using provided ribbon cable.
-The ribbon cable are provided when you buy the Full Bundle of the Helios64 board.
-Below Graphics and Table describe the layout of the front panel header.

-## Wiring Diagram
+### Wiring Example
 
-This Figures describe the PCB layout from the left hand side (RHS) and right hand side (LHS) view respectively.
+**LED wiring:**
-The vertical mounting of this double-sided PCB will make the front panel have two LED indicators (red and green) for Sys and HDD 1 untill HDD 5 Activity Status(or Error Status).

+![P3 LED Wiring](/helios64/img/front-panel/fp_led_wiring.jpg)
 
-![Front Panel PCB LHS](/helios64/img/front-panel/fp-pcb-lhs.png)
+*LED output pins are Active High.*
 
-There is provided ribbon connection from the P3 at the Helios64 board to the P2 at the front panel PCB.
+**Button wiring:**
-So you can easily connect this two parts.
+
+![P3 Button Wiring](/helios64/img/front-panel/fp_button_wiring.jpg)
+
+*Button input pins are Active Low.*
+
+## Helios64 Enclosure
+
+The official Helios64 enclosure comes with a specially designed front panel that connects to the 24-Pin header (P3) and USB 3.0 Port (J1). This front panel exposes all the LEDS and Buttons required to operate the Helios64 NAS along with an USB 3.0 port for data loading / offloading.

+
+### PCB Details
+
+![Front Panel PCB RHS](/helios64/img/front-panel/fp_pcb_render.jpg)
+
+* All switches are push buttons.
+* All Error LEDs are red while Status / Activity LEDs are blue.
+* USB 3.0 Port is provided by a USB 3.0 Type A Female to Male extension cable.
+

+
+### PCB Wiring
+
+The Helios64 Front Panel is already mounted with the USB 3.0 extension cable and with a ribbon cable + header snapped to the ICD connector (P1).
+
+The wiring between Helios64 main board and the front panel is illustrated in figure below:

+![Front Panel Connection](/helios64/img/front-panel/fp_pcb_wiring.jpg)
 
 !!! Warning
-        Please be careful with the header polarity. Make sure that Pin no 1 at the P3 of Helios64 are connected to the no 1 at the P1 of front panel PCB.
+    Please be careful with the 24-Pin header polarity. Make sure that Pin 1 of main board P3 header is connected to the Pin 1 of front panel P1 ICD connector.
-
-The front panel USB 3.0 port can be directly connected to the Front USB 3.0 Port on the board, this interface are connected with regular USB 3.0 complied cable.
