How to turn off Ethernet LED's?

I know the cable is connected, I don't need the lights to constantly flash at me. :pfff:

Using an Asrock Extreme 4 Z77 motherboard and having this issue, the red and orange lights are pretty annoying and I can't seem to find anything in the BIOS that says I can disable them, does this mean it cant be done?

Thanks.
 
Then I presume that you don't want to see them from the side. Put silicone or black tape on them. Seeing the lights from the back may be useful if there's a network issue.
