Mikrotik CRS309-1G-8S+IN - All LED lights on ports always on

Got a Mikrotik CRS309-1G-8S+IN.

Can’t understand why are all the LED lights on the ports always on.

Have updated firmware to v 7.20.1 just in case, but same behaviour.

Have also disabled all rules on System >

LEDs list, but same behaviour as well.

Is it related to slaving rules on ports?

Maybe the old config is not treated correctly in the new RouterOS, you could also try update the firmware (RouterBoot) to the latest and also doing a default config reset.
