-### Wiring Diagram
-
-Since the signals to control the LEDs are active low, connect the pin to LED's cathode.
-Below a wiring diagram example.

-!!! note
- **ata** trigger requires additional patch to mainline kernel. The patch can be found [here](/helios4/files/led/libata_leds_trigger_mvebu.patch). **Armbian** builds are already patched, so no action is required.
-
-The LEDs can be accessed under LEDs class in *sysfs*.

-### LEDs Trigger
-
-- none
-
-No automatic trigger. Manually control the LED by manipulating "brightness".
-More info see [Configuring LED trigger](#configuring-led-trigger).
-
-- heartbeat
-
-LED "double" flashes at a load average based rate. The interval might change during heavy load.
-If the LED no longer blinks, it means the system is locked-up or hung and has to be reset.
-
-- ata*N*
-
-LED blinks on any read/write activity at specific SATA port.
-
-- usb-host
-
-LED blinks on USB activity at any port.
-
-- panic
-
-This trigger allows LEDs to be configured to blink on a kernel panic.
-
-- timer
-
-This allows LEDs to be controlled by a programmable timer via *sysfs*. delay_on to set how long
-the LED turned on and delay_off to set how long the LED turned off.
-
-
-### Configuring LED trigger
-
-To configure, simply set the trigger type. For example to set Status LED triggered by timer
-
-```
-echo timer | sudo tee -a /sys/class/leds/helios4\:green\:status/trigger
-```
-
-Some of the triggers may expose additional parameters that can be configured further.
-
-On **none** trigger, to turn ON the LED set the brightness bigger than 0.
-
-```
-echo 1 | sudo tee -a /sys/class/leds/helios4\:green\:status/brightness
-```
-
-and to turn OFF the LED set the brightness to 0.
-
-```
-echo 0 | sudo tee -a /sys/class/leds/helios4\:green\:status/brightness
-```
-
-On **timer** trigger, it will exposed *delay_on* and *delay_off* with default value of 0.5 seconds for both.
-To change the delay, set the respective parameter (value in milliseconds)
-
-```
-echo 1000 | sudo tee -a /sys/class/leds/helios4\:green\:status/delay_on
-echo 200 | sudo tee -a /sys/class/leds/helios4\:green\:status/delay_off
-```
-
-!!! note
- The changes is not retained across reboot. Use startup script or udev rules to make it permanent.
-
-### Configuring Fault LED
-
-While other LEDs are preconfigured, the fault LED remains unconfigured (trigger:**none**).
-
-#### 1. As Kernel Panic Indicator
-
-To configure the LED as Kernel panic indicator, set the trigger to **panic**. However this functionality might be redundant with Status LED, since if a kernel panic occurs and/or system hangs, the Status LED will no longer blink.
-
-To trigger kernel panic to test the LED, run
-```
-echo c > /proc/sysrq-trigger
-```
-
-!!! warning
- Triggering kernel panic can lead to data loss. Use with caution!
-
-#### 2. As RAID Fault Indicator
-
-To configure the LED as RAID fault indicator, please refer to [MDADM: Configure Fault LED](/helios4/mdadm/#configure-fault-led)
-
-!!! note
- On Armbian builds, this is the default setting for fault LED.
