# UGREEN dx4600 pro led driver install script for TrueNAS Scale.md

UGREEN led driver installer for TrueNAS Scale

1. find url to raw file from pre-built binary branch
2. run following command and replace the <replace some url here> with the url you find

URL_TO_KO_FILE=<replace some url here>

curl -sSLo- "https://gist.github.com/arnesacnussem/fb76560a988bb405b52277df953a6320/raw/install.sh" | bash - "$URL_TO_KO_FILE" enp3s0

I've tested this on my dx4600 pro with truenas scale 24.04.2 and 24.10.0

This script is for install a pre-built led-ugreen.ko file and config it on TrueNAS Scale

driver source from miskcoo/ugreen_dx4600_leds_controller

script is inspired by comment from sgreiner

pre-built binary from gh-action branch of source repo

as pointed by sgreiner, you can put a startup script to make power led not blinking
